ly available gasoline and environmental con-
ditions.
EMU36881
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.
EMU41354
Anti-fouling paint
A clean hull is required to maintain your
boat’s performance. Boats moored in the wa-
ter should be protected from marine growth
(barnacles, mussels, and marine plants). If
approved by regulations for your area, the
bottom of the hull can be coated with an anti-
fouling paint to inhibit marine growth.
Anti-fouling paints specifically formulated for
use on aluminum may be applied to the out-
board motor. The original Yamaha paint sur-
face may be scuffed lightly before applying
anti-fouling paint, but do not remove the orig-
inal paint. Removal of the original paint will in-
crease the rate of corrosion.

z
Anti-fouling paint for fiberglass and
wood may contain materials, such as
copper, graphite, and tin, that can cause
corrosion if applied to aluminum boats
and outboard motor components. Never
apply these types of paint to your out-
board motor because rapid corrosion
damage could occur.
z
Anti-fouling paint can increase drag
(friction) between the boat and the wa-
ter, and possibly affect performance. If
the effects are too great, reducing pro-
peller pitch may be necessary.
Sacrificial anodes are attached to the out-
board motor to provide corrosion protection
and must never be painted.
Sacrificial anodes made from a different ma-
terial may be necessary for maximum corro-
sion protection due to your local water
conditions. Please consult your Yamaha
dealer.
NOTICE
ECM02421
Painted sacrificial anodes will not provide
corrosion protection.
EMU40302
Outboard motor disposal re-
quirements
Never illegally discard (dump) the outboard
motor. Yamaha recommends consulting the
dealer about discarding the outboard motor.
EMU36353
Emergency equipment
Keep the following items onboard in case
there is trouble with the outboard motor.
z
A tool kit with assorted screwdrivers, pliers,
wrenches (including metric sizes), and
electrical tape.

Waterproof flashlight with extra batteries.
