[. . . ] VZ200 VZ225 VZ250 VZ300 OWNER'S MANUAL U. S. A. Edition LIT-18626-07-03 6C9-28199-14 EMU25071 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. 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 1 1. Center line (keel line) EMU26950 ZMU01873 Mounting height 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 32 Operation motor greatly affects the water resistance. If the mounting height is too high, cavitation tends to occur, thus reducing the propulsion and causing 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 about 130 mm (5 in. ) above the bottom of the boat. G G could result in reduced engine life or even severe engine damage. Do not use premixed fuel in this engine because it could cause carbon deposits on the fuel injector and engine trouble. Follow the instructions for break-in carefully. NOTE: Leave the label pictured below on the top cowling until the break-in procedure has been completed. It may be removed afterwards. 130mm ( 5 in. ) ZMU02098 NOTE: G G The optimum mounting height of the outboard motor is affected by the boat and 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 42. EMU27041 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 life. ECM00750 ZMU01945 EMU27091 Procedure for HPDI models Run the engine under load (in gear with a propeller installed) for 10 hours as follows. [. . . ] Release the switch when oil reaches the upper level line on the engine oil tank. Do not use this emergency procedure unless the oil level warning indicators are working. Turn on the main switch. ZMU01907 1. Remote oil tank 2 ZMU01908 4. After using the emergency switch, turn off the main switch, then turn it back on. [. . . ]
