WARNING
EWJ00283
Gasoline and gasoline vapors are ex-
tremely flammable. To avoid fires and
explosions and to reduce the risk of in-
jury when refueling, follow these in-
structions.
Gasoline is poisonous and can cause in-
jury or death. Handle gasoline with care.
Never siphon gasoline by mouth. If you
should swallow some gasoline, inhale a
lot of gasoline vapor, or get some gaso-
line in your eyes, see your doctor imme-
diately. If gasoline spills on your skin,
wash with soap and water. If gasoline
spills on your clothing, change your
clothes.
NOTICE
ECJ00322
Do not use leaded gasoline. Leaded
gasoline can seriously damage the en-
gine.
Avoid getting water and contaminants in
the fuel tank. Contaminated fuel can
cause poor performance and engine
damage. Use only fresh gasoline that
has been stored in clean containers.
Gasohol
There are two types of gasohol: gasohol con-
taining ethanol and that containing methanol.Gasohol containing ethanol can be used if
ethanol content does not exceed 10% and
the fuel meets the minimum octane ratings.
E-85 is a fuel blend containing 85% ethanol
and therefore must not be used in this water-
craft. All ethanol blends containing more than
10% ethanol can cause fuel system damage
or engine performance problems.
Yamaha does not recommend gasohol con-
taining methanol because it can cause fuel
system damage and engine performance
problems.
To fill the fuel tank:
(1) Before refueling, stop the engine. Do not
stand or sit on the watercraft. Never refu-
el while smoking, or while in the vicinity
of sparks, open flames, or other sources
of ignition.
(2) Place the watercraft in a well-ventilated
area and in a horizontal position.
(3) Remove the seats, and then check the
fuel level. (See page 48 for seat removal
and installation procedures.)
(4) Pull the hood latch rearward, and then lift
up the rear of the hood.
Recommended fuel:
Regular unleaded gasoline with a mi-
nimum octane rating of

(5) Loosen the fuel filler cap and remove it.
(6) Slowly add fuel to the fuel tank.
(7) Stop filling when the fuel level reaches
approximately 50 mm (2 in) from the top
of the fuel tank. Do not overfill the fuel
tank. Because fuel expands when it
heats up, heat from the engine or the sun
can cause fuel to spill out of the fuel tank.Do not leave the watercraft with a full
tank in direct sunlight.
(8) Wipe up any spilled fuel immediately with
a dry cloth.
(9) Securely install the fuel filler cap by tight-
ening it until it clicks.
