than the maximum rating on the capac-    Mounting height
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.
ity plate of the boat. If the boat does not
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-
ly mounted models, your dealer or oth-
q
er
person
experienced
in
proper
rigging should mount the motor.

Mounting the outboard 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.
