24 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. Severe engine damage may result if the motor is operated conti[...]

Operation 25 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. If the mounting height is too low, the water resistance will increase and thereby reduc[...]

Operation 26 throttle to 3000 r/min or less. 3. Next two hours: Accelerate at full throttle onto plane, then reduce engine speed to three-quar- ter throttle (approximately 4000 r/min). Vary engine speed occasionally. Run at full throttle for one minute, then allow about 10 minutes of operation at three- quarter throttle or less to let the engine co[...]

Operation 27 pipes. After any air in the oil lines has been expelled, the oil injection system should supply oil normally. If no oil is flowing after 10 minutes of idling, consult your Yamaha dealer. CAUTION: ECM00130 Be sure to take the above steps when op- erating the engine after a long period of storage. Otherwise engine seizure could occur. EM[...]
