[. . . ] F200 LF200 F225 LF225 OWNER'S MANUAL U. S. A. Edition LIT-18626-07-15 69J-28199-17 ZMU01690 Read this owner's manual carefully before operating your outboard motor. 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. [. . . ] G For portable models, your dealer or other person experienced in proper outboard motor mounting should show you how to mount your motor. Mount the outboard motor on the center line (keel line) of the boat, and ensure that the boat itself is well balanced. Otherwise the boat will be hard to steer. For boats without a keel or which are asymmetrical, consult your dealer. CAUTION: 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 continuously in the presence of airborne water spray. NOTE: During water testing check the buoyancy of the boat, at rest, with its maximum load. Check that the static water level on the exhaust housing is low enough to prevent water entry into the powerhead, when water rises due to waves when the outboard is not running. EMU26910 Mounting the outboard motor EWM00820 WARNING G G Overpowering a boat could cause severe instability. Do not install an outboard motor with more horsepower than the maximum rating on the capacity plate of the boat. If the boat does not have a capacity plate, consult the boat manufacturer. 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 specific boat and motor combination. 1 1. Center line (keel line) ZMU01760 35 Operation NOTE: G 1. Center line (keel line) EMU26930 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 43. 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 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. EMU30173 Breaking in engine Your new engine requires a period of break-in to allow mating surfaces of moving parts to wear in evenly. Correct break-in will help ensure proper performance and longer engine 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. [. . . ] G There will be fuel in the fuel filter. Keep away from sparks, cigarettes, flames or other sources of ignition. 76 Trouble Recovery NOTE: Properly dispose of the rag. Firmly screw the filter cup onto the filter housing. NOTE: Be careful not to twist the water detection switch lead when screwing the filter cup onto the filter housing. Connect the water detection switch coupler securely until a click is heard. 1.
