CHECKING BOLTS AND NUTS

1)

Check that bolts securing the cylinder
head and engine and the nut securing
the flywheel are tightened with their
specified tightening torque.

2)

Check the tightening torque of other
bolts and nuts.

MOTOR EXTERIOR

EMU00410

Cleaning the Outboard Motor

After use, wash the exterior of the out-
board with fresh water.
Flush the cooling system with fresh
water.

NOTE:

Refer to Flushing Cooling System instruc-
tions in “TRANSPORTING AND STORING
OUTBOARD MOTOR”.

EMU00412

Checking Painted Surface of Motor

Check the motor for scratches, nicks, or
flaking paint. Areas with damaged paint
are more likely to corrode. If necessary,
clean and paint the areas. A touch-up
paint is available from a Yamaha dealer.

EMU00413

COATING THE BOAT BOTTOM

A clean hull improves boat performance.
The boat bottom should be kept as clean
of marine growths as possible. If neces-
sary, the boat bottom can be coated with
an anti-fouling paint approved for your
area to inhibit marine growth.
Do not use anti-fouling paint which
includes copper or graphite. These paints
can cause more rapid engine corrosion.
