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.

To run  your boat  at optimum  efficiency, the
water resistance  (drag) of the  boat and out-
