 Make sure that the idle hole is high
enough to prevent water from entering
the engine even if the boat is stationary
with the 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
airborne water spray while the boat is
cruising. If the outboard motor is oper-
ated continuously in the presence of
airborne water spray, enough water
could enter the engine through the air
intake opening in the top cowling to
cause severe engine damage. Remove
the cause of the airborne water spray.
TIP:
 The optimum mounting height of the out-
board motor is affected by the boat and
motor combination and the desired use.
Test runs at different heights can help de-
termine the optimum mounting height.
Consult your Yamaha dealer or boat man-
ufacturer for further information on deter-
mining the proper mounting height.
 For instructions on setting the trim angle of
the outboard motor, see page 66.
