FUEL REQUIREMENTS
GASOLINE (PETROL)
Use regular unleaded 87 octane (R+M
÷ 2) gasoline (petrol).
WARNING
GASOLINE (PETROL) AND ITS
VAPORS ARE HIGHLY FLAMMABLE
AND EXPLOSIVE!
● Do not smoke when refueling, and
keep away from sparks, flames, or
other sources of ignition.
● Stop engine and turn ignition
keys to Off before refueling.
● Refuel in a well-ventilated area. If
the Jet 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
(petrol). If gasoline (petrol) spills,
wipe it up immediately 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 (petrol), inhale a lot of
gasoline (petrol) vapor, or get

● If any gasoline (petrol) spills onto
your skin, immediately wash with
soap and water. Change clothing
if gasoline (petrol) spills on it.
CAUTION:
Use only fresh gasoline (petrol) 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
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.
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 addi-
tives are important for the engines in
passenger cars, but they can have
detrimental effects in marine engines,
particularly 2-cycle engines, because
of increased deposits in the combus-
