maximum engine speed is limited.
If the oil pressure warning is activated, imme-
diately reduce the engine speed, return to
shore, and then check the engine oil level.
(See page 51 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.

EJU37303Engine overheat warning
If the engine temperature rises significantly,
the engine overheat warning indicator and the
“WARNING” indicator light blink, and the
buzzer sounds intermittently. Then, the en-
gine overheat warning indicator and the
“WARNING” indicator light stop blinking and
remain on, and the buzzer sounds continu-
ously. At the same time, the maximum engine
speed is limited.If the engine overheat warning is activated,
immediately reduce the engine speed, return
to shore, and then make sure that water is be-
ing discharged from the port (left) cooling wa-
ter pilot outlet while the engine is running. If
there is no discharge of water, stop the en-
gine, and then check the jet intake for clog-
ging. (See page 92 for information on the jet
intake.) NOTICE: If you cannot locate and
correct the cause of the overheating, con-
sult a Yamaha dealer. Continuing to oper-
ate at higher speeds could result in severe
engine damage.

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 41 for seat removal
and installation procedures.)
(4) Push the hood latch, 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)

(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. Donot 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.
(10) Push the rear of the hood down to se-
curely lock it in place. Make sure that the
fuel filler cap and the hood are securely
closed before using the watercraft.
(11) Securely install the seats in their original
positions.

NOTICE
ECJ00281
Use only 4-stroke engine oil. Usage of 2-
stroke engine oil could result in severe en-
gine damage.
Checking the engine oil level
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
ECJ01001
Make sure that debris and water do not en-
ter the oil 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 precisely level
position on land with the engine stopped.
If the engine was running, allow the en-
gine oil to settle by waiting 5 minutes or
more before checking the oil level.
(2) Remove the seats. (See page 41 for seat
removal and installation procedures.)(3) Remove the dipstick and wipe it clean.
(4) Insert the dipstick back into the dipstick
tube completely. Remove the dipstick
again and make sure that the engine oil
level is between the minimum and maxi-
mum level marks.
(5) If the engine oil level is significantly above
the maximum level mark, consult a
Yamaha dealer. If the engine oil level is
below the minimum level mark, add en-
gine oil. Recommended engine oil type:
SAE 10W-30, 10W-40, 20W-40, 20W-

(6) Loosen the engine oil filler cap and re-
move it.
(7) Slowly add engine oil.
TIP:
The difference between the minimum and
maximum level marks on the dipstick is equal
to approximately 1 L (1.06 US qt, 0.88 Imp. qt)
of engine oil.
(8) Wait approximately 5 minutes to allow the
engine oil to settle, and then check the
engine oil level again.
(9) Repeat steps 3–8 until the engine oil is at
the proper level.
(10) Securely install the engine oil filler cap by
tightening it until it stops.
(11) Securely install the seats in their original
positions.

Draining the bilge water
NOTICE
ECJ01301
Do not run the engine at full throttle when
bilge water remains in the engine compart-
ment. The bilge water can splash into the

To drain the bilge water on land:
(1) Loosen the stern drain plugs and remove
them.
(2) Raise the bow of the watercraft, such as
by placing the watercraft on a slope, to
drain the bilge water from the engine
compartment.
(3) After the bilge water has drained from the
stern drain plug holes, wipe up any re-1Engine oil filler cap
