Clamping The Outboard Motor - Yamaha 8 Owner's Manual

NOTICE
Check that the idle hole stays high
G
enough to keep out water getting inside
engine even if the boat is in stationary
with maximum load.
Incorrect engine height or obstructions
G
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
airborne water spray while the boat is
cruising. If the motor is operated con-
tinuously in the presence of airborne
water spray, enough water could enter
the engine through the intake opening
on the cowling to cause severe engine
damage. Eliminate the cause of the air-
borne water spray.
TIP:
The optimum mounting height of the out-
G
board motor is affected by the boat and
motor combination and the desired use.
Test runs at different heights can help de-
termine the optimum mounting height.
Consult your Yamaha dealer or boat man-
ufacturer for further information on deter-
mining the proper mounting height.
For instructions on setting the trim angle of
G
the outboard motor, see page 36.

Clamping the outboard motor

1. Place the outboard motor on the tran-
som so that it is positioned as close to
the center as possible. Tighten the tran-
som clamp screws evenly and securely.
Occasionally check the clamp screws
for tightness during operation of the out-
board motor because they could be-

come loose due to engine vibration.
WARNING!
could allow the outboard motor to fall
off or move on the transom. This
could cause loss of control and seri-
ous injury. Make sure the transom
screws are tightened securely. Occa-
sionally check the screws for tight-
ness during operation.
2. If the restraint cable attachment is
equipped on your engine, a restraint ca-
ble or chain should be used. Attach one
end to the restraint cable attachment
and the other to a secure mounting point
on the boat. Otherwise the engine could
be completely lost if it accidentally falls
off the transom.
