methanol. Ethanol can be used if the ethanol
content does not exceed 10% and the fuel
meets the minimum octane ratings. All etha-
nol blends containing more than 10% etha-
nol can cause fuel system damage or cause
engine starting and running problems.
Yamaha does not recommend gasohol con-
taining methanol because it can cause fuel
system damage or engine performance
problems.

Muddy or acidic water
Yamaha strongly recommends that you have
your dealer install the optional chromium-
plated water pump kit if you use the outboard
motor in muddy or acidic water conditions.
However, depending on the model it might
not be required.

Anti-fouling paint
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.
