To run your boat at optimum efficiency, the
water resistance (drag) of the boat and out-
board motor must be made as little as possi-
ble. 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 en-
gine 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 between the bottom of the boat and
a level 25 mm (1 in) below it.

have a capacity plate, consult the boat
manufacturer.
Improper mounting of the outboard mo-
tor could result in hazardous condi-
tions such as poor handling, loss of
control, or fire hazards. For permanent-

WARNING
Your dealer or other person experienced
in
proper outboard motor mounting
should show you how to mount your out-
board motor.
The outboard motor should be mounted so
that the boat is well balanced. Otherwise, the
boat could be hard to steer. For single-en-
gine boats, mount the outboard motor on the
centerline (keel line) of the boat.
