10 Basic components EMU25795 Main components NO TE: * May not be exactly as shown; also may not be included as standard equipment on all mod- els. 8D EMU25802 Fuel tank If your model was equipped with a portable fuel tank, its function is as follows.
Basic components 11 tions. EMU25830 Fuel joint This joint is used to connect the fuel line. EMU25841 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.
Basic components 12 EMU25961 Throttle indicator The fuel consumption curve on the throttle indicator shows the relative amount of fuel consumed for each throttle position. Choose the setting that offers the best performance and fuel economy for the desired operation.
Basic components 13 could cause people and objects in the boat to be thrown forward. NO TE: The engine cannot be started with the lock plate removed. EMU26001 Engine stop button To open the ignition circuit and stop the en- gine, push this button.
Basic components 14 To increase resistance, turn the adjuster clockwise. To decrease resistance, turn the adjuster counterclockwise. W ARNING EWM00040 Do not overtighten the friction adjuster. If there is too much resistance, it could be difficult to steer, which could result in an accident.
Basic components 15 1. T op co wling lock lev er(s) ZMU02862 1.
16 Operation EMU26901 Installation CAUTION: ECM00110 Incorrect engine height or obstructions to smooth water flow (such as the design or condition of the boat, or accessories such as transom ladders or depth finder transducers) can create airborne water spray while the boat is cruising.
Operation 17 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.
Operation 18 board (if packed). For details, consult your Yamaha dealer. W ARNING EWM00650 Avoid using bolts, nuts or washers other than those contained in the engine pack- aging. If used, they must be of at least the same quality of material and strength and must be tightened securely.
Operation 19 cool. 4. Third through tenth hours: Avoid operating at full throttle for more than 5 minutes at a time. Let the engine cool between full-throttle runs. Vary en- gine speed occasionally. 5. After the first 10 hours: Operate the engine normally.
Operation 20 EMU27402 Gasoline and oil mixing (100:1) If equipped with a portable fuel tank 1. Pour oil into the portable fuel tank, and then add gasoline. 2. Replace the fuel tank cap and close tightly. 3. Shake the fuel tank to mix the fuel thor- oughly.
Operation 21 2. If there is a fuel joint on the motor, firmly connect the fuel line to the joint. Then firmly connect the other end of the fuel line to the joint on the fuel tank. 3. If a steering friction adjuster is provided on your outboard motor, securely attach the fuel line to the fuel line clamp.
Operation 22 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 entan- gled, preventing it from functioning. ● Avoid accidentally pulling the lanyard during normal operation.
Operation 23 NO TE: ● When the engine is cold, it needs to be warmed up. For further information, see page 23. ● 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.
Operation 24 2. Move the gear shift lever quickly and firmly from neutral to forward. Remote control models 1. Pull up the neutral interlock trigger (if equipped) and move the remote control lever quickly and firmly from neutral to forward. EMU27795 Reverse (manual tilt and hydro tilt models) W ARNING EWM00190 When operating in reverse, go slowly.
Operation 25 until the engine comes to a complete stop. 2. After stopping the engine, tighten the air vent screw on the fuel tank cap and set the fuel cock lever or knob to the closed position, if equipped. 3. Disconnect the fuel line if you are using an external fuel tank.
Operation 26 EMU27871 Adjusting trim angle for manual tilt models There are 4 or 5 holes provided in the clamp bracket to adjust the outboard motor trim an- gle. 1. Stop the engine. 2. Remove the trim rod from the clamp bracket while slightly tilting the outboard motor up.
Operation 27 the boat is up about 3 to 5 degrees. With the bow 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 can also be adjusted to help offset this effect. When the bow of the boat is down, it is easier to accelerate from a standing start onto plane.
Operation 28 will be tilted for more than a few minutes. Otherwise fuel may leak. CAUTION: ECM00230 ● Before tilting the outboard motor, fol- low the procedure under “ Stopping en- gine ” in this chapter. Never tilt the outboard motor while the engine is run- ning.
Operation 29 EMU28013 Procedure for tilting down (manual tilt models) 1. Slightly tilt the engine up. 2. On models equipped with a tilt support knob, pull it out. 3. Slowly tilt the engine down. EMU28060 Cruising in shallow water The outboard motor can be tilted up partially to allow operation in shallow water.
Operation 30 3. The shallow water lever will lock, sup- porting the outboard motor in a partially raised position. 4. When lowering the outboard motor, slightly tilt it up and push the shallow wa- ter lever down. Slowly lower the out- board motor to the normal position.
