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, turn off the engine. Do
not stand or sit on the watercraft. Never
refuel while smoking, or while in the vicin-
ity of sparks, open flames, or other sourc-
es 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 23 for seat removal and
installation procedures.)
(4) Remove the fuel tank filler cap, and then
slowly add fuel to the fuel tank. Stop filling
when the fuel level reaches approximate-
ly 50 mm (2 in) from the top of the fuel
tank. Do not overfill the fuel tank. Be-
cause 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.
Recommended fuel:
Regular unleaded gasoline with a mini-
mum octane rating of
86
(Pump octane number) = (R + M)/2
90 (Research octane number)

Check the engine oil level before each use.
WARNING
EWJ00340
Engine oil is extremely hot immediately af-
ter the engine is turned off. Coming in con-
tact with or getting any engine oil on your
clothes could result in burns.
NOTICE
ECJ00391

Do not run the engine with too much or
not enough oil in the oil tank, otherwise
the engine could be damaged.

Make sure that debris and water do not
enter the oil tank filler hole. Debris and
water in the engine oil can cause serious
engine damage.
To check the engine oil level:
(1) Place the watercraft in a horizontal posi-
tion or launch the watercraft, and then
start the engine. NOTICE: When check-
ing the engine oil level on land, supply
water to the cooling water passages.
(See page 62 for procedures on sup-
plying water.)
[ECJ01020]
TIP:
When checking the engine oil level on water,
moor the watercraft so that it will not drift
away.
(2) Run the engine at trolling speed for 6 min-
utes or more, and then stop the engine.

Run the engine an additional 5 minutes if
the ambient temperature is 20 °C (68 °F)
or less.
(3) Remove the seat. (See page 23 for seat
removal and installation procedures.)
(4) Remove the oil tank filler cap, wipe the
dipstick clean, and then screw the filler
cap into the filler hole completely. Re-
move the filler cap again and check that
the engine oil level is between the mini-
mum and maximum level marks on the
dipstick.
(5) If the engine oil level is below the mini-
mum level mark, add enough oil so that
the oil level is between the minimum and
maximum level marks on the dipstick,
and then install the filler cap. If the engine
oil level is significantly above the maxi-mum level mark, the oil tank is overfilled.
Have a Yamaha dealer remove the ex-
cessive amount of engine oil.
(6) Install the seat.
EJU32420Water separator
Check the water separator for water. The wa-
ter separator retains any water that may have
entered through the fuel tank breather hose if
the watercraft was capsized. Normally, the
water separator is empty.
If water remains in the water separator, drain
it by removing the drain screw. Place a drain
pan under the water separator to catch the
draining water or use a dry cloth to soak up
any water that could spill into the watercraft. If
any water spills into the watercraft, be sure to
wipe it up with a dry cloth. Also, be sure to in-
stall the drain screw after draining the water
separator.
EJU32462Bilge

Storage
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.
Storage for long periods of time, such as win-
ter storage, requires preventive maintenance
to ensure against deterioration. It is advisable
to have the watercraft serviced by a Yamaha
dealer prior to storage. However, the following
procedures can be performed by the owner.
EJU33544Flushing the cooling system
Flushing the cooling system is essential to
prevent it from clogging with salt, sand, or dirt.
(1) Place the watercraft in a horizontal posi-
tion.
(2) Remove the seat. (See page 23 for seat
removal and installation procedures.)
(3) Remove the flushing hose connector
cap, and then insert the garden hose
adapter into the flushing hose connector
and turn it until it is securely connected.
(4) Connect the garden hose adapter to a
water tap using a garden hose.

A garden hose is not included.
(5) Start the engine, and then immediately
turn the water supply on until water flows
out continually from the jet thrust nozzle.
NOTICE: Do not run the engine for
more than 15 seconds without supply-
ing water or over 4000 r/min on land,
otherwise the engine could overheat.
[ECJ01050]
TIP:
If you will be storing the watercraft for a pro-
longed period, such as winter storage, top off
the fuel tank with fresh gasoline and add fuel
stabilizer and conditioner to the fuel tank ac-
cording to the manufacturer’s instruction be-
fore starting the engine.
(6) Run the engine at idling speed for about
3 minutes watching the engine condition.
If the engine stops while flushing, turn the
water supply off immediately and repeat
the above steps. NOTICE: Do not sup-
ply water to the cooling water passag-
es when the engine is not running. The
water could flow back through the
muffler into the engine, causing se-
vere engine damage.
