NOTICE

ECM01981

●

Do not use leaded gasoline. Leaded gas-
oline can seriously damage the engine.

●

Avoid getting water and contaminants in
the fuel tank. Contaminated fuel can
cause poor performance or engine dam-
age. Use only fresh gasoline that has
been stored in clean containers.

EMU36880

Muddy or acidic water

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

EMU36330

Anti-fouling paint

A clean hull improves boat performance. The
boat bottom should be kept as clean of marine
growth as possible. If necessary, the boat bot-
tom 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.

EMU36341

Motor disposal requirements

Never illegally discard (dump) the motor.
Yamaha recommends consulting the dealer
about discarding the motor.
