EJU37272Fuel level meter
The fuel level meter shows the amount of fuel
remaining in the fuel tank. The amount of re-
maining fuel is shown using four display seg-
ments, which disappear one at a time as the
fuel level decreases.
TIP:
The accuracy of the fuel level meter varies
depending on the operating conditions. Use
this function as a reference only.
EJU44711Fuel level warning
If the fuel remaining in the fuel tank drops to
about 18 L (4.8 US gal, 4.0 Imp.gal), the low-
est fuel level segment, the fuel level warning
indicator, and the “WARNING” indicator lightblink, and the buzzer sounds intermittently for
30 seconds.
If the fuel level warning is activated, refill the
fuel tank as soon as possible. (See page 62
for information on filling the fuel tank.)
After the fuel tank is refilled, the warning sig-
nals will be cleared when the engine is re-
started.
EJU43720Oil pressure warning
If the oil pressure drops significantly, the oil
pressure warning indicator, the check engine
warning indicator, and the “WARNING” indi-
cator light blink, and the buzzer sounds inter-
mittently for 30 seconds. At the same time,
the 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 64 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.

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.
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.
TIP:
This mark identifies the recommended fuel
for this watercraft as specified by European
regulation (EN228).
Check that the gasoline nozzle has the
same identifier when fueling.
Gasohol
There are two types of gasohol: gasohol con-
taining ethanol and gasohol containing meth-
anol.
Gasohol containing ethanol can be used if
the ethanol content does not exceed 10%
and the fuel meets th e minimum octane rat-
ings. E-85 is a fuel blend containing 85% eth-
anol and therefore must not be used in this
watercraft. All ethanol blends containing
more than 10% ethanol can cause fuel sys-
tem damage or engine performance prob-
lems.
Yamaha does not recommend gasohol con- taining methanol because it can cause fuel
system damage and engine performance
problems. Recommended fuel:
Regular unleaded gasoline with a
minimum octane rating of 86
(Pump octane number) = (R + M)/2
90 (Research octane number)

To fill the fuel tank:
(1) Before refueling, stop the engine. Do notstand 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 54 for seat removal
and installation procedures.)
(4) Loosen the fuel filler cap and remove it.
(5) Slowly add fuel to the fuel tank.
(6) 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.
(7) Wipe up any spilled fuel immediately with a dry cloth.
(8) Securely install the fuel filler cap by tight- ening it until it clicks.
(9) Securely install the seats in their original positions.
