Clamping The Outboard Motor - Yamaha 40V Owner's Manual

ECM01630
NOTICE
During water testing, check the buoy-
●
ancy of the boat, at rest, with its maxi-
mum load. Check that the static water
level on the exhaust housing is low
enough to prevent water entry into the
power head when water rises due to
waves when the outboard is not run-
ning.
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
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.

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 engine restraint cable attachment
is equipped on your engine, an engine
restraint cable or chain should be used.
Attach one end to the engine restraint
cable attachment and the other to a se-
cure mounting point on the boat. Other-
wise the engine could be completely lost
if it accidentally falls off the transom.
3. Secure the clamp bracket to the transom
using the bolts provided with the out-
board (if packed). For details, consult
