FUEL AND OIL
GASOLINE
Use regular unleaded 87 octane (R+M
÷ 2) gasoline.
GASOLINE AND ITS VAPORS ARE
HIGHLY FLAMMABLE AND EXPLO-
SIVE!
Do not smoke when refueling,
and keep away from sparks,
flames, or other sources of igni-
tion.
Stop engines and turn ignition
keys to Off before refueling.
Refuel in a well-ventilated area. If
the Sport Boat is in the water, be
sure it is securely moored to the
fueling dock. All passengers
must be out of the boat during
refueling.
Take care not to spill gasoline. If
gasoline spills, wipe it up imme-
diately with dry rags. Always
properly dispose of gasoline-
soaked rags.
Avoid overfilling the fuel tank.
Stop filling when the fuel level
just reaches the bottom of the
filler tube. Do not fill up the filler
tube because fuel expands as it
warms up and could overflow.
Tighten the filler cap securely
after refueling.
If you should swallow some
gasoline, inhale a lot of gasoline
vapor, or get gasoline in your
eyes, get immediate medical
attention.
If any gasoline spills onto your
skin, immediately wash with soap
and water. Change clothing if
gasoline spills on it.
Use only fresh gasoline that has
been stored in clean containers.
Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that con-
taining methanol. Gasohol containing
ethanol can be used if ethanol content
does not exceed 10% and the fuel
meets minimum octane ratings.
Gasohol containing methanol is not
recommended by Yamaha because it
can cause fuel system damage or
engine performance problems.
Ring Free Fuel Additive
Gasoline is a precise blend of many dif-
ferent substances, each chosen to give
certain characteristics. Gasoline
blends have been changing in recent
years in response to concerns about
pollution and resulting emissions regu-
lations. One of the most obvious
changes has been the elimination of
lead from fuels.
As gasoline has changed, the amount
of additives such as aromatics and
oxygenates has increased. These
additives are important for the engines
in passenger cars, but they can have
detrimental effects in marine engines.
