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 seat, and then check the
fuel level. (See page 34 for seat removal
and installation procedures.)
(4) Loosen the fuel filler cap and remove it.
(5) Slowly add fuel to the fuel tank. Recommended fuel:
Regular unleaded gasoline with a
minimum octane rating of
86
(Pump octane number) = (R + M)/2
90 (Research octane number)

Post-operation care
WARNING
EWJ00331
Always place the watercraft upright in a
horizontal position when storing it, other-
wise fuel could leak out into the engine or
engine compartment, which could create
a fire hazard.
After using the watercraft, always take it out
of the water, clean it, and store it. Leaving the
watercraft in the water for extended periods
will accelerate the rate of normal deteriora-
tion of the jet pump and hull. Marine organ-
isms and corrosion are some of the
conditions that can shorten the life of many
watercraft components.
EJU33548Flushing the cooling water passages
NOTICE
ECJ01311
Do not run the engine over 4000 r/min on
land. Also, do not run the engine for more
than 15 seconds without supplying water,
otherwise the engine could overheat.
Flush the cooling water passages to prevent
them from clogging with salt, sand, or dirt.
(1) Place the watercraft in a horizontal posi-
tion.
(2) Remove the seat. (See page 34 for seat
removal and installation procedures.)(3) Connect the garden hose adapter to a
garden hose.
(4) Loosen the flushing hose connector cap
and remove it. Insert the garden hose
adapter into the flushing hose connector
and turn it until it is securely connected.
(5) Connect the garden hose to a water tap.
(6) Make sure that the area around the wa-
tercraft is clear, and then start the en-
gine. Immediately after the engine starts,
fully turn the water supply on so that wa-
