Important manual information EMU31280 To the owner Thank you for choosing a Yamaha outboard motor. This Owner's Manual contains information needed for proper operation, maintenance and care. A thorough understanding of these simple instructions will help you obtain maximum enjoyment from your new Yamaha. If you have any question about the operation or maintenance of your outboard motor, please consult a Yamaha dealer. [. . . ] The information presented in this section is intended as reference only. It is not possible to provide complete instructions for every possible boat and motor combination. Proper mounting depends in part on experience and the 1 1. Center line (keel line) EMU26930 ZMU01760 Mounting height (boat bottom) To run your boat at optimum efficiency, the water resistance (drag) of the boat and outboard motor must be made as little as possible. The mounting height of the outboard 35 Operation 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 engine to overheat. If the mounting height is too low, the water resistance will increase and thereby reduce engine efficiency. Mount the outboard motor so that the anti-cavitation plate is in alignment with the bottom of the boat. life. ECM00800 CAUTION: Failure to follow the break-in procedure could result in reduced engine life or even severe engine damage. EMU27081 Procedure for 4-stroke models Run the engine under load (in gear with a propeller installed) for 10 hours as follows. First hour: Run the engine at 2000 r/min or at approximately half throttle. Second hour: Run the engine at 3000 r/min or at approximately three-quarter throttle. Remaining eight hours: Run the engine at any speed. However, avoid operating at full throttle for more than 5 minutes at a time. After the first 10 hours: Operate the engine normally. EMU27103 ZMU01762 NOTE: G G The optimum mounting height of the outboard motor is affected by the boat/motor combination and the desired use. Test runs at different heights can help determine the optimum mounting height. Consult your Yamaha dealer or boat manufacturer for further information on determining the proper mounting height. For instructions on setting the trim angle of the outboard motor, see page 45. Preoperation checks EWM00080 WARNING If any item in the preoperation check is not working properly, have it inspected and repaired before operating the outboard motor. Otherwise an accident could occur. ECM00120 EMU30173 CAUTION: Breaking in engine Your new engine requires a period of breakin to allow mating surfaces of moving parts to wear in evenly. Correct break-in will help ensure proper performance and longer engine Do not start the engine out of water. Overheating and serious engine damage can occur.

Check fuel line connections to be sure they are tight (if equipped Yamaha fuel tank or boat tank). [. . . ] Use the emergency starter rope 79 Trouble Recovery only as instructed. Do not touch the flywheel or other moving parts when the engine is running. Do not install the starter mechanism or top cowling after the engine is running. Do not touch the ignition coil, spark plug wire, spark plug cap, or other electrical components when starting or operating the motor. [. . . ]
