26 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 27 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 28 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 29 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 30 EMU27270 Ring Free Fuel Additive Gasoline is a precise blend of many different substances, each chosen to give certain characteristics. Gasoline blends have been changing in recent years in response to con- cerns about pollution and resulting emis- sions regulations.
Operation 31 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. NO TE: During engine operation place the tank hori- zontally, otherwise fuel cannot be drawn from the fuel tank.
Operation 32 3. Place the throttle grip in the “” (start) position. 4. Pull the manual starter handle slowly un- til you feel resistance. Then give a strong pull straight out to crank and start the engine. Repeat if necessary. 5. After the engine starts, slowly return the manual starter handle to its original po- sition before releasing it.
Operation 33 during normal operation. Loss of en- gine 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. 3. Place the throttle grip in the “” (start) position.
Operation 34 NO TE: The start-in-gear protection device prevents the engine from starting except when in neu- tral. 2. Attach the engine stop switch lanyard to a secure place on your clothing, or your arm or leg. Then install the lock plate on the other end of the lanyard into the en- gine stop switch.
Operation 35 again. NO TE: ● When the engine is cold, it needs to be warmed up. For further information, see page 35. ● If the engine is warm and fails to start, open the throttle slightly and try to start the engine again. If the engine still fails to start, see page 72.
Operation 36 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.
Operation 37 EMU27795 Reverse (manual tilt and hydro tilt models) W ARNING EWM00190 When operating in reverse, go slowly. Do not open the throttle more than half. Oth- erwise the boat could become unstable, which could result in loss of control and an accident.
Operation 38 EMU27820 Stopping engine Before stopping the engine, first let it cool off for a few minutes at idle or low speed. Stop- ping the engine immediately after operating at high speed is not recommended. EMU27844 Procedure 1. Push and hold the engine stop button or turn the main switch to “” (off).
Operation 39 also affected by variables such as the load in the boat, sea conditions, and running speed. W ARNING EWM00740 Excessive trim for the operating condi- tions (either trim up or trim down) can cause boat instability and can make steering the boat more difficult.
Operation 40 EMU27881 Adjusting trim angle Power trim and tilt models W ARNING EWM00750 ● Be sure all people are clear of the out- board motor when adjusting the tilt an- gle, also be careful not to pinch any body parts between the drive unit and clamp bracket.
Operation 41 Bow Up Too much trim-out puts the bow of the boat too high in the water. Performance and econ- omy are decreased because the hull of the boat is pushing the water and there is more air drag.
Operation 42 on page 38. Never tilt the outboard mo- tor while the engine is running. Severe damage from overheating can result. ● Do not tilt up the engine by pushing the tiller handle (if equipped) because this could break the handle. EMU27976 Procedure for tilting up (manual tilt models) 1.
Operation 43 EMU28005 Procedure for tilting up Power trim and tilt models / power tilt models 1. Place the remote control lever / the gear shift lever in neutral.
