wear in evenly. Correct break-in will help en-

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
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  in alignment with  the bottom  of the
boat.

CAUTION:
q Failure to follow the break-in procedure
could  result in  reduced engine  life  or
even severe engine damage.
q Do not use premixed fuel in this engine
because it  could cause carbon  depos-
its on the fuel injector and engine trou-
ble.
q Follow   the   instructions  for   break-in
carefully.
NOTE:
Leave  the label  pictured  below on  the  top

been completed.  It  may be  removed after-
