Mounting height
Installation
The mounting height  of your outboard motor
affects  its  efficiency  and  reliability.   If  it  is
mounted too  high,  propeller ventilation  may
occur, which will reduce propulsion due to ex-
cessive propeller  slip, and the  cooling water
inlet for the cooling system may not  get ade-
quate water supply, which  can cause engine
overheating. If the engine is mounted too low,
water resistance (drag) will increase, thereby
reducing engine efficiency and performance.
The  optimum mounting  height  depends  on
the combination of the boat and outboard mo-
tor. Consult your Yamaha dealer or boat man-
The information presented in this section is in-
tended as reference only. It is not possible to
provide complete instructions for every possi-
ble  boat  and  outboard  motor  combination.
Proper mounting  depends in part  on experi-
ence and the specific boat and outboard mo-
tor combination.

WARNING
q
Overpowering  a  boat could  cause  se-
vere  instability. Do  not  mount an  out-
board 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
manufacturer.

NOTICE
q
Improper mounting of the outboard mo-
tor could result in hazardous conditions,
such as poor  handling, loss of  control,
or fire hazards. Have your Yamaha deal-
er mount the outboard motor properly.
q Make   sure  that  the  idle  hole  is  high
enough to  prevent water from  entering
the engine even if the boat is stationary
with the maximum load.
q
Incorrect engine height  or obstructions
to the smooth flow of water (such as the
design or  condition of  the boat,  or ac-
cessories, such  as transom  ladders or
depth finder transducers) can create air-
borne  water   spray  while  the  boat   is
cruising. If the outboard motor is operat-
ed continuously  in the presence  of air-
borne water spray,  enough water could
enter the  engine through the  air intake
opening in the top cowling to cause se-
vere engine damage. Remove the cause
of the airborne water spray.
EMU41270
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. Mount  the out-
board motor on the centerline (keel line) of the
boat.
