Gasoline Additives
Gasoline blends change to meet automobile
emission regulations and economic condi-
tions. Additives, added by gasoline distribu-
tors, necessary for proper automobile engine
operation and durability, may not be sufficient
for typical boat applications. Intake valve and
combustion chamber deposits may accumu-
late in boat engines more rapidly than en-
countered in automotive use. In addition,
gasoline used for boating will typically age
longer between refills than gasoline used in
automobiles, resulting in stale and unusable
gasoline that may cause starting and running
problems, fuel system damage, and internal
engine damage.
Yamaha recommends the use of two Ya-
malube gasoline additives to reduce internal
deposits and extend the storage life of gaso-
line. Continuous use of Yamalube Ring Free
Fuel Additive Plus reduces harmful internal
deposits. Yamalube Fuel Stabilizer & Condi-
tioner Plus added to fresh gasoline will help
protect the fuel system from varnishing while
helping to keep the gasoline’s octane level
from decreasing excessively during storage.
Other additives may also be available on the
market that may have varying degrees of ef-
fectiveness. Consult your Yamaha dealer
concerning what may work best for the locally
available gasoline and environmental condi-
tions.

Anti-fouling paint
A clean hull is required to maintain your boat’s
performance. Boats moored in the water
should be protected from marine growth (bar-
nacles, mussels, and marine plants). If ap-
proved 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 origi-
nal paint. Removal of the original paint will in-
crease the rate of corrosion.
ECM02410
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 outboard motor be-
cause rapid corrosion damage could oc-
cur.
Sacrificial anodes are attached to the out-
board motor to provide corrosion protection
and must never be painted.
ECM02420
Painted sacrificial anodes will not provide
corrosion protection.
EMU40301
Outboard motor disposal re-
quirements
Never illegally discard (dump) the outboard
motor. Yamaha recommends consulting the
dealer about discarding the outboard motor.
