Specifications and requirements
15
cause fuel system damage or cause engine
starting and running problems. Yamaha does
not recommend gasohol containing methanol
because it can cause fuel system damage or
engine performance problems.
It is recommended that you install a water-
separating marine fuel filter assembly (10 mi-
cron minimum) between your boat’s fuel tank
and outboard motor when using ethanol. Eth-
anol is known to allow moisture to be ab-
sorbed into boat fuel tanks and systems.
Moisture in the fuel can cause corrosion of
metallic fuel system components, starting and
running complaints and require additional fuel
system maintenance.
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.
EMU40301
Outboard motor disposal re-
quirements
Never illegally discard (dump) the outboard
motor. Yamaha recommends consulting the
dealer about discarding the outboard motor.
EMU36352

there is trouble with the outboard motor.
●
A tool kit with assorted screwdrivers, pliers,

An extra engine shut-off cord (lanyard) with
