CAUTION:

Be sure the cowling is closed securely

and that there are no gaps. A loose or im-

properly fitting cover could allow water

into the engine.

Check the fitting of the top cowling by push-

ing it with both hands. If it is loose have it re-

paired by your Yamaha dealer.

A clean hull improves boat performance. The

boat bottom should be kept as clean of ma-

rine growth as possible. If necessary, the

boat bottom can be coated with an anti-foul-

ing 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.
