Safety information� Before mounting or operating the outboard

motor, read this entire manual. Reading itshould give you an understanding of themotor and its operation.

� Before operating the boat, read any own-er’s or operator’s manuals supplied with itand all labels. Be sure you understand eachitem before operating.

� Do not overpower the boat with this out-board motor. Overpowering the boat couldresult in loss of control. The rated power ofthe outboard should be equal to or less than

the rated horsepower capacity of the boat.If the rated horsepower capacity of the boatis unknown, consult the dealer or boat man-ufacturer.

� Do not modify the outboard. Modificationscould make the motor unfit or unsafe to use.

� Incorrect propeller selection and incorrectuse may not only cause engine damage,but also adversely affect fuel consumption.Consult your dealer for correct use.

� Never operate after drinking alcohol or tak-ing drugs. About 50% of all boating fatalitiesinvolve intoxication.

� Have an approved personal flotation device(PFD) on board for every occupant. It is agood idea to wear a PFD whenever boat-ing. At a minimum, children and non-swim-mers should always wear PFDs, andeveryone should wear PFDs when thereare potentially hazardous boating condi-tions.

� Gasoline is highly flammable, and its va-pors are flammable and explosive. Handleand store gasoline carefully. Make surethere are no gas fumes or leaking fuel be-fore starting the engine.

� This product emits exhaust gases whichcontain carbon monoxide, a colorless,odorless gas which may cause brain dam-age or death when inhaled. Symptoms in-clude nausea, dizziness, and drowsiness.Keep cockpit and cabin areas well ventilat-ed. Avoid blocking exhaust outlets.

� Check throttle, shift, and steering for properoperation before starting the engine.

� Attach the engine stop switch lanyard cordto a secure place on your clothing, or yourarm or leg while operating. If you acciden-tally leave the helm, the cord will pull fromthe switch, stopping the engine.

� Know the marine laws and regulationswhere you will be boating—and obey them.For basic boating rules, see “Rules of theroad” on page 5.

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

� Tell someone where you are going: leave aFloat Plan with a responsible person. Besure to cancel the Float Plan when you re-turn.

� Use common sense and good judgmentwhen boating. Know your abilities, and besure you understand how your boat han-dles under the different boating conditionsyou may encounter. Operate within yourlimits, and the limits of your boat. Alwaysoperate at safe speeds, and keep a carefulwatch for obstacles and other traffic.

� Always watch carefully for swimmers duringthe engine operation.

� Stay away from swimming areas.� When a swimmer is in the water near you

shift into neutral and shut off the engine.� Do not illegally discard empty containers

used to replace or replenish oil. For the cor-rect processing of empty containers, con-sult the dealer where you purchased the oil.

� When replacing oils used to lubricate theproduct (engine or gear oil), be sure to wipeaway any spilt oil. Never pour oil without us-ing a funnel or similar device. If necessary,verify the necessary replacement proce-dure with the dealer.

� Never illegally discard (dump) the product.Yamaha recommends consulting the deal-er on discarding the product.

EMU25500

Basic boating rules (Rules of the road)

Just as there are rules which apply when youare driving on streets and high ways, thereare waterway rules which apply when you aredriving your boat. These rules are used inter-nationally, and are also enforced by the Unit-ed States Coast Guard and local agencies.You should be aware of these rules, and fol-low them whenever you encounter anothervessel on the water.Several sets of rules prevail according to geo-graphic location, but are all basically the sameas the International Rules of the Road. Therules presented here in your Owner’s Manualare condensed, and have been provided foryour convenience only. Consult your localU.S. Coast Guard Auxiliary or Department ofMotor Vehicles for a complete set of rulesgoverning the waters in which you will be us-ing your boat.EMU25510

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 vesselwhich does not have the right-of-way is called

the “give-way” or “burdened” vessel. Theserules determine 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 you main-tain your direction and speed, the other vesselwill be able to determine how best to avoidyou.Give-way vesselThe vessel which 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 in frontof the vessel with the right-of-way. You shouldslow down or change directions briefly andpass behind the other vessel. You should al-ways move in such a way that the operator ofthe other vessel can see what you are doing.“The general prudential rule”This rule is called Rule 2 in the InternationalRules and says,“In obeying and construing these rules due re-gard shall be had to all dangers of navigationand collision, and to any special circumstanc-es, which may render a departure from theabove rules necessary in order to avoid im-mediate 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.EMU25520

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


General 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 of col-lision, neither of you has the right-of-way!Both of you should alter course to avoid an ac-cident. You should keep the other vessel onyour port (left) side. This rule doesn’t apply ifboth 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 are theGive-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.EMU25530

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 water

vessels, the operator should sound a pro-longed blast on the whistle (4 to 6 seconds). Ifanother 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 you nav-igate such waters with your boat, you willneed to carry a portable air horn, availablefrom local marine supply stores.Fishing vessel right-of-wayAll vessels which 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-way re-gardless of position. Fishing vessels cannot,however, impede the passage of other ves-sels 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 which 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 the buoya boater should pass on when navigating in aparticular direction. The markings on thesebuoys are oriented from the perspective of be-ing entered from seaward (the boater is goingtowards the port). This means that red buoysare passed on the starboard (right) side when

proceeding from open water into port, andblack buoys are to port (left) side. When navi-gating out of port, your position with respect tothe buoys should be reversed; red buoysshould be to port and black buoys to star-board.Many bodies of water used by boaters are en-tirely 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.

Battery requirement

CAUTION:ECM01060

Do not use a battery that does not meet thespecified capacity. If a battery which doesnot meet specifications is used, the elec-tric system could perform poorly or beoverloaded, causing electric system dam-age.

For electric start models, choose a batterywhich meets the following specifications.EMU25711

Battery specifications

NOTE:The engine cannot be started if battery volt-age is too low.

EMU25742

Propeller selectionThe performance of your outboard motor willbe critically affected by your choice of propel-ler, as an incorrect choice could adversely af-fect performance and could also seriously

damage the motor. Engine speed depends onthe propeller size and boat load. If enginespeed is too high or too low for good engineperformance, this will have an adverse effecton the engine.Yamaha outboard motors are fitted with pro-pellers chosen to perform well over a range ofapplications, but there may be uses where apropeller with a different pitch would be moreappropriate. For a greater operating load, asmaller-pitch propeller is more suitable as itenables the correct engine speed to be main-tained. Conversely, a larger-pitch propeller ismore suitable for a smaller operating load.Yamaha dealers stock a range of propellers,and can advise you and install a propeller onyour outboard that is best suited to your appli-cation.

NOTE:Select a propeller which will allow the engineto reach the middle or upper half of the oper-ating range at full throttle with the maximumboat load. If operating conditions such as lightboat loads then allow the engine r/min to riseabove the maximum recommended range, re-duce the throttle setting to maintain the en-gine in the proper operating range.

Engine stop lanyard switchThe lock plate must be attached to the enginestop switch for the engine to run. The lanyardshould be attached to a secure place on theoperator’s clothing, or arm or leg. Should theoperator fall overboard or leave the helm, thelanyard will pull out the lock plate, stopping ig-nition to the engine. This will prevent the boatfrom running away under power.

WARNINGEWM00120

� Attach the engine stop switch lanyard toa secure place on your clothing, or yourarm or leg while operating.

� Do not attach the lanyard to clothingthat could tear loose. Do not route thelanyard where it could become entan-gled, preventing it from functioning.

� Avoid accidentally pulling the lanyardduring normal operation. Loss of enginepower means the loss of most steeringcontrol. Also, without engine power, theboat could slow rapidly. This couldcause people and objects in the boat tobe thrown forward.

NOTE:The engine cannot be started with the lockplate removed.

Mounting the outboard motor

WARNINGEWM00820

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

� The information presented in this sec-tion is intended as reference only. It isnot possible to provide complete in-structions for every possible boat andmotor combination. Proper mountingdepends in part on experience and thespecific boat and motor combination.

WARNINGEWM00830

Improper mounting of the outboard motorcould result in hazardous conditions suchas poor handling, loss of control, or firehazards. Observe the following:� For permanently mounted models, your

dealer or other person experienced inproper rigging should mount the motor.If you are mounting the motor yourself,you should be trained by an experiencedperson.

� For portable models, your dealer or oth-er person experienced in proper out-board motor mounting should show youhow to mount your motor.

Mount the outboard motor on the center line(keel line) of the boat, and ensure that theboat itself is well balanced. Otherwise theboat will be hard to steer. For boats without akeel or which are asymmetrical, consult yourdealer.

Mounting height (boat bottom)To run your boat at optimum efficiency, thewater resistance (drag) of the boat and out-board motor must be made as little as possi-ble. The mounting height of the outboardmotor greatly affects the water resistance. Ifthe mounting height is too high, cavitationtends to occur, thus reducing the propulsion;and if the propeller tips cut the air, the enginespeed will rise abnormally and cause the en-gine to overheat. If the mounting height is toolow, the water resistance will increase andthereby reduce engine efficiency. Mount theoutboard motor so that the anti-cavitationplate is in alignment with the bottom of theboat.

NOTE:� The optimum mounting height of the out-

board motor is affected by the boat/motorcombination and the desired use. Test runsat different heights can help determine theoptimum mounting height. Consult yourYamaha dealer or boat manufacturer forfurther information on determining the prop-er mounting height.

Ring Free Fuel AdditiveGasoline is a precise blend of many differentsubstances, each chosen to give certain char-acteristics. Gasoline blends have beenchanging in recent years in response to con-cerns about pollution and resulting emissionsregulations. One of the most obvious changeshas been the elimination of lead from most fu-els.As gasoline has changed, the amount of addi-tives such as aromatics and oxygenates hasincreased. These additives are important forthe engines in passenger cars, but they canhave detrimental effects in marine engines,because of increased deposits in the combus-tion chamber. When enough deposits collect,piston rings begin sticking. Performancedrops and engine wear increases dramatical-ly.While many additives available may reducedeposits, Yamaha recommends the use ofRing Free Fuel Additive, available from yourYamaha dealer. Ring Free Fuel Additivehas repeatedly proven its ability to clean com-bustion deposits from inside the engine, nota-bly the critical piston-ring-land area, and fuelsystem components.

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 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 more airdrag. Excessive trim-out can also cause thepropeller to ventilate, which reduces perfor-mance further, and the boat may “porpoise”(hop in the water), which could throw the op-erator 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. Operat-ing 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 thetrim of the boat when operating.

be careful not to damage the insulator. Adamaged insulator could allow externalsparks, which could lead to explosion orfire.


Maintenance

51

The spark plug is an important engine compo-nent and is easy to inspect. The condition ofthe spark plug can indicate something aboutthe condition of the engine. For example, if thecenter electrode porcelain is very white, thiscould indicate an intake air leak or carburetionproblem in that cylinder. Do not attempt to di-agnose any problems yourself. Instead, takethe outboard motor to a Yamaha dealer. Youshould periodically remove and inspect thespark plug because heat and deposits willcause the spark plug to slowly break downand erode. If electrode erosion becomes ex-cessive, or if carbon and other deposits areexcessive, you should replace the spark plugwith another of the correct 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 gasketsurface and use a new gasket. Wipe off anydirt from the threads and screw in the sparkplug to the correct torque.

NOTE:If a torque-wrench is not available when youare fitting a spark plug, a good estimate of thecorrect torque is 1/4 to 1/2 a turn past finger-tight. Have the spark plug adjusted to the cor-rect torque as soon as possible with a torque-wrench.
