running away under power and leaving peo- ple stranded, or running over people or ob- jects... Always attach the engine shut-off cord to a secure place on your clothing or your arm or leg while operating... Do not remove it to leave the helm while the boat is moving... Do not at- tach the cord to clothing that could tear loose, or route the cord where it could become en- tangled, preventing it from functioning... Do not route the cord where it is likely to be accidentally pulled out... If the cord is pulled during operation, the engine will shut off and you will lose most steering control... The boat could slow rapidly, throwing people and ob- jects forward... EMU33810

Page 7

People in the water Always 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 into neutral and stop the engine... Stay away from swimming areas... Swimmers can be hard to see... The propeller can keep moving even when the motor is in neutral... Stop the engine when a person is in the water near you... EMU33751

You may also want to consider an Internet- based program for basic boater education... The Online Boating Safety Course provided by the BoatU... S... Foundation, is approved by the National Association of State Boating Law Administrators (NASBLA) and recognized by the United States Coast Guard... Most, but not all, states accept this course to meet their minimum requirements... While it cannot re- place an in-depth course such as one offered by the U... S... Coast Guard, U... S... Power Squad- ron, or other organization, this online course does provide a general overview of the basics in boating safety, requirements, navigation, and operation... Upon successful completion of the course, the user can download a certifi- cate of completion immediately or, for a small charge, request one by mail... To take this free course, go to boatus... org... EMU33880

Just as there are rules that apply when you are driving on streets and highways, there are waterway rules that apply when you are driv- ing your boat... These rules are used interna- tionally... (For U... S... A... : and are also enforced by the United States Coast Guard and local agencies... ) You should be aware of these rules, and follow them whenever you encoun- ter another vessel on the water... EMU33700

Page 10

slow down or change directions briefly and pass behind the other vessel... You should al- ways move in such a way that the operator of the other vessel can see what you are doing... The general prudential rule This rule is called Rule 2 in the International Rules and says, In obeying and construing these rules due regard shall be had to all dangers of naviga- tion and collision, and to any special circum- stances, which may render a departure from the above rules necessary in order to avoid immediate danger... In other words, follow the standard rules ex- cept when a collision will occur unless both vessels try to avoid each other... If that is the case, both vessels become Give-Way ves- sels... EMU25521

Page 11

Other special situations There are three other rules you should be aware of when driving your boat around other vessels... Narrow channels and bends When navigating in narrow channels, you should keep to the right when it is safe and practical to do so... If the operator of a power- driven vessel is preparing to go around a bend that may obstruct the view of other water vessels, the operator should sound a pro- longed blast on the whistle (4 to 6 seconds)... If another vessel is around the bend, it too should sound the whistle... Even if no reply is heard, however, the vessel should still pro- ceed around the bend with caution... If you nav- igate such waters with your boat, you will need to carry a portable air horn, available from local marine supply stores...

Page 12

Many bodies of water used by boaters are en- tirely within the boundaries of a particular state... The Uniform State Waterway Marking System has been devised for these waters... This system uses buoys and signs with dis- tinctive shapes and colors to show regulatory or advisory information... These markers are

Page 13

Outboard motor serial number The outboard motor serial number is stamped on the label attached to the port side of the clamp bracket... Record your outboard motor serial number in the spaces provided to assist you in ordering spare parts from your Yamaha dealer or for reference in case your outboard motor is sto- len...

Page 14

Read manuals and labels Before operating or working on this motor: Read this manual... Read any manuals supplied with the boat... Read all labels on the outboard motor and the boat... If you need any additional information, contact your Yamaha dealer... EMU33831

Specifications TIP: (AL) stated in the specification data below represents the numerical value for the alumi- num propeller installed...

Page 18

Propeller selection Next to selecting an outboard motor, selecting the right propeller is one of the most important purchasing decisions a boater can make... The type, size, and design of your propeller have a direct impact on acceleration, top speed, fuel economy, and even engine life... Yamaha designs and manufactures propellers for ev- ery Yamaha outboard motor and every appli- cation... Your outboard motor came with a Yamaha propeller selected to perform well over a range of applications, but there may be uses where a different propeller would be more ap- propriate... Your Yamaha dealer can help you select the right propeller for your boating needs... Select a propeller that will allow the engine to reach the middle or upper half of the operating range at full throttle with the maximum boat- load... Generally, select a larger pitch propeller for a smaller operating load and a smaller pitch propeller for a heavier load... If you carry loads that vary widely, select the propeller that lets the engine run in the proper range for your maximum load but remember that you may need to reduce your throttle setting to stay within the recommended engine speed range when carrying lighter loads... To check the propeller, see page 61...

Page 19

Gasoline Use a good quality gasoline that meets the minimum octane rating... If knocking or pinging occurs, use a different brand of gasoline or premium unleaded fuel... Yamaha recomends that you use alcohol-free (see Gasohol) gas- oline whenever possible...

Page 20

Gasohol There are two types of gasohol: gasohol con- taining ethanol (E10) and that containing methanol... Ethanol can be used if the ethanol content does not exceed 10% and the fuel meets the minimum octane ratings... E85 is a fuel containing 85% ethanol and must not be used in your outboard motor... All ethanol blends containing more than 10% ethanol can cause fuel system damage or cause engine starting and running problems... Yamaha does not recommend gasohol containing methanol because it can cause fuel system damage or engine performance problems... It is recommended that you install a water- separating marine fuel filter assembly (10 mi- cron minimum) between your boats fuel tank and outboard motor when using ethanol... Eth- anol is known to allow moisture to be ab- sorbed into boat fuel tanks and systems... Moisture in the fuel can cause corrosion of metallic fuel system components, starting and running complaints and require additional fuel system maintenance... EMU27270

Four StarsSuper Ultra Low Emission The four-star label identifies engines that meet the Air Resources Boards Sterndrive and Inboard marine engine 2009 exhaust emission standards... Personal Watercraft and Outboard marine engines may also comply with these standards... Engines meeting these standards have 90% lower emissions than One Star-Low-Emission engines...

Fuel tank (portable fuel tank) This model can be equipped with an optional portable fuel tank... The parts of the fuel tank are as follows... Fuel tank cap This cap seals the fuel tank... When removed, the tank can be filled with fuel... To remove the cap, turn it counterclockwise... Air vent screw This screw is on the fuel tank cap... To loosen the screw, turn it counterclockwise... Fuel joint This joint is used to connect the fuel line... Fuel gauge This gauge is located on either the fuel tank cap or on the fuel joint base... It shows the ap- proximate amount of fuel remaining in the tank...

Page 25

Open To send fuel from the fuel tank to the carbure- tor, align the fuel cock with the position for the built-in fuel tank or portable fuel tank accord- ing to which fuel tank is being used... When using the built-in fuel tank, align the fuel cock with the built-in fuel tank position... When using a portable fuel tank, align the fuel cock with the portable fuel tank position...

Page 26

Throttle friction adjuster The throttle friction adjuster provides adjust- able resistance when the throttle grip is turned, and can be set according to operator preference... To increase resistance, turn the throttle fric- tion adjuster clockwise... To decrease resistance, turn the throttle fric- tion adjuster counterclockwise... When con- stant speed is desired, tighten the throttle friction adjuster to maintain the desired throt- tle setting... WARNING! Do not overtighten the throttle friction adjuster... If there is too much resistance, it could be difficult to turn the throttle grip, which could result in an accident... [EWM02261]

Page 27

Engine shut-off cord (lanyard) and clip The clip must be attached to the engine shut- off switch for the engine to run... The cord should be attached to a secure place on the operators clothing, or arm or leg... Should the operator fall overboard or leave the helm, the cord will pull out the clip, stopping ignition to the engine... This will prevent the boat from running away under power... WARNING! At- tach the engine shut-off cord to a secure place on your clothing, or your arm or leg while operating... Do not attach the cord to clothing that could tear loose... Do not route the cord where it could become entangled, preventing it from functioning... Avoid acci- dentally pulling the cord during normal operation... Loss of engine power means the loss of most steering control... Also, without engine power, the boat could slow rapidly... This could cause people and ob- jects in the boat to be thrown forward... [EWM00122]

Page 28

Tilt lock mechanism The tilt lock mechanism is used to prevent the outboard motor from lifting out of the water when the gear shift lever is in the reverse po- sition... When the gear shift lever is moved to the re- verse position, the tilt lock mechanism oper- ates to prevent the outboard motor from being tilted up...

Page 29

Carrying handle The carrying handle is used to carry the out- board motor... For information on carrying and transporting the outboard motor, see page 47...

Installation The information presented in this section is in- tended as reference only... It is not possible to provide complete instructions for every possi- ble boat and motor combination... Proper mounting depends in part on experience and the specific boat and motor combination...

Page 32

Mounting height To run your boat at optimum efficiency, the water resistance (drag) of the boat and out- board motor must be made as little as possi- ble... The mounting height of the outboard motor greatly affects the water resistance... If the mounting height is too high, cavitation tends to occur, thus reducing the propulsion; and if the propeller tips cut the air, the engine speed will rise abnormally and cause the en- gine to overheat... If the mounting height is too low, the water resistance will increase and thereby reduce engine efficiency... Mount the outboard motor so that the anti-cavitation plate is between the bottom of the boat and a level 25 mm (1 in) below it...

Page 33

Incorrect engine height or obstructions to the smooth flow of water (such as the design or condition of the boat) can cre- ate airborne water spray while the boat is cruising... If the motor is operated con- tinuously in the presence of airborne water spray, enough water could enter the engine through the intake opening on the top cowling to cause severe en- gine damage... Eliminate the cause of the airborne water spray...

Page 34

Breaking in engine Your new engine requires a period of break-in to allow mating surfaces of moving parts to wear in evenly... Correct break-in will help en- sure proper performance and longer engine life... NOTICE: Failure to follow the break-in procedure could result in reduced engine life or even severe engine damage... [ECM00801]

Page 35

Removing top cowling For the following checks, remove the top cowling from the bottom cowling... To remove the top cowling, pull the cowling lock lever up and lift up the top cowling...

Page 36

TIP: The oil lubrication check window does not in- dicate the engine oil level... Use the oil lubrica- tion check window to make sure that the engine is being lubricated with oil while it is running... 3... Install the oil filler cap and tighten it com-

Page 37

6... Check the fitting of the top cowling by pushing it with both hands... NOTICE: If the top cowling is not installed cor- rectly, water spray under the top cowl- ing can damage the engine, or the top cowling can blow off at high speeds... [ECM01991]

Page 38

Gasoline is poisonous and can cause in- jury or death... Handle gasoline with care... Never siphon gasoline by mouth... If you should swallow some gasoline or inhale a lot of gasoline vapor, or get some gas- oline in your eyes, see your doctor im- mediately... If gasoline spills on your skin, wash with soap and water... If gaso- line spills on your clothing, change your clothes...

Page 39

This product emits exhaust gases which contain carbon monoxide, a colorless, odorless gas which could cause brain damage or death when inhaled... Symp- toms include nausea, dizziness, and drowsiness... Keep cockpit and cabin ar- eas well ventilated... Avoid blocking ex- haust outlets...

Page 40

3... Remove the fuel joint cap... Connect the fuel hose securely between the tank and the outboard motor so that the primer pump arrow is pointing toward the out- board motor...

Page 41

Failure to attached engine shut-off cord could result in a runaway boat if opera- tor is ejected... Attach the engine shut-off cord to a secure place on your clothing, or your arm or leg while operating... Do not attach the cord to clothing that could tear loose... Do not route the cord where it could become entangled, preventing it from functioning...

Page 42

2... Attach the engine shut-off cord to a se- cure place on your clothing, or your arm or leg... Then, install the clip on the other end of the cord to the engine shut-off switch...

Page 43

If water is not flowing out of the pilot hole at all times while the engine is running, overheating and serious damage could occur... Stop the engine and check whether the cooling water inlet on the lower case or the cooling water pilot hole is blocked... Consult your Yamaha dealer if the prob- lem cannot be located and corrected...

Page 44

Before shifting the outboard motor, turn the throttle grip to the fully closed position and let the engine speed return to idle speed... Otherwise, the shift mechanism could be damaged...

Page 45

Do not use the reverse function to slow down or stop the boat as it could cause you to lose control, be ejected, or impact the load or other parts of the boat... This could increase the risk of serious injury... It could also damage the shift mechanism...

Page 46

Excessive trim for the operating condi- tions (either trim up or trim down) can cause boat instability and can make steer- ing the boat more difficult... This increases the possibility of an accident... If the boat begins to feel unstable or is hard to steer, slow down and/or readjust the trim angle...

Page 47

Bow Up Too much trim-out puts the bow of the boat too high in the water... Excessive trim-out can also cause the propeller to ventilate, which re- duces performance further, and the boat may porpoise (hop in the water), which could throw the operator and passengers over- board...

Page 48

Tilting up and down If the engine will be stopped for some time or if the boat is moored in shallows, the outboard motor should be tilted up to protect the propel- ler and lower case from damage due to colli- sions with obstructions, and also to reduce salt corrosion...

Page 49

6... Hold the rear of the top cowling and fully tilt the outboard motor up... Slightly lower the outboard motor from the fully tilted up position and fit the tilt support bar secure- ly into the holder located on the clamp bracket...

Page 50

3... Turn the steering friction adjuster coun- terclockwise to set the steering friction according to operator preference... WARNING! If there is too much resis- tance it could be difficult to steer, which could result in an accident... [EWM00721]

Page 51

Cruising in other conditions Cruising in salt water After operating in salt water, flush the cooling water passages with fresh water to prevent them from becoming clogged... Also rinse the outside of the outboard motor with fresh wa- ter... Cruising in muddy, turbid, or acidic water Water in some areas can be acidic or with a lot of sediment in it, such as muddy or turbid (cloudy) water... After operating in such water, flush the cooling passages with fresh water to prevent corrosion... Also rinse the outside of the outboard motor with fresh water...

Page 52

4... When using a portable fuel tank, discon- nect the fuel hose from the fuel joint, and then install the fuel joint cap... WARNING! When not using a portable fuel tank, make sure to install the fuel joint cap... Otherwise, injury could result from striking the fuel joint accidentally... [EWM02411]

Page 53

8... Hold the carrying handle and the hand- grip on the front side of the bottom cowl- ing and lift up the outboard motor using two people to dismount it from the boat...

Page 54

10... If transporting or storing the outboard mo- tor horizontally cannot be avoided, tight- en the clamp screws completely, place a towel or something similar under the out- board motor to protect it from damage, and then place the outboard motor in the attitude shown... If the front side of the out- board motor is facing down, turn the clamp bracket 90 so that it does not con- tact the ground, and then turn the steer- ing friction adjuster clockwise to secure the bracket...

Page 55

Cooling system flushing is essential to pre- vent the cooling system from clogging up with salt, sand, or dirt... In addition, fogging of the engine is mandatory to prevent excessive en- gine damage due to rust... Perform the flushing and fogging at the same time... 1... Wash the outboard motor body using

Page 57

Checking painted surface of motor Check the motor for scratches, nicks, or flak- ing paint... Areas with damaged paint are more likely to corrode... If necessary, clean and paint the areas... A touch-up paint is available from your Yamaha dealer...

Page 58

Maintenance interval guidelines The service intervals provided in the Mainte- nance Chart were developed based upon typical use that includes operating at varied speeds, with sufficient time for engine warm up and cool-down, a medium to light load, and an average cruising speed near the 3000 to 4000 rpm range... As with any engine, howev- er, if your normal operating conditions are dif- ferent, you should consider service more often than shown, especially how often you change your engine and gear oil... Examples might include extended wide-open-throttle use or long periods of trolling or idling, carry- ing heavy loads, or frequent starting and stop- ping or shifting... More frequent maintenance will often pay off many times over in increased engine life and greater owner satisfaction... Consult your Yamaha dealer for additional maintenance recommendations...

Cleaning and adjusting spark plug The spark plug is an important engine compo- nent... The condition of the spark plug can indi- cate something about the condition of the engine... For example, if the center electrode porcelain is very white, this could indicate an intake air leak or carburetion problem in that cylinder... Do not attempt to diagnose any problems yourself... Instead, take the outboard motor to a Yamaha dealer... You should peri- odically remove and inspect the spark plug because heat and deposits will cause the spark plug to slowly break down and erode... 1... Remove the spark plug cap from the

Page 65

15... Start the engine and make sure that there are no oil leaks... NOTICE: If there are oil leaks, stop the engine and find the cause... Consult your Yamaha dealer if the problem cannot be located and corrected... Continued operation with a problem could cause severe engine damage... [ECM02150]

Page 66

You could be seriously injured if the en- gine accidentally starts when you are near the propeller... Before inspecting, remov- ing, or installing the propeller, place the gear shift lever in neutral, and remove the clip from the engine shut-off switch...

Page 67

2... Install the thrust washer and propeller onto the propeller shaft... NOTICE: Be sure to install the thrust washer before installing the propeller, otherwise the lower case and propeller boss could be damaged... [ECM01880]

Page 68

4... Remove the oil level plug and gasket to allow the oil to drain completely... NOTICE: Check the used oil after it has been drained... If the oil is milky or contains a large amount of metal par- ticles, the gear case may be damaged... Have a Yamaha dealer check and re- pair the outboard motor... [ECM00712]

Page 69

Troubleshooting This section describes the likely causes and remedies for problems, such as those in the fuel, compression, and ignition systems, poor starting, and loss of power... Please note that all of the items in this section may not apply to your model... If your outboard motor requires repair, bring it to a Yamaha dealer...

Page 70

Q... Is spark plug wiring damaged or poorly connected? A... Check wires for wear or breaks... Tighten all loose connections... Replace worn or broken wires...

Page 71

When the emergency starter rope is used to start the engine, the start-in- gear protection device does not operate... Make sure that the shift lever is in the neutral position... Otherwise, the boat could unexpectedly start to move, which could result in an accident...

Page 72

An unguarded, rotating flywheel is very dangerous... Keep loose clothing and other objects away when starting the en- gine... Use the emergency starter rope only as instructed... Do not touch the fly- wheel or other moving parts when the engine is running... Do not install the starter mechanism or top cowling after the engine is running...

Page 73

7... Attach the engine shut-off cord to a se- cure place on your clothing, or your arm or leg... Then, install the clip on the other end of the cord to the engine shut-off switch...

Page 74

Treatment of submerged motor If the outboard motor is submerged, immedi- ately take it to a Yamaha dealer... Otherwise some corrosion may begin almost immediate- ly... NOTICE: Do not attempt to run the out- board motor until it has been completely inspected... [ECM00401]
