Overpowering a  boat may  cause severe
instability.   Do not  install   an outboard
motor  with more  horsepower  than  the
maximum rating on  the capacity plate of
the  boat.  If  the  boat  does  not  have  a
capacity plate, consult the boat  manufac-
turer.

Mounting Height
To run  your boat  at optimum  efficiency,
the  water-resistance   (drag)  of the  boat
and outboard motor must  be made as lit-
tle as  possible.  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 pro-
peller  tips cut  the air,  the engine  speed
will rise abnormally and cause the  engine
to overheat. If  the mounting-height is too
low,  the  water-resistance   will  increase
and  thereby  reduce   engine  efficiency.
Mount the  engine so  that the anti-cavita-
tion plate is in alignment  with the bottom
of the boat .

The  optimum mounting  height  of  the
outboard    motor  is   affected   by  the
boat/motor  combination.  Test  runs at
different heights can help determine the
optimum mounting height.

Refer to  the section  “TRIMMING OUT-
BOARD  MOTOR”  for  instructions   on
setting the trim angle of the outboard.
