Clamping The Outboard Motor - Yamaha 2D Owner's Manual

Installation
ECM01635
NOTICE
 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.
 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 oper-
ated 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.
TIP:
 The optimum mounting height of the out-
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
the outboard motor, see page 27.

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 clamp
screws evenly and securely. Occasional-
ly check the clamp screws for tightness
during operation of the outboard motor
because they could become loose due
to engine vibration. WARNING! Loose
clamp screws could allow the out-
19
board motor to fall off or move on the
transom. This could cause loss of
control and serious injury. Make sure
the clamp screws are tightened se-
curely. Occasionally check the screws
for tightness during operation.
2. Attach one end to the restraint cable at-
tachment 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.
