Safety information
●Before mounting or operating the outboard motor, read this entire manual. Reading it should give you an understanding of the motor and its operation.
●Before operating the boat, read any owner’s or operator’s manuals supplied with it and all labels. Be sure you understand each item before operating.
●Do not overpower the boat with this outboard motor. Overpowering the boat could result in loss of control. The rated power of the outboard should be equal to or less than the rated horsepower capacity of the boat. If the rated horsepower capacity of the boat is unknown, consult the dealer or boat manufacturer.
●Do not modify the outboard. Modifications could make the motor unfit or unsafe to use.
●Incorrect propeller selection and incorrect use may not only cause engine damage, but also adversely affect fuel consumption. Consult your dealer for correct use.
●Never operate after drinking alcohol or taking drugs. About 50% of all boating fatalities involve intoxication.
●Have an approved personal flotation device (PFD) on board for every occupant. It
is a good idea to wear a PFD whenever boating. At a minimum, children and nonswimmers should always wear PFDs, and everyone should wear PFDs when there are potentially hazardous boating conditions.
●Gasoline is highly flammable, and its vapors are flammable and explosive. Handle and store gasoline carefully. Make sure there are no gas fumes or leaking fuel before starting the engine.
●This product emits exhaust gases which contain carbon monoxide, a colorless, odorless gas which may cause brain damage or death when inhaled. Symptoms include nausea, dizziness, and drowsiness. Keep cockpit and cabin areas well ventilated. Avoid blocking exhaust outlets.
●Check throttle, shift, and steering for proper operation before starting the engine.
●Attach the engine stop switch lanyard to a secure place on your clothing, or your arm or leg while operating. If you accidentally leave the helm, the lanyard will pull from the switch, stopping the engine.
●Know the marine laws and regulations where you will be boating - and obey them.
●Stay informed about the weather. Check weather forecasts before boating. Avoid boating in hazardous weather.
●Tell someone where you are going: leave a Float Plan with a responsible person. Be sure to cancel the Float Plan when you return.
●Use common sense and good judgment when boating. Know your abilities, and be sure you understand how your boat handles under the different boating conditions you may encounter. Operate within your limits, and the limits of your boat. Always operate at safe speeds, and keep a careful
3
General information
watch for obstacles and other traffic.
●Always watch carefully for swimmers during the 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 correct processing of empty containers, consult the dealer where you purchased the oil.
●When replacing oils used to lubricate the product (engine or gear oil), be sure to wipe away any spilt oil. Never pour oil without using a funnel or similar device. If necessary, verify the necessary replacement procedure with the dealer.
●Never illegally discard (dump) the product. Yamaha recommends consulting the deal-
er on discarding the product.

WARNING
GASOLINE AND ITS VAPORS ARE HIGHLY FLAMMABLE AND EXPLOSIVE!
●Do not smoke when refueling, and keep away from sparks, flames, or other sources of ignition.
●Stop engine before refueling.
●Refuel in a well-ventilated area. Refuel portable fuel tanks off the boat.
●Take care not to spill gasoline. If gasoline spills, wipe it up immediately with dry rags.
●Do not overfill the fuel tank.
●Tighten the filler cap securely after refueling.
●If you should swallow some gasoline, inhale a lot of gasoline vapor, or get gasoline in your eyes, get immediate medical attention.
●If any gasoline spills onto your skin, immediately wash with soap and water. Change clothing if gasoline spills on it.
●Touch the fuel nozzle to the filler opening or funnel to help prevent electrostatic sparks.

CAUTION:
Use only new clean gasoline which has been stored in clean containers and is not contaminated with water or foreign matter.

Recommended engine oil:
4-stroke motor oil with a combination of the following SAE and API oil classifications
Engine oil type SAE: 10W-30 or 10W-40 Engine oil grade API:
SE, SF, SG, SH, SJ, SL
Engine oil quantity (excluding oil filter): 4.3 L (4.55 US qt) (3.78 Imp.qt)
NOTE:
If the recommended engine oil grades are not available, select an alternative from the following chart according to the average temperatures in your area.

CAUTION:
Do not use a battery that does not meet the specified capacity. If a battery which does not meet specifications is used, the electric system could perform poorly or be overloaded, causing electric system damage.
For electric start models, choose a battery

Minimum cold cranking amps (CCA/EN): 430.0 A
Minimum rated capacity (20HR/IEC): 70.0 Ah
EMU25742
Propeller selection
The performance of your outboard motor will be critically affected by your choice of propeller, as an incorrect choice could adversely affect performance and could also seriously damage the motor. Engine speed depends on the propeller size and boat load. If engine speed is too high or too low for good engine performance, this will have an adverse effect on the engine.
Yamaha outboard motors are fitted with propellers chosen to perform well over a range of applications, but there may be uses where a propeller with a different pitch would be more appropriate. For a greater operating load, a smaller-pitch propeller is more suitable as it enables the correct engine speed to be maintained. Conversely, a larger-pitch propeller is more suitable for a smaller operating load.
Yamaha dealers stock a range of propellers, and can advise you and install a propeller on your outboard that is best suited to your application.

NOTE:
Select a propeller which will allow the engine to reach the middle or upper half of the operating range at full throttle with the maximum boat load. If operating conditions such as light boat loads then allow the engine r/min to rise above the maximum recommended range, reduce the throttle setting to maintain the engine in the proper operating range.
For instructions on propeller removal and installation, see page 56.
EMU25760
Start-in-gear protection
Yamaha outboard motors affixed with the pictured label or Yamaha-approved remote control units are equipped with start-in-gear protection device(s). This feature permits the engine to be started only when it is in neutral. Always select neutral before starting the engine.

A friction device provides adjustable resistance to movement of the throttle grip or the remote control lever, and can be set according to operator preference.
To increase resistance, turn the adjuster clockwise. To decrease resistance, turn the adjuster counterclockwise.

WARNING
Do not overtighten the friction adjuster. If there is too much resistance, it could be difficult to move throttle lever or grip, which could result in an accident.

Engine stop lanyard switch
The lock plate must be attached to the engine stop switch for the engine to run. The lanyard should be attached to a secure place on the operator’s clothing, or arm or leg. Should the operator fall overboard or leave the helm, the lanyard will pull out the lock plate, stopping ignition to the engine. This will prevent the boat from running away under power.
EWM00120
WARNING
●Attach the engine stop switch lanyard to a secure place on your clothing, or your arm or leg while operating.
●Do not attach the lanyard to clothing that could tear loose. Do not route the lanyard where it could become entangled, preventing it from functioning.
●Avoid accidentally pulling the lanyard 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 objects in the boat to be thrown forward.
NOTE:
The engine cannot be started with the lock plate removed.
