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.

head and engine and the nut securing
the flywheel are tightened with their
specified tightening torques.
2) Check the tightening torques of other
bolts and nuts.
