11 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. F4D EMU25802 Fuel tank If your model was equipped with a portable fuel tank, its function is as follows.
Basic components 12 its dedicated fuel reservoir and must not be used as a fuel storage container. Com- mercial users should conform to relevant licensing or approval authority regula- tions. EMU25821 Fuel tank If your model included a fuel tank, its parts and functions are as follows.
Basic components 13 EMU25901 Open The fuel cock has two open positions, one for selecting fuel flow from the built-in fuel tank, and one for an external tank. Fuel flows to the carburetor with the lever or knob in either open position. These are the normal running positions.
Basic components 14 EMU25941 Throttle grip The throttle grip is on the tiller handle. Turn the grip counterclockwise to increase speed and clockwise to decrease speed. EMU25961 Throttle indicator The fuel consumption curve on the throttle indicator shows the relative amount of fuel consumed for each throttle position.
Basic components 15 EMU25990 Engine stop lanyard switch The lock plate must be attached to the en- gine 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.
Basic components 16 EMU26070 Manual starter handle To start the engine, first gently pull the han- dle out until resistance is felt. From that posi- tion, then pull the handle straight out quickly to crank the engine.
Basic components 17 EMU26382 Top cowling lock lever (pull up type) To remove the engine top cowling, pull up the lock lever(s) and lift off the cowling. When installing the cowling, check to be sure it fits properly in the rubber seal. Then lock the cowling by moving the lever(s) down- ward.
18 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 19 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 20 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 21 er operation before starting the engine. ● The controls should work smoothly, with- out binding or unusual free play. ● Look for loose or damaged connections. ● Check operation of the starter and stop switches when the outboard motor is in the water.
Operation 22 3. Securely close the cap after filling the tank. Wipe up any spilled fuel. NO TE: The upper fuel level mark is indicated on the built-in fuel tank.
Operation 23 3. If you are using an external fuel tank, connect the fuel joints securely and squeeze the primer pump with the outlet end up until you feel it become firm (if equipped the fuel joint). EMU27490 Starting engine EMU27505 Manual start models (tiller control) 1.
Operation 24 lanyard where it could become entan- gled, preventing it from functioning. ● Avoid accidentally pulling the lanyard during normal operation. Loss of en- gine power means the loss of most steering control. Also, without engine power, the boat could slow rapidly.
Operation 25 NO TE: ● When the engine is cold, it needs to be warmed up. For further information, see page 25. ● 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 26 EMU27763 Forward (tiller handle and remote control models) Tiller control models 1. Place the throttle grip in the fully closed position. 2.
Operation 27 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 28 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 29 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 30 W ARNING EWM00220 Be sure all people are clear of the out- board motor when tilting up and down, also be careful not to pinch any body parts between the drive unit and engine bracket.
Operation 31 4. Close the fuel cock. 5. Tilt support bar equipped models: Hold the rear of the top cowling or the rear handle (if equipped) with one hand and tilt the outboard motor up fully until the tilt support bar automatically locks.
Operation 32 3. If the tilt support knob equipped: pull out it, then slowly tilt the engine down. 4. Loosen the steering friction adjuster by turning it counterclockwise, and adjust the steering friction according to opera- tor preference.
Operation 33 EMU28101 Procedure 1. Place the gear shift lever in neutral and face the outboard motor forward. 2. Slightly tilt the outboard motor up until the tilt support bar automatically turns to the lock position to support the engine. 3. To lower the outboard motor to the nor- mal running position, first slightly tilt the outboard motor up.
