WARNING
EWJ00282

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
ECJ00321

Do not use leaded gasoline. Leaded gas-
oline can seriously damage the engine.

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 thefuel meets the minimum octane ratings. E-85
is a fuel blend containing 85% ethanol and
therefore must not be used in this watercraft.
All ethanol blends containing more than 10%
ethanol can cause fuel system damage or en-
gine 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 45 for seat removal
and installation procedures.)
(4) Pull the visor up, and then lift up the rear
of the hood.
Recommended fuel:
Regular unleaded gasoline with a
minimum octane rating of
86
(Pump octane number) = (R + M)/2
90 (Research octane number)

Care and storage

EJU37145
Post-operation care
WARNING
EWJ00330
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 deterioration
of the jet pump and hull. Marine organisms
and corrosion are some of the conditions that
can shorten the life of many watercraft com-
ponents.
EJU33539Flushing the cooling water passages
NOTICE
ECJ01310
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 seats and seat storage com-
partment. (See page 45 for seat removal
and installation procedures and page 50
for information on the seat storage com-
partment.)(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 engine.
Immediately after the engine starts, fully
turn the water supply on so that water
