Outboard motor safetyObserve these precautions at all times.EMU36502

PropellerPeople can be injured or killed if they come incontact with the propeller. The propeller cankeep moving even when the motor is in neu-tral, and sharp edges of the propeller can cuteven when stationary. Stop the engine when a person is in the

water near you.Keep people out of reach of the propeller,

even when the engine is off.EMU40272

Rotating partsHands, feet, hair, jewelry, clothing, personalflotation device (PFD) straps, etc., can be-come entangled with internal rotating parts ofthe engine, resulting in serious injury ordeath.Keep the top cowling in place whenever pos-sible. Do not remove or replace the top cowl-ing with the engine running.Only operate the engine with the top cowlingremoved according to the specific instruc-tions in the manual. Keep hands, feet, hair,jewelry, clothing, PFD straps, etc., away fromany exposed moving parts.EMU33641

Hot partsDuring and after operation, engine parts arehot enough to cause burns. Avoid touchingany parts under the top cowling until the en-gine has cooled.EMU33651

Electric shockDo not touch any electrical parts while start-ing or operating the engine. They can causeshock or electrocution.

EMU33661

Power trim and tiltBody parts can be crushed between the mo-tor and the clamp bracket when the motor istrimmed or tilted. Keep body parts out of thisarea at all times. Be sure no one is in this areabefore operating the power trim and tiltmechanism.The power trim and tilt switches operate evenwhen the main switch is off. Keep people beaway from the switches whenever workingaround the motor.Never get under the lower unit while it is tilted,even when the tilt support lever is locked. Se-vere injury could occur if the outboard motoraccidentally falls.EMU33672

Engine shut-off cord (lanyard)Attach the engine shut-off cord so that theengine stops if the operator falls overboard orleaves the helm. This prevents the boat fromrunning away under power and leaving peo-ple stranded, or running over people or ob-jects.Always attach the engine shut-off cord to asecure place on your clothing or your arm orleg while operating. Do not remove it to leavethe helm while the boat is moving. Do not at-tach the cord to clothing that could tearloose, or route the cord where it could be-come entangled, preventing it from function-ing.Do not route the cord where it is likely to beaccidentally pulled out. If the cord is pulledduring operation, the engine will shut off andyou will lose most steering control. The boatcould slow rapidly, throwing people and ob-jects forward.

GasolineGasoline and its vapors are highly flamma-ble and explosive. Always, refuel accordingto the procedure on page 53 to reduce therisk of fire and explosion.EMU33821

Gasoline exposure and spillsTake care not to spill gasoline. If gasolinespills, wipe it up immediately with dry rags.Dispose of rags properly.If any gasoline spills onto your skin, immedi-ately wash with soap and water. Changeclothing if gasoline spills on it.If you swallow gasoline, inhale a lot of gaso-line vapor, or get gasoline in your eyes, getimmediate medical attention. Never siphonfuel by mouth.EMU33901

Carbon monoxideThis product emits exhaust gases which con-tain carbon monoxide, a colorless, odorlessgas which may cause brain damage or deathwhen inhaled. Symptoms include nausea,dizziness, and drowsiness. Keep cockpit andcabin areas well ventilated. Avoid blockingexhaust outlets.EMU33781

ModificationsDo not attempt to modify this outboard mo-tor. Modifications to your outboard motormay reduce safety and reliability, and renderthe outboard unsafe or illegal to use.EMU33741

Boating safetyThis section includes a few of the many im-portant safety precautions that you shouldfollow when boating.EMU33711

Alcohol and drugsNever operate after drinking alcohol or takingdrugs. Intoxication is one of the most com-mon factors contributing to boating fatalities.

EMU40281

Personal flotation devices (PFDs)Have an approved PFD on board for everyoccupant. Yamaha recommends that youmust wear a PFD whenever boating. At a mi-nimum, children and non-swimmers shouldalways wear PFDs, and everyone shouldwear PFDs when there are potentially hazard-ous boating conditions.EMU33732

People in the waterAlways watch carefully for people in the wa-ter, such as swimmers, skiers, or divers,whenever the engine is running. When some-one is in the water near the boat, shift intoneutral and stop the engine.Stay away from swimming areas. Swimmerscan be hard to see.The propeller can keep moving even whenthe motor is in neutral. Stop the engine whena person is in the water near you.EMU33752

PassengersConsult your boat manufacturer’s instruc-tions for details about appropriate passengerlocations in your boat and be sure all passen-gers are positioned properly before acceler-ating and when operating above an idlespeed. Standing or sitting in non-designatedlocations may result in being thrown eitheroverboard or within the boat due to waves,wakes, or sudden changes in speed or direc-tion. Even when people are positioned prop-erly, alert your passengers if you must makeany unusual maneuver. Always avoid jump-ing waves or wakes.EMU33762

OverloadingDo not overload the boat. Consult the boatcapacity plate or boat manufacturer for maxi-mum weight and number of passengers. Besure that weight is properly distributed ac-cording to the boat manufacturer’s instruc-

2019 Yamaha M

tions. Overloading or incorrect weightdistribution can compromise the boats han-dling and lead to an accident, capsizing orswamping.EMU33773

Avoid collisionsScan constantly for people, objects, and oth-er boats. Be alert for conditions that limit yourvisibility or block your vision of others.

Operate defensively at safe speeds and keepa safe distance away from people, objects,and other boats.Do not follow directly behind other boats or

waterskiers. Avoid sharp turns or other maneuvers that

make it hard for others to avoid you or un-derstand where you are going.

Avoid areas with submerged objects orshallow water.

Ride within your limits and avoid aggres-sive maneuvers to reduce the risk of loss ofcontrol, ejection, and collision.

Take early action to avoid collisions. Re-member, boats do not have brakes, andstopping the engine or reducing throttlecan reduce the ability to steer. If you are notsure that you can stop in time before hittingan obstacle, apply throttle and turn in an-other direction.

EMU33791

WeatherStay informed about the weather. Checkweather forecasts before boating. Avoidboating in hazardous weather.EMU44161

Accident reportingBoat operators are required by law to file aBoating Accident Report with their boatinglaw enforcement agency if their boat is in-volved in any of the following accidents:1. There is loss of life or probable loss of

life.2. There is personal injury that requires

medical attention beyond first aid.3. There is property damage to boats or

other property over a certain amount.4. There is complete loss of a boat.Contact local law enforcement personnel if areport is necessary.EMU44171

Boat education and trainingFor U.S.A.Operators should take a boating safety cour-se. This may be required in your state. Manyof the organizations listed in the next sectioncan provide information about courses inyour area.You may also want to consider an Internet-based program for basic boater education.The Online Boating Safety Course providedby the BoatU.S. Foundation, is approved bythe National Association of State BoatingLaw Administrators (NASBLA) and recog-nized by the United States Coast Guard.Most, but not all, states accept this course tomeet their minimum requirements. While itcannot replace an in-depth course such asone offered by the U.S. Coast Guard, U.S.Power Squadron, or other organization, thisonline course does provide a general over-view of the basics in boating safety, require-ments, navigation, and operation. Upon

Plea-sure Craft Operators Cards can be obtainedfollowing the completion of a competencycourse, with an on-line option. Details can befound on Transport Canada’s website.www.tc.gc.caEMU33881

Passenger trainingMake sure at least one other passenger istrained to operate the boat in the event of anemergency.EMU33891

Boating safety publicationsBe informed about boating safety. Additionalpublications and information can be obtainedfrom many boating organizations.EMU33591

Laws and regulationsKnow the marine laws and regulations whereyou will be boating- and obey them. Severalsets of rules prevail according to geographiclocation, but all are basically the same as theInternational Rules of the Road. The rulespresented in the following section are con-densed- and have been provided for yourconvenience only.Contact the U.S. Coast Guard, the NationalAssociation of State Boating Law Administra-tors, or your local Power Squadron for a com-plete set of rules governing the waters inwhich you will be using your boat.

Basic boating rules (Rules of the road)

Just as there are rules that apply when youare driving on streets and highways, there arewaterway rules that apply when you are driv-ing your boat. These rules are used interna-tionally. (For U.S.A.: and are also enforced bythe United States Coast Guard and localagencies.) You should be aware of theserules, and follow them whenever you encoun-ter another vessel on the water.EMU33701

Steering and sailing rules and sound signalsWhenever two vessels on the water meet oneanother, one vessel has the right-of-way; it iscalled the “stand-on” vessel. The vessel thatdoes not have the right-of-way is called the“give-way” or “burdened”vessel. These rulesdetermine which vessel has the right-of-way,and what each vessel should do.

Stand-on vesselThe vessel with the right-of-way has the dutyto continue its course and speed, except toavoid an immediate collision. When youmaintain your direction and speed, the othervessel will be able to determine how best toavoid you.

Give-way vesselThe vessel that does not have the right-of-way has the duty to take positive and timelyaction to stay out of the way of the Stand-Onvessel. Normally, you should not cross infront of the vessel with the right-of-way. Youshould slow down or change directions brief-ly and pass behind the other vessel. Youshould always move in such a way that theoperator of the other vessel can see what youare doing.“ The general prudential rule ”This rule is called Rule 2 in the InternationalRules and says,“ In obeying and construing these rules dueregard shall be had to all dangers of naviga-tion and collision, and to any special circum-stances, which may render a departure fromthe above rules necessary in order to avoidimmediate danger.”In other words, follow the standard rules ex-cept when a collision will occur unless bothvessels try to avoid each other. If that is thecase, both vessels become “ Give-Way ” ves-sels.EMU25522

Rules when encountering vesselsThere are three main situations that you mayencounter with other vessels which couldlead to a collision unless the Steering Rulesare followed:Meeting: (you are approaching another ves-sel head-on)

2019 Yamaha M

Safety information

Crossing: (you are traveling across the othervessel’s path)Overtaking: (you are passing or beingpassed by another vessel)In the following illustration, your boat is in thecenter. You should give the right-of-way toany vessels shown in white area (you are theGive-Way vessel). Any vessels in the shadedarea must yield to you (they are the Give-Wayvessels). Both you and the meeting vesselmust alter course to avoid each other.

MeetingIf you are meeting another power vessel headon, and are close enough to run the risk ofcollision, neither of you has the right-of-wayBoth of you should alter course to avoid anaccident. You should keep the other vesselon your port (left) side. This rule doesn’t applyif both of you will clear one another if you con-tinue on your set course and speed.

CrossingWhen two power driven vessels are crossingeach other’s path close enough to run the riskof collision, the vessel which has the other onthe starboard (right) side must keep out of theway of the other. If the other vessel is on yourright, you must keep out of its way; you arethe Give-Way vessel. If the other vessel is onyour port (left) side, remember that youshould maintain course and direction, provid-ed the other vessel gives you the right-of-wayas it should.

OvertakingIf you are passing another vessel, you are the“Give-Way” vessel. This means that the othervessel is expected to maintain its course andspeed. You must stay out of its way until youare clear of it. Likewise, if another vessel ispassing you, you should maintain your speedand direction so that the other vessel cansteer itself around you.EMU25532

Other special situationsThere are three other rules you should beaware of when driving your boat around othervessels.Narrow channels and bendsWhen navigating in narrow channels, youshould keep to the right when it is safe andpractical to do so. If the operator of a power-driven vessel is preparing to go around abend that may obstruct the view of other wa-

2019 Yamaha M

ter vessels, the operator should sound a pro-longed blast on the whistle (4 to 6 seconds).If another vessel is around the bend, it tooshould sound the whistle. Even if no reply isheard, however, the vessel should still pro-ceed around the bend with caution. If younavigate such waters with your boat, you willneed to carry a portable air horn, availablefrom local marine supply stores.Fishing vessel right-of-wayAll vessels that are fishing with nets, lines ortrawls are considered to be “fishing vessels”under the International Rules. Vessels withtrolling lines are not considered fishing ves-sels. Fishing vessels have the right-of-wayregardless of position. Fishing vessels can-not, however, impede the passage of othervessels in narrow channels.Sailing vessel right-of-waySailing vessels should normally be given theright-of-way. The exceptions to this are:1. When the sailing vessel is overtaking the

power-driven vessel, the power-drivenvessel has the right-of-way.

2. Sailing vessels should keep clear of anyfishing vessel.

3. In a narrow channel, a sailing vesselshould not hamper the safe passage of apower-driven vessel that can navigateonly in such a channel.

Reading buoys and other markersThe waters of the United States are markedfor safe navigation by the lateral system ofbuoyage. Simply put, buoys and markershave an arrangement of shapes, colors, num-bers and lights to show which side of thebuoy a boater should pass on when navigat-ing in a particular direction. The markings onthese buoys are oriented from the perspec-tive of being entered from seaward (the boat-er is going towards the port). This means that

red buoys are passed on the starboard (right)side when proceeding from open water intoport, and black buoys are to port (left) side.When navigating out of port, your positionwith respect to the buoys should be reversed;red buoys should be to port and black buoysto starboard.Many bodies of water used by boaters areentirely within the boundaries of a particularstate. The Uniform State Waterway MarkingSystem has been devised for these waters.This system uses buoys and signs with dis-tinctive shapes and colors to show regulatoryor advisory information. These markers arewhite with black letters and orange boarders.They signify speed zones, restricted areas,danger areas, and general information.Remember, markings may vary by geograph-ic location. Always consult local boating au-thorities before driving your boat in unfamiliarwaters.

Mounting outboard motor

WARNINGEWM02501

Improper mounting of the outboard mo-tor could result in hazardous conditionssuch as poor handling, loss of control,or fire hazards.

Because the outboard motor is veryheavy, special equipment and training isrequired to mount it safely.

Your dealer or other person experienced inproper rigging should mount the outboardmotor using correct equipment and completerigging instructions. For further information,see page 46.EMU33582

Remote control requirements

WARNINGEWM01581

If the engine starts in gear, the boat canmove suddenly and unexpectedly, pos-sibly causing a collision or throwingpassengers overboard.

If the engine ever starts in gear, thestart-in-gear protection device is notworking correctly and you should dis-continue using the outboard. Contactyour Yamaha dealer.

The remote control unit must be equippedwith a start-in-gear protection device(s). Thisdevice prevents the engine from starting un-less it is in neutral.EMU25695

Multiple batteriesTo connect multiple batteries, such as formultiple engine configurations or for an ac-cessory battery, consult your Yamaha dealerabout battery selection and correct wiring.EMU41602

Propeller selectionNext to selecting an outboard motor, select-ing the right propeller is one of the most im-portant purchasing decisions a boater canmake. The type, size, and design of your pro-peller have a direct impact on acceleration,top speed, fuel economy, and even enginelife. Yamaha designs and manufactures pro-pellers for every Yamaha outboard motor andevery application.Your Yamaha dealer can help you select theright propeller for your boating needs. Selecta propeller that will allow the engine to reachthe middle or upper half of the operatingrange at full throttle with the maximum boat-load. Generally, select a larger pitch propellerfor a smaller operating load and a smallerpitch propeller for a heavier load. If you carryloads that vary widely, select the propellerthat lets the engine run in the proper range foryour maximum load but remember that youmay need to reduce your throttle setting tostay within the recommended engine speedrange when carrying lighter loads.Yamaha recommends to use a propeller suit-able for the “Shift Dampener System (SDS)”.For further information, consult your Yamahadealer.To check the propeller, see page 80.

EMU36312

Counter rotation modelsStandard outboard motors rotate clockwise.Counter rotation models rotate counterclock-wise and are typically used in multiple motorsetups.On counter rotation models, be sure to use apropeller intended for counterclockwise rota-tion. These propellers are identified with theletter “L” after the size indication on the pro-peller. WARNING! Never use a standardpropeller with a counter rotation motor, ora counter rotation propeller with a stan-dard motor. Otherwise the boat could goin the direction opposite of that expected(for example, reverse instead of forward),which could lead to an accident. [EWM01811]

For instructions on propeller removal and ins-tallation, see page 80 and 81.EMU25771

Start-in-gear protectionYamaha outboard motors or Yamaha-ap-proved remote control units are equippedwith start-in-gear protection device(s). Thisfeature permits the engine to be started onlywhen it is in neutral. Always select neutral be-fore starting the engine.

GasolineUse a good quality gasoline that meets theminimum octane requirement. If knocking orpinging occurs, use a different brand of gas-oline or premium unleaded fuel. Yamaha rec-ommends that you use alcohol-free gasoline(see Gasoline with Ethanol) whenever possi-ble.The use of a poor quality gasoline may resultin starting and running problems. If you en-counter drivability problems, which you sus-pect could be related to the fuel you areusing, we recommend that you switch to arecognized high quality brand of gasoline,such as a gasoline that is advertised as TopTier Detergent Gasoline. (North America only)Failure to comply with these recommenda-tions may also result in unscheduled mainte-nance, fuel system damage, and internalengine damage.

NOTICEECM01982

Do not use leaded gasoline. Leadedgasoline can seriously damage the en-gine.

Avoid getting water and contaminants inthe fuel tank. Contaminated fuel cancause poor performance or engine dam-age. Use only fresh gasoline that hasbeen stored in clean containers.

Gasoline with EthanolTwo types of gasoline are commonly avail-able in the U.S.A., Canada, Australia andNew Zealand for use in automobiles andboats: conventional gasoline without Ethanoland gasoline with Ethanol, which is typically

referred to as E10 gasoline. According to fed-eral regulations, E10 gasoline may contain upto 10% Ethanol.A high quality gasoline without Ethanol is thepreferred fuel for your Yamaha outboard mo-tor. However, if gasoline with Ethanol is theonly fuel available in your area, your Yamahaoutboard motor is calibrated to run properlyon fresh E10 gasoline that meets the mini-mum octane requirement specified for thismodel.

NOTICEECM02402

Never use a gasoline for your outboardmotor that contains more than 10% Etha-nol, such as E15 which contains 15% Eth-anol or E85 which contains 85% Ethanol,or gasoline containing any amount ofMethanol. These fuels can cause startingand running problems, as well as seriousfuel system and internal engine damage.

Gasoline containing ethanol has severalproperties that may cause boat fuel systemproblems. Ethanol is a strong solvent (cleaning agent)

that can clean gum and varnish depositsfrom a boat’s fuel system, particularly inolder boats, as well as tanks and pipesused in gasoline distribution. These re-leased deposits contaminate the fuel andcan cause problems, such as clogged fuelfilters, carburetors, or fuel injectors, whichcould result in engine damage.

Ethanol may dissolve resins used in theconstruction of fiberglass fuel tanks. Thedissolved resins contaminate the fuel andcan cause problems, such as clogged fuelfilters, carburetors, or fuel injectors, whichcould result in engine damage.

Ethanol is hygroscopic (has a strong at-traction to water). Therefore, any water thatinadvertently enters the fuel system, in-cluding moisture that is absorbed from theair, will mix with the ethanol in the gasoline.If the amount of water is excessive, the eth-anol and water mixture will separate fromthe gasoline in a layer at the bottom of thefuel tank. This ethanol and water mixture isvery corrosive to aluminum fuel tanks andfuel system components.

The usable life span of E10 gasoline maybe shorter than the normal length of off-season boat storage, causing starting andrunning problems related to stale fuel.

For more information on using fuel containingethanol, visit: http://www.yamaha-mo-tor.comGasoline FiltrationYamaha outboard motors are equipped withinternal fuel filters. However, excessive wateror debris entering your engine’s fuel systemcould prematurely clog the internal filters,causing starting and running problems, fuelsystem damage, and internal engine dam-age. Therefore, it is recommended that an ex-ternal 10-micron water-separating fuel filterbe installed on your boat and serviced fre-quently. Consult your authorized Yamahadealer for a 10-micron filter that meets yourengine’s requirements.EMU41342

Gasoline AdditivesGasoline blends change to meet automobileemission regulations and economic condi-tions. Additives, added by gasoline distribu-tors, necessary for proper automobile engineoperation and durability, may not be suffi-cient for typical boat applications. Intakevalve and combustion chamber depositsmay accumulate in boat engines more rapidlythan encountered in automotive use. In addi-

tion, gasoline used for boating will typicallyage longer between refills than gasoline usedin automobiles, resulting in stale and unus-able gasoline that may cause starting andrunning problems, fuel system damage, andinternal engine damage.Yamaha recommends the use of two Yama-lube gasoline additives to reduce internal de-posits and extend the storage life of gasoline.Continuous use of Yamalube Ring Free FuelAdditive Plus reduces harmful internal de-posits. Yamalube Fuel Stabilizer & Condition-er Plus added to fresh gasoline will helpprotect the fuel system from varnishing whilehelping to keep the gasoline’s octane levelfrom decreasing excessively during storage.Other additives may also be available on themarket that may have varying degrees of ef-fectiveness. Consult your Yamaha dealerconcerning what may work best for the local-ly available gasoline and environmental con-ditions.EMU41351

Anti-fouling paintA clean hull is required to maintain yourboat’s performance. Boats moored in the wa-ter should be protected from marine growth(barnacles, mussels, and marine plants). Ifapproved by regulations for your area, thebottom of the hull can be coated with an anti-fouling paint to inhibit marine growth.Anti-fouling paints specifically formulated foruse on aluminum may be applied to the out-board motor. The original Yamaha paint sur-face may be scuffed lightly before applyinganti-fouling paint, but do not remove the orig-inal paint. Removal of the original paint will in-crease the rate of corrosion.

If twin engines are installed on your boat, thegauge will only display the total fuel economyof both engines. Fuel consumption varies greatly with boat

design, weight, propeller used, engine trimangle, sea conditions (including wind), andthrottle position. Fuel consumption alsovaries slightly with the type of water (salt,fresh, and contaminate levels), air temper-ature and humidity, cleanliness of the boatbottom, engine mounting height, skill of theoperator, and individual gasoline formula-tion (winter or summer fuel and amount ofadditives).

The Yamaha digital speedometer and fuelmanagement meter calculates speed,miles traveled, and fuel economy by watermovement at the stern of the boat. This dis-tance can vary greatly from the actual dis-tance traveled because of water currents,sea swells, and the condition of the waterspeed sensor (if partially plugged or dam-aged).

Individual engines may slightly vary in theirfuel consumption due to manufacturingvariations. These variations can be evengreater if the engines are of different yearmodels. In addition, variations in propel-lers, even of the same basic dimensions ofthe same design, can also cause a slightvariation in fuel consumption.

EMU26783

Twin-engine speed synchronizerThis gauge displays the difference in enginespeed (r/min) between the port and starboardengines for reference purposes when syn-chronizing the two engines’ speeds.

If the two engines’ speeds are not synchro-nized while cruising, adjusting trim angle orthrottle can synchronize them.If large differences in trim angle or throttle areneeded to synchronize the engines, consultyour Yamaha dealer for adjustments to thethrottle cables.

EMU26903

InstallationThe information presented in this section isintended as reference only. It is not possibleto provide complete instructions for everypossible boat and motor combination. Propermounting depends in part on experience andthe specific boat and motor combination.

WARNINGEWM01591

Overpowering a boat could cause se-vere instability. Do not install an out-board motor with more horsepowerthan the maximum rating on the capaci-ty plate of the boat. If the boat does nothave a capacity plate, consult the boatmanufacturer.

Improper mounting of the outboard mo-tor could result in hazardous conditionssuch as poor handling, loss of control,or fire hazards. For permanently mount-ed models, your dealer or other personexperienced in proper rigging shouldmount the motor.

EMU33482

Mounting the outboard motorThe outboard motor should be mounted sothat the boat is well balanced. Otherwise, theboat could be hard to steer. For single-engineboats, mount the outboard motor on the cen-terline (keel line) of the boat. For twin engineboats, mount the outboard motors equidis-tant from the centerline. Consult yourYamaha dealer or boat manufacturer for fur-ther information on determining the propermounting location.

EMU26935

Mounting height (boat bottom)The mounting height of your outboard motoraffects its efficiency and reliability. If it ismounted too high, propeller ventilation mayoccur, which will reduce propulsion due toexcessive propeller slip, and the water in-takes for the cooling system may not get ad-equate water supply, which can cause engineoverheating. If the engine is mounted too low,water resistance (drag) will increase, therebyreducing engine efficiency and performance.Most commonly, outboard motor should bemounted so that the anti-cavitation plate is inalignment with the bottom of the boat. Theoptimum mounting height of the outboardmotor is affected by the boat/motor combi-nation and the desired use. Test runs at dif-ferent heights can help determine theoptimum mounting height. Consult your

Yamaha dealer or boat manufacturer for fur-ther information on determining the propermounting height.

NOTICEECM01635

Make sure that the idle hole is highenough to prevent water from enteringthe engine even if the boat is stationarywith the maximum load.

Incorrect engine height or obstructionsto the smooth flow of water (such as thedesign or condition of the boat, or ac-cessories, such as transom ladders ordepth finder transducers) can create air-borne water spray while the boat iscruising. If the outboard motor is oper-ated continuously in the presence of air-borne water spray, enough water couldenter the engine through the air intakeopening in the top cowling to cause se-vere engine damage. Remove the causeof the airborne water spray.

Fill engine oilThe engine is shipped from the factory with-out engine oil. If your dealer did not fill the oil,you must fill it before starting the engine.NOTICE: Check that the engine is filledwith oil before first-time operation to avoidsevere engine damage. [ECM01782]

The engine is shipped with the following tag,which should be removed after engine oil isfilled for the first time. For more informationon checking the engine oil level, see page 50.

EMU30175

Breaking in engineYour new engine requires a period of break-in to allow mating surfaces of moving parts towear in evenly. Correct break-in will help en-sure proper performance and longer enginelife. NOTICE: Failure to follow the break-inprocedure could result in reduced enginelife or even severe engine damage. [ECM00802]

EMU27086

Procedure for 4-stroke modelsYour new engine requires a period of 10hours break-in to allow mating surfaces ofmoving parts to wear in evenly.

TIP:Run the engine in the water, under load (ingear with a propeller installed) as follows. For10 hours for breaking in engine avoid extend-ed idling, rough water and crowded areas.1. For the first hour of operation:

Run the engine at varying speeds up to2000 r/min or approximately half throttle.

2. For the second hour of operation:Increase engine speed as much as nec-essary to put the boat on plane (butavoid full-throttle operation), then backoff on the throttle while keeping the boatat a planing speed.

3. Remaining 8 hours:Run the engine at any speed. However,avoid operating at full throttle for morethan 5 minutes at a time.

4. After the first 10 hours:Operate the engine normally.

Trimming outboard motor

WARNINGEWM00741

Excessive trim for the operating condi-tions (either trim up or trim down) can cau-se boat instability and can make steeringthe boat more difficult. This increases thepossibility of an accident. If the boat be-gins to feel unstable or is hard to steer,slow down and/or readjust the trim angle.

The trim angle of the outboard motor helpsdetermine the position of the bow of the boatin the water. Correct trim angle will help im-prove performance and fuel economy whilereducing strain on the engine. Correct trimangle depends upon the combination ofboat, engine, and propeller. Correct trim isalso affected by variables such as the load inthe boat, sea conditions, and running speed.

EMU27889

Adjusting trim angle (Power trim and tilt)

WARNINGEWM00754

Be sure all people are clear of the out-board motor when adjusting the trim an-gle. Body parts can be crushed betweenthe motor and the clamp bracket whenthe motor is trimmed or tilted.

Use caution when trying a trim positionfor the first time. Increase speed gradu-ally and watch for any signs of instabilityor control problems. Improper trim an-gle can cause loss of control.

If equipped with a power trim and tiltswitch located on the bottom cowling,use the switch only when the boat is at acomplete stop with the engine off. Donot adjust the trim angle with this switchwhile the boat is moving.

Adjust the outboard motor trim angle usingthe power trim and tilt switch.

To raise the bow (trim-out), press the switch“ ” (up).To lower the bow (trim-in), press the switch“ ” (down).Make test runs with the trim set to differentangles to find the position that works best foryour boat and operating conditions.EMU27913

Adjusting boat trimWhen the boat is on plane, a bow-up attituderesults in less drag, greater stability and effi-ciency. This is generally when the keel line ofthe boat is up about 3 to 5 degrees. With thebow up, the boat may have a greater tenden-cy to steer to one side or the other. Compen-sate for this as you steer. When the bow ofthe boat is down, it is easier to acceleratefrom a standing start onto plane.

Bow UpToo much trim-out puts the bow of the boattoo high in the water. Performance and econ-omy are decreased because the hull of theboat is pushing the water and there is moreair drag. Excessive trim-out can also causethe propeller to ventilate, which reduces per-formance further, and the boat may “por-poise” (hop in the water), which could throwthe operator and passengers overboard.

Bow DownToo much trim-in causes the boat to “plow”through the water, decreasing fuel economyand making it hard to increase speed. Oper-ating with excessive trim-in at higher speedsalso makes the boat unstable. Resistance atthe bow is greatly increased, heightening thedanger of “bow steering” and making opera-tion difficult and dangerous.

Transporting and storing out-board motor

WARNINGEWM02641

USE CARE when transporting fuel tank,whether in a boat or car.

DO NOT fill fuel container to maximumcapacity. Gasoline will expand consider-ably as it warms up and can build uppressure in the fuel container. This cancause fuel leakage and a potential firehazard.

Leaking fuel is a fire hazard. Tighten se-curely the fuel valve when transportingand storing the outboard motor.

Never get under the outboard motorwhile it is tilted. Severe injury could oc-cur if the outboard motor accidentallyfalls.

Do not use the tilt support lever or knobwhen trailering the boat. The outboardmotor could shake loose from the tiltsupport and fall. If the outboard motorcannot be trailered in the normal run-ning position, use an additional supportdevice to secure it in the tilt position.

Leaking fuel is a fire hazard. When traileringthe boat, close the fuel valve to prevent fuelfrom leaking.The outboard motor should be transportedand stored in the normal running position. Ifthere is insufficient road clearance in this po-sition, then trailer the outboard motor in thetilt position using a motor support devicesuch as a transom saver bar. Consult yourYamaha dealer for further details.When the outboard motor is tilted prolongedtime for mooring or trailering the boat, closethe fuel valve.

EMU30722

Storing outboard motorWhen storing your Yamaha outboard motorfor prolonged periods of time (2 months orlonger), several important procedures mustbe performed to prevent excessive damage.It is advisable to have your outboard motorserviced by an authorized Yamaha dealer pri-or to storage. However, you, the owner, witha minimum of tools, can perform the follow-ing procedures.

NOTICEECM01361

To prevent problems which can becaused by oil entering the cylinder fromthe sump, keep the outboard motor inthe attitude shown when transportingand storing it. Do not store or transportthe outboard motor on its side (not up-right).

Do not place the outboard motor on itsside before the cooling water hasdrained from it completely, otherwisewater may enter the cylinder through theexhaust port and cause engine trouble.

Store the outboard motor in a dry, well-ventilated place, not in direct sunlight.

Conditioning and stabilizing gasolineWhen preparing to store a boat for extendedperiods (2 months or longer) it is best to com-pletely remove all gasoline from the boat’sfuel tank(s). If it is not possible to remove thegasoline, add one ounce of “Yamalube FuelStabilizer & Conditioner Plus” to each gallonof gasoline in a full tank of gasoline to providefuel stability and corrosion protection.

TIP:Do not fill the fuel tank(s) to the point of over-flowing. Approximately 7/8 full will allowenough space in the fuel tank to prevent gas-oline purging from the fuel tank vent due toexpansion with temperature changes.Do not cap the fuel tank vent. Excessivepressure could damage the boat and motor’sfuel systems.A partially filled fuel tank, less than 7/8 full butnot completely empty, is not recommended.Air space above the gasoline allows airmovement which can bring in water throughcondensation as the air temperature chang-es.Condensation inside the fuel tank can causecorrosion problems and phase separation ofgasoline containing ethanol.

Consult your Yamaha dealer concerning pre-ventative measures that may work best forthe gasoline and environmental conditions inyour area.EMU28306

Cleaning and adjusting spark plugThe spark plug is an important engine com-ponent and is easy to inspect. The conditionof the spark plug can indicate somethingabout the condition of the engine. For exam-ple, if the center electrode porcelain is verywhite, this could indicate an intake air leak orcarburetion problem in that cylinder. Do notattempt to diagnose any problems yourself.Instead, take the outboard motor to aYamaha dealer. You should periodically re-move and inspect the spark plug becauseheat and deposits will cause the spark plug toslowly break down and erode.1. Remove the bolts to remove the ECM

(Electronic control module) cover.

2. Remove the bolts that are securing theignition coil, and then remove the ignitioncoil. Do not use any tools to remove orinstall the ignition coil, otherwise the igni-tion coil coupler may get damaged.

3. Remove the spark plug. If electrode ero-sion becomes excessive, or if carbonand other deposits are excessive, youshould replace the spark plug with an-other of the correct type. WARNING!When removing or installing a sparkplug, be careful not to damage the in-sulator. A damaged insulator could al-low external sparks, which could leadto explosion or fire. [EWM00562]

4. Be sure to use the specified spark plug,otherwise the engine may not operateproperly. Before fitting the spark plug,measure the electrode gap with a wirethickness gauge; replace it if out of spec-ification.

5. When fitting the plug, wipe off any dirtfrom the threads, and then screw it in tothe correct torque.

TIP:If a torque-wrench is not available when youare reinstalling a spark plug, a good estimateof the correct torque is 1/12 turn past finger-tight. When you are installing a new sparkplug, a good estimate of the correct torque is1/2 to 2/3 turn past finger-tight.6. Install the ignition coil and tighten the

bolts.

7. Install the ECM (Electronic control mod-ule) cover and tighten the bolts.

Inspecting idle speed

WARNINGEWM00452

Do not touch or remove electrical partswhen starting or during operation.

Keep hands, hair, and clothes awayfrom the flywheel and other rotatingparts while the engine is running.

NOTICEECM00491

This procedure must be performed whilethe outboard motor is in the water. A flush-ing attachment or test tank can be used.

If the boat is not equipped with a tachometerfor the outboard motor, use a diagnostic ta-chometer for this procedure. Results mayvary depending on whether testing is con-ducted with the flushing attachment, in a testtank, or with the outboard motor in the water.1. Start the engine and allow it to warm up

fully in neutral until it is running smoothly.2. Once the engine has warmed up, verify

whether the idle speed is set to specifi-cation. For idle speed specifications, seepage 13. If you have difficulty verifyingthe idle speed, or the idle speed requiresadjustment, consult a Yamaha dealer orother qualified mechanic.

IMPORTANT WARRANTY INFORMATION IF YOU USE YOUR YAMAHA OUTSIDE THE U.S.A. OR CANADA

Welcome to the Yamaha Family!

Congratulations on the purchase of your new Yamaha products. Yamaha is commit-ted to exceptional customer satisfaction and we want your ownership experience to be a satisfying one. Please read the following warranty information to help ensure satisfaction with your Yamaha.

This model was manufactured with specifications appropriate for sale and use in the U.S.A. and Canada. Please note the following information:

Your Yamaha model may not be sold in some countries. Therefore, a Yamaha dealer outside the United States or Canada may not have all of the replacement parts or technical information available to provide proper service. This may unavoidably delay repairs. Thank you for your understanding should this happen.

TIP:

1. As explained in the Limited Warranty Statement, the Yamaha warranty covers your Yamaha when it is registered and used in your country of residence. If you are temporarily using a U.S.-registered outboard motor in Canada, or a Canada-registered outboard motor in the United States, and it needs warranty repairs, you should contact a nearby authorized Yamaha Outboard Motor Dealer for assistance. The local dealer will contact Yamaha on the owner’s behalf so that needed repairs can be made as quickly as possible.

2. If you need repairs while temporarily using your Yamaha in another country, contact the local authorized Yamaha distributor for that country. Yamaha will work with that distributor to make the needed repairs as quickly as possible. If you have to pay for a repair that you believe your warranty would have covered at home, present all repair orders, receipts, or other related documents to your local dealer when you return home. He will be able to contact Yamaha on your behalf to see if any refund can be provided.

3. If your Yamaha is registered or used primarily outside the United States or Canada, the warranty printed in this manual does not apply to you. Contact the dealer who sold the Yamaha marine power unit to you for customer support information.
