CAUTION:
Improper mounting of the outboard motor
could result in hazardous conditions such
as poor handling, loss of control, or fire
hazards. Observe the following:
Incorrect engine height or obstructions to
smooth water flow (such as the design or
condition of the boat, or accessories such
as transom ladders or depth finder trans-
ducers) can create airborne water spray
while the boat is cruising. Severe engine
damage may result if the motor is operat-
ed continuously in the presence of air-
borne water spray.
q
For permanently mounted models, your
dealer or other person experienced in
proper rigging should mount the motor.
If you are mounting the motor yourself,
you should be trained by an experienced
person.
q
For portable models, your dealer or oth-
er person experienced in proper out-
board motor mounting should show you
how to mount your motor.
NOTE:
During water testing check the buoyancy of
the boat, at rest, with its maximum load.

Mounting height (boat bottom)
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
