NOTE:
●
The optimum mounting height of the out-
board motor is affected by the boat and mo-
tor combination and the desired use. Test
runs at different heights can help determine
the optimum mounting height. Consult your
Yamaha dealer or boat manufacturer for
further information on determining the prop-
er mounting height.
●
For instructions on setting the trim angle of
the outboard motor, see page 48.

Clamping the outboard motor
1.
Place the outboard motor on the transom
so that it is positioned as close to the cen-
ter as possible. Tighten the transom
clamp screws evenly and securely. Oc-
casionally check the clamp screws for
tightness during operation of the out-
board motor because they could become
loose due to engine vibration.
WARNING
EWM00640
Loose clamp screws could allow the out-
board motor to fall off or move on the tran-
som. This could cause loss of control and
serious injury. Make sure the transom
screws are tightened securely. Occasion-
ally check the screws for tightness during
operation.
2.
If the engine restraint cable attachment is
equipped on your engine, an engine re-
straint cable or chain should be used. At-
tach one end to the engine 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.
3.
Secure the clamp bracket to the transom
using the bolts provided with the out-
board (if packed). For details, consult
your Yamaha dealer.
WARNING
EWM00650
Avoid using bolts, nuts or washers other
than those contained in the engine pack-
aging. If used, they must be of at least the
same quality of material and strength and
must be tightened securely. After tighten-
ing, test run the engine and check their
tightness.
