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

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 11

Give-way vessel The vessel that does not have the right-of- way has the duty to take positive and timely action to stay out of the way of the Stand-On vessel... Normally, you should not cross in front of the vessel with the right-of-way... You should 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 12

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... 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 with trolling 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-way Sailing vessels should normally be given the right-of-way... The exceptions to this are: 1... When the sailing vessel is overtaking the

are passed on the starboard (right) side when proceeding from open water into port, and black buoys are to port (left) side... When navi- gating out of port, your position with respect to the buoys should be reversed; red buoys should be to port and black buoys to star- board... 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 white 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 unfamiliar waters...

Specifications TIP: (AL) stated in the specification data below represents the numerical value for the alumi- num propeller installed... EMU2821S

Page 24

Before installing the outboard motor(s), con- firm that the total horsepower of your out- board motor(s) does not exceed the boats maximum horsepower rating... See the boats capacity plate or contact the manufacturer...

Page 25

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 88... F2... 5

Page 26

Gasoline Use a good quality gasoline that meets the minimum octane requirement... If knocking or pinging occurs, use a different brand of gaso- line 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 result in starting and running problems... If you en- counter drivability problems, which you sus- pect could be related to the fuel you are using, we recommend that you switch to a recog- nized high quality brand of gasoline, such as

Page 27

Gasoline with Ethanol Two types of gasoline are commonly avail- able in the U... S... A... and Canada for use in au- tomobiles and boats: conventional gasoline without Ethanol and gasoline with Ethanol, which is typically referred to as E10 gasoline... According to federal regulations, E10 gaso- line may contain up to 10% Ethanol... A high quality gasoline without Ethanol is the preferred fuel for your Yamaha outboard mo- tor... However, if gasoline with Ethanol is the only fuel available in your area, your Yamaha outboard motor is calibrated to run properly on fresh E10 gasoline that meets the mini- mum octane requirement specified for this model...

Page 28

Gasoline Additives Gasoline blends change to meet automobile emission regulations and economic condi- tions... Additives, added by gasoline distribu- tors, necessary for proper automobile engine operation and durability, may not be sufficient for typical boat applications... Intake valve and combustion chamber deposits may accumu- late in boat engines more rapidly than en- countered in automotive use... In addition, gasoline used for boating will typically age longer between refills than gasoline used in automobiles, resulting in stale and unusable gasoline that may cause starting and running problems, fuel system damage, and internal engine damage... Yamaha recommends the use of two Ya- malube gasoline additives to reduce internal deposits and extend the storage life of gaso- line... Continuous use of Yamalube Ring Free Fuel Additive Plus reduces harmful internal deposits... Yamalube Fuel Stabilizer & Condi- tioner Plus added to fresh gasoline will help protect the fuel system from varnishing while helping to keep the gasolines octane level from decreasing excessively during storage... Other additives may also be available on the market that may have varying degrees of ef-

Star labels Your outboard motor is labeled with a Califor- nia Air Resources Board (CARB) star label... See below for a description of your particular label... F2... 5

Page 31

One StarLow Emission The one-star label identifies engines that meet the Air Resources Boards Personal Watercraft and Outboard marine engine 2001 exhaust emission standards... Engines meet- ing these standards have 75% lower emis- sions than conventional carbureted two- stroke engines... These engines are equivalent to the U... S... EPAs 2006 standards for marine engines...

Page 36

F4, F6 The fuel cock turns on and off the supply of fuel from the fuel tank to the engine... The fuel cock has 3 positions: the closed po- sition, built-in fuel tank position, and portable fuel tank position... Depending on how the out- board motor will be used, align the fuel cock with the appropriate position indicated on the label that is affixed to the outboard motor...

Page 37

F4, F6 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 38

Throttle indicator The throttle indicator shows the throttle posi- tion... When the 100% position of the throttle in- dicator is aligned with the notch in the tiller handle, the throttle is fully open... When the 0% position of the throttle indicator is aligned with the notch in the tiller handle, the throttle is fully closed...

Page 39

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]

so that it is positioned as close to the cen- ter as possible... Tighten the clamp screws evenly and securely... Occasionally check the clamp screws for tightness during op- eration of the outboard motor because they could become loose due to engine vibration... WARNING! Loose clamp screws could allow the outboard mo- tor to fall off or move on the transom... This could cause loss of control and serious injury... Make sure the clamp screws are tightened securely... Occa- sionally check the screws for tight- ness during operation... [EWM00642]

Page 48

2... Attach one end to the restraint cable at- tachment and the other to a secure mounting point on the boat... Otherwise the engine could be completely lost if it accidentally falls off the transom...

Page 49

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]

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 55

4... Wipe up any spilled gasoline immediately with dry rags... Dispose of rags properly according to local laws or regulations... If you use a portable container to store and dispense fuel, only use a locally ap- proved GASOLINE container...

Page 56

7... Fill the fuel tank with fuel... WARNING! Do not overfill... Otherwise fuel can expand and overflow if the temperature in- creases... [EWM02610]

Page 57

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 58

2... If there is fuel in the built-in fuel tank, open the air vent valve to prevent pres- sure from increasing inside the tank due to fuel expansion...

Page 59

4... Remove the fuel joint cap... Align the fuel joint on the fuel hose with the fuel joint on the outboard motor and connect the fuel hose securely between the tank and the outboard motor while pinching the joint so that the primer pump arrow is pointing to- ward the outboard motor...

Page 60

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 61

If the engine does not start on the first try, repeat the procedure... If the engine fails to start after 4 or 5 tries, open the throttle a small amount (between 1/8 and 1/4) and try again... Also if the engine is warm and fails to start, open the throttle a same amount and try to start the engine again... If the engine still fails to start, see page 92...

Page 62

TIP: It is not necessary to use the choke when starting a warm engine, such as immediately after the outboard motor has been operated under a load... 5... Pull the manual starter handle slowly until

Page 63

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 64

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 65

Stopping boat (F2... 5) The boat is not equipped with a separate braking system... Water resistance stops it af- ter the throttle lever is moved back to the fully closed position... The stopping distance varies depending on gross weight, water surface conditions, and wind direction...

Page 66

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 67

4... After stopping the engine, disconnect the fuel hose from the fuel joint on the out- board motor, and then install the fuel joint cap... WARNING! When not using a por- table fuel tank, make sure to install the fuel joint cap... Otherwise, injury could result from striking the fuel joint acci- dentally... [EWM02411]

Page 68

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 69

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

Page 70

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 71

Leaking fuel is a fire hazard... Close the air vent valve or air vent screw and place the fuel cock in the closed position if the out- board motor will be tilted for more than a few minutes... Otherwise, fuel may leak...

Page 72

TIP: If the outboard motor is not facing forward, the tilt support lever cannot automatically turn to the locked position... If the tilt support lever does not automatically lock, swing the out- board motor a little to the left and right... F4, F6 1... Align the fuel cock with the closed posi-

vent screw... The outboard motor should be transported and stored in the normal running position... If there is insufficient road clearance in this po- sition, then trailer the outboard motor in the tilted position using a motor support device such as a transom saver bar... Consult your Yamaha dealer for further details... EMU43513

Page 77

Do not hold the top cowling or tiller handle when mounting or dismounting the out- board motor... Otherwise, the outboard mo- tor could fall...

Page 78

11... 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 79

Storing outboard motor When storing your Yamaha outboard motor for prolonged periods of time (2 months or longer), several important procedures must be performed to prevent excessive damage... It is advisable to have your outboard motor serviced by an authorized Yamaha dealer pri- or to storage... However, the following proce- dures can be performed by the owner...

Page 80

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 oil and gear oil... Exam- ples might include extended wide-open-throt- tle use or long periods of trolling or idling, carrying heavy loads, or frequent starting and stopping or shifting... More frequent mainte-

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
