Safety information

EMU33621

Safety information

Observe these precautions at all times.

EMU33630

Rotating parts

Hands, feet, hair, jewelry, clothing, PFDstraps, etc. can become entangled with inter-nal rotating parts of the engine, resulting inserious injury or death.Keep the top cowling in place whenever pos-sible. Do not remove or replace the cowlingwith the engine running.Only operate the engine with the cowling re-moved according to the specific instructionsin the manual. Keep hands, feet, hair, jewel-ry, clothing, PFD straps, etc. away from anyexposed moving parts.

EMU33640

Hot parts

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

EMU33650

Electric shock

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

EMU33660

Power trim and tilt

Body 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 thisarea before operating the power trim and tiltmechanism.The power trim and tilt switches operateeven when the main switch is off. Keep peo-ple be away from the switches wheneverworking around the motor.Never get under the lower unit while it is tilt-ed, even when the tilt support lever is locked.

Severe injury could occur if the outboard mo-tor accidentally falls.

EMU33670

Engine shut-off cord

Attach the engine shut-off cord so that theengine stops if the operator falls overboardor leaves the helm. This prevents the boatfrom running away under power and leavingpeople stranded, or running over people orobjects.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.

EMU33810

Gasoline

Gasoline and its vapors are highly flam-mable and explosive.

Always, refuel ac-cording to the procedure on page 48 toreduce the risk of fire and explosion.

EMU33820

Gasoline exposure and spills

Take 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.

EMU33900

Carbon monoxide

This product emits exhaust gases whichcontain carbon monoxide, a colorless, odor-less gas which may cause brain damage ordeath when inhaled. Symptoms include nau-sea, dizziness, and drowsiness. Keep cock-pit and cabin areas well ventilated. Avoidblocking exhaust outlets.

EMU33780

Modifications

Do 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.

EMU33740

Boating safety

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

EMU33710

Alcohol and drugs

Never operate after drinking alcohol or tak-ing drugs. Intoxication is one of the mostcommon factors contributing to boating fatal-ities.

EMU33720

Personal flotation devices

Have an approved personal flotation device(PFD) on board for every occupant. Yamaharecommends that you must wear a PFDwhenever boating. At a minimum, childrenand non-swimmers should always wearPFDs, and everyone should wear PFDswhen there are potentially hazardous boat-ing conditions.

EMU33730

People in the water

Always watch carefully for people in the wa-ter, such as swimmers, skiers, or divers,whenever the engine is running. Whensomeone is in the water near the boat, shift

into neutral and shut off the motor.Stay away from swimming areas. Swimmerscan be hard to see.The propeller can keep moving even whenthe motor is in neutral. Shut off the enginewhen a person is in the water near you.

EMU33750

Passengers

Consult your boat manufacturer’s instruc-tions for details about appropriate passengerlocations in your boat and be sure all pas-sengers are positioned properly before ac-celerating 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.

EMU33760

Overloading

Do not overload the boat. Consult the boatcapacity plate or boat manufacturer for max-imum weight and number of passengers. Besure that weight is properly distributed ac-cording to the boat manufacturers instruc-tions. Overloading or incorrect weightdistribution can compromise the boats han-dling and lead to an accident, capsizing orswamping.

EMU33770

Avoid collisions

Scan constantly

for people, objects, andother boats. Be alert for conditions that limityour visibility or block your vision of others.

Operate defensively

at safe speeds andkeep a safe distance away from people, ob-jects, and other boats.

�

Do not follow directly behind other boats orwaterskiers.

Safety information

7

�

Avoid sharp turns or other maneuvers thatmake 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 lossof control, 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 arenot sure that you can stop in time beforehitting an obstacle, apply throttle and turnin another direction.

EMU33790

Weather

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

EMU33800

Accident reporting

Boat operators are required by law to file aBoating Accident Report with their stateboating law enforcement agency if their boatis involved 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.

EMU33870

Boat education and training

Operators should take a boating safetycourse. This may be required in your state.Many of the organizations listed in the nextsection can provide information about cours-es in your 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. Uponsuccessful completion of the course, theuser can download a certificate of comple-tion immediately or, for a small charge, re-quest one by mail. To take this free course,go to boatus.org.

EMU33880

Passenger training

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

EMU33890

Boating safety publications

Be informed about boating safety. Additionalpublications and information can be obtainedfrom many boating organizations.

EMU33590

Laws and regulations

EMU33690

Basic boating rules (Rules of the road)

Just as there are rules that apply when youare driving on streets and highways, thereare waterway rules that apply when you aredriving your boat. These rules are used inter-nationally. (For USA: and are also enforcedby the United States Coast Guard and localagencies.) You should be aware of theserules, and follow them whenever you en-counter another vessel on the water.

EMU33700

Steering and sailing rules and sound signals

Whenever two vessels on the water meetone another, one vessel has the right-of-way; it is called the “stand-on” vessel. Thevessel that does not have the right-of-way iscalled the “give-way” or “burdened”vessel.These rules determine which vessel has theright-of-way, and what each vessel shoulddo.

Stand-on vessel

The 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 vessel

The 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-On

Safety information

vessel. 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 whatyou are 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 ”vessels.

EMU25521

Rules when encountering vessels

There 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)

Crossing:

(you are traveling across the oth-er vessel’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 shad-ed area must yield to you (they are the Give-Way vessels). Both you and the meetingvessel must alter course to avoid each other.

Meeting

If you are meeting another power vesselhead on, and are close enough to run the riskof collision, neither of you has the right-of-way Both of you should alter course to avoidan accident. You should keep the other ves-sel on your port (left) side. This rule doesn’tapply if both of you will clear one another ifyou continue on your set course and speed.

Crossing

When two power driven vessels are crossingeach other’s path close enough to run therisk of collision, the vessel which has the oth-er on the starboard (right) side must keep outof the way of the other. If the other vessel ison your right, you must keep out of its way;you are the Give-Way vessel. If the othervessel is on your port (left) side, rememberthat you should maintain course and direc-tion, provided the other vessel gives you theright-of-way as it should.

Safety information

10

Overtaking

If you are passing another vessel, you arethe “Give-Way” vessel. This means that theother vessel is expected to maintain itscourse and speed. You must stay out of itsway until you are clear of it. Likewise, if an-other vessel is passing you, you shouldmaintain your speed and direction so that theother vessel can steer itself around you.

EMU25531

Other special situations

There are three other rules you should beaware of when driving your boat around oth-er vessels.

Narrow channels and bends

When 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-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-way

All vessels that are fishing with nets, lines or

trawls 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-way

Sailing 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-driv-en vessel 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 ofa power-driven vessel that can navigateonly in such a channel.

Reading buoys and other markers

The waters of the United States are markedfor safe navigation by the lateral system ofbuoyage. Simply put, buoys and markershave an arrangement of shapes, colors,numbers 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 thatred buoys are passed on the starboard(right) side when proceeding from open wa-ter into port, and black buoys are to port (left)side. When navigating out of port, your posi-tion with respect to the buoys should be re-versed; red buoys should be to port andblack buoys to 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.

Safety information

11

This system uses buoys and signs with dis-tinctive shapes and colors to show regulato-ry or advisory information. These markersare white with black letters and orangeboarders. They signify speed zones, restrict-ed areas, danger areas, and general infor-mation.Remember, markings may vary by geo-graphic location. Always consult local boat-ing authorities before driving your boat inunfamiliar waters.

ECM00010

Use only new clean gasoline which hasbeen stored in clean containers and is notcontaminated with water or foreign mat-

ter.

EMU33960

Gasoline

If knocking or pinging occurs, use a different

brand of gasoline or premium unleaded fuel.

Gasohol

There are two types of gasohol: gasohol con-taining ethanol and that containing metha-nol. Gasohol containing ethanol can be usedif ethanol content does not exceed 10% andthe fuel meets minimum octane ratings. E-85is a fuel blend containing 85% ethanol andtherefore must not be used in your outboardmotor. All ethanol blends containing morethan 10% ethanol can cause fuel systemdamage or engine performance problems.Yamaha does not recommend gasohol-con-taining methanol because it can cause fuelsystem damage or engine performanceproblems.

EMU25660

Engine oil

Use Yamalube 2-M outboard oil. If Ya-malube 2-M is not available, use only anoth-er outboard motor manufacturer’s factory-brand oil with TC-W3 rating.

CAUTION:

ECM01290

Serious engine damage can result fromthe use of lower quality oil, includingsome commonly available oil brands with“TC-W3” on their label. To avoid the risk,use only Yamalube 2-M or, if necessary,another outboard motor manufacturer’s

factory-brand TC-W3 oil.

Recommended gasoline:Regular unleaded gasoline with a min-imum octane rating of 86 (Pump Oc-tane Number) = (R+M)/2

WARNING

EWM01560

Overpowering a boat can cause severe

instability.

EMU33570

Mounting motor

Your dealer or other person experienced inproper rigging should mount the motor usingcorrect equipment and complete rigging in-structions. For further information, see page41.

WARNING

EWM01570

�

Improper mounting of the outboard mo-tor could result in hazardous condi-tions such as poor handling, loss ofcontrol, or fire hazards.

�

Because the motor is very heavy, spe-cial equipment and training is required

to mount it safely.

EMU33580

Remote control requirements

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.

WARNING

EWM01580

�

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

passengers overboard.

�

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

your Yamaha dealer.

EMU25702

Battery requirement

CAUTION:

ECM01061

Do not use a battery that does not meetthe specified capacity. If a battery thatdoes not meet specifications is used, theelectric system could perform poorly orbe overloaded, causing electric system

damage.

For electric start models, choose a batterywhich meets the following specifications.

every application.Your outboard motor came with a Yamahapropeller chosen to perform well over arange of applications, but there may be useswhere a different propeller would be moreappropriate.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, chose a larger pitch propel-ler for a smaller operating load and a smallerpitch propeller for a heavier load. If you carryloads that vary widely, chose the propellerthat lets the engine run in the proper rangefor your maximum load but remember thatyou may need to reduce your throttle settingto stay within the recommended enginespeed range when carrying lighter loads.For instructions on propeller removal and in-stallation, see page 72.

EMU25770

Installation

The information presented in this section isintended as reference only. It is not possibleto provide complete instructions for everypossible boat and motor combination. Prop-er mounting depends in part on experienceand the specific boat and motor combination.

WARNING

EWM01590

�

Overpowering a boat could cause se-vere instability. Do not install an out-board motor with more horsepowerthan the maximum rating on the capac-ity 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 condi-tions such as poor handling, loss ofcontrol, or fire hazards. For permanent-ly mounted models, your dealer or oth-er person experienced in proper

rigging should mount the motor.

EMU33480

Mounting the outboard motor

The outboard motor should be mounted sothat the boat is well balanced. Otherwise, theboat could be hard to steer. For single-en-gine boats, mount the outboard motor on thecenterline (keel line) of the boat. For dual en-gine boats, mount the outboard motors equi-distant from the centerline. Consult yourYamaha dealer or boat manufacturer for fur-ther information on determining the propermounting location.

EMU26931

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 causeengine overheating. If the engine is mountedtoo low, water resistance (drag) will in-crease, thereby reducing engine efficiencyand 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 outboard

motor is affected by the boat/motor combina-tion and the desired use. Test runs at differ-ent heights can help determine the optimummounting height. Consult your Yamaha deal-er or boat manufacturer for further informa-tion on determining the proper mountingheight.

CAUTION:

ECM01630

�

During water testing, check the buoy-ancy of the boat, at rest, with its maxi-mum load. Check that the static waterlevel on the exhaust housing is lowenough to prevent water entry into thepower head when water rises due towaves when the outboard is not run-ning.

�

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 createairborne water spray while the boat iscruising. If the motor is operated con-tinuously in the presence of airbornewater spray, enough water could enterthe engine through the intake openingon the cowling to cause severe enginedamage. Eliminate the cause of the air-

borne water spray.

EMU27041

Breaking in engine

Your 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.

CAUTION:

ECM00750

�

Failure to follow the break-in procedurecould result in reduced engine life oreven severe engine damage.

�

Do not use premixed fuel in this enginebecause it could cause carbon depos-its on the fuel injector and engine trou-ble.

Procedure for HPDI models

Run the engine under load (in gear with apropeller installed) for 10 hours as follows.1. First 10 minutes:

Run the engine at the lowest possiblespeed. A fast idle in neutral is best.

2. Next 50 minutes:Do not exceed half throttle (approxi-mately 3000 r/min). Vary engine speedoccasionally. If you have an easy-plan-ing boat, accelerate at full throttle ontoplane, then immediately reduce thethrottle to 3000 r/min or less.

3. Next two hours:Accelerate at full throttle onto plane,then reduce engine speed to three-quar-ter throttle (approximately 4000 r/min).Vary engine speed occasionally. Run atfull throttle for one minute, then allowabout 10 minutes of operation at three-

quarter throttle or less to let the enginecool.

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

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

Ring Free Fuel Additive

Gasoline is a precise blend of many differentsubstances, each chosen to give certaincharacteristics. Gasoline blends have beenchanging in recent years in response to con-cerns about pollution and resulting emis-

sions regulations. One of the most obviouschanges has been the elimination of leadfrom most fuels.As gasoline has changed, the amount of ad-ditives such as aromatics and oxygenateshas increased. These additives are impor-tant for the engines in passenger cars, butthey can have detrimental effects in marineengines, because of increased deposits inthe combustion chamber. When enough de-posits collect, piston rings begin sticking.Performance drops and engine wear in-creases dramatically.While many additives available may reducedeposits, Yamaha recommends the use of

Trimming outboard motor

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.

WARNING

EWM00740

Excessive trim for the operating condi-tions (either trim up or trim down) cancause boat instability and can makesteering the boat more difficult. This in-creases the possibility of an accident. Ifthe boat begins to feel unstable or is hardto steer, slow down and/or readjust the

trim angle.

Adjusting trim angle (Power trim and tilt)

WARNING

EWM00752

�

Be sure all people are clear of the out-board motor when adjusting the tilt an-gle. Body parts can be crushedbetween the motor and the clampbracket when the motor is trimmed ortilted.

�

Use caution when trying a trim positionfor the first time. Increase speed gradu-ally and watch for any signs of instabil-ity or control problems. Improper trimangle 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 ata complete stop with the engine off. Do

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.

EMU27911

Adjusting boat trim

When 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. The trim tab canalso be adjusted to help offset this effect.When the bow of the boat is down, it is easierto accelerate from a standing start ontoplane.

Bow Up

Too 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 Down

Too 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.

NOTE:

Depending on the type of boat, the outboardmotor trim angle may have little effect on the

trim of the boat when operating.

EMU27934

Tilting up and down

If the engine will be stopped for some time orif the boat is moored in shallows, the out-board motor should be tilted up to protect thepropeller and lower casing from damage bycollision with obstructions, and also to re-

duce salt corrosion.

WARNING

EWM00221

Be sure all people are clear of the out-board motor when tilting up and down,Body parts can be crushed between themotor and the clamp bracket when the

motor is trimmed or tilted.

WARNING

EWM00250

Leaking fuel is a fire hazard. If there is afuel joint on the outboard motor, discon-nect the fuel line or close the fuel cock ifthe engine will be tilted for more than a

few minutes. Otherwise fuel may leak.

care so that neither you nor anyone elsegets burnt. To avoid burns, work on the

engine when it has cooled down.

The 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 plugto slowly break down and erode. If electrodeerosion becomes excessive, or if carbon andother deposits are excessive, you should re-place the spark plug with another of the cor-rect type.

Before fitting the spark plug, measure theelectrode gap with a wire thickness gauge;adjust the gap to specification if necessary.

When fitting the plug, always clean the gas-ket surface and use a new gasket. Wipe offany dirt from the threads and screw in thespark plug to the correct torque.

NOTE:

If a torque-wrench is not available when youare fitting a spark plug, a good estimate ofthe correct torque is 1/4 to 1/2 a turn past fin-ger-tight. Have the spark plug adjusted to thecorrect torque as soon as possible with a

torque-wrench.
