NOTICE

●Check that the idle hole stays high enough to keep out water getting inside engine even if the boat is in stationary with maximum load.

●Incorrect engine height or obstructions to the smooth flow of water (such as the design or condition of the boat, or ac- cessories such as transom ladders or depth finder transducers) can create air- borne water spray while the boat is cruising. If the motor is operated contin- uously in the presence of airborne water spray, enough water could enter the en- gine through the intake opening on the cowling to cause severe engine dam- age. Eliminate the cause of the airborne water spray.

TIP:

●The optimum mounting height of the out- board motor is affected by the boat and mo- tor 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 prop- er mounting height.

●For instructions on setting the trim angle of

the outboard motor, see page 35.

Clamping the outboard motor

1.Place the outboard motor on the transom so that it is positioned as close to the cen- ter as possible. Tighten the transom clamp screws evenly and securely. Oc- casionally check the clamp screws for tightness during operation of the out- board motor because they could become loose due to engine vibration.

WARNING! Loose clamp screws could

allow the outboard motor to fall off or move on the transom. This could cause loss of control and serious inju- ry. Make sure the transom screws are tightened securely. Occasionally check the screws for tightness during operation. [EWM00641]

2.If the restraint cable attachment is equipped on your engine, a restraint ca- ble or chain should be used. Attach one end to the restraint cable attachment and the other to a secure mounting point on the boat. Otherwise the engine could be completely lost if it accidentally falls off the transom.

3.Secure the clamp bracket to the transom using the bolts provided with the out- board (if packed). For details, consult your Yamaha dealer. WARNING! Avoid using bolts, nuts or washers other than those contained in the engine
