about 13 L (3.4 US gal, 2.9 Imp gal), the
lowest two fuel level segments, the fuel
warning indicator and the warning light
begin to blink. The buzzer also starts sound-
ing intermittently.
The warning signals will be cleared when
the engine restarts after refilling fuel.
EJU01034
Oil warning indicator
If the oil remaining in the tank drops to
about 1.7 L (0.45 US gal, 0.37 Imp gal) or
the oil filter is clogged, the oil warning indi-
cator and the warning light begin to blink.
The buzzer also starts sounding intermit-
tently.
If the oil warning indicators begin to blink,
refill with engine oil as soon as possible.
The warning signals will be cleared when
the engine restarts after refilling engine oil.
NOTE:@ If the warning indicators blink with adequate
oil in the tank, check the oil filter for clog-
ging.

Engine overheat warning
indicator
If the engine starts to overheat, the warn-
ing light and engine overheat warning indi-
cator begin to blink, and the buzzer sounds
intermittently.
If the watercraft continues to be operated
at higher speeds after the warning system
has been activated, the warning light,
engine overheat warning indicator and the
buzzer will change from intermittently to
continuously on. (See “Engine overheat
warning system” on pages 2-13 to 2-14 for
further details.)
The warning signals will turn off when the
engine is started after it has cooled down.
NOTE:@ When the warnings overlap each other, their
priority is as follows:
1. Final overheat warning
2. Fuel level warning
3. Oil level warning
4. Initial overheat warning

Yamaha Adjustable Sponson
(Y.A.S.)
The sponsons 1 have adjustable posi-
tioning to allow the operator to enhance
either straight-line performance or turning
performance according to the preference
and operating conditions.
Adjusting to upward A:
There will be less water resistance in this
position, so straight-ahead acceleration
when on plane and top speed will be
enhanced.
Adjusting to downward B:
This position will give the watercraft more
“hook” which will enhance turning perfor-
mance.

Fuel and oil
This engine uses Yamaha’s oil injection
system, which provides superior lubrication
by ensuring the proper oil ratio for all operat-
ing conditions. No fuel premixing is neces-
sary except during the engine break-in
period. Simply pour gasoline into the fuel
tank and oil into the oil tank.
EJU01042
Gasoline
WARNING@ GASOLINE AND ITS VAPORS ARE
HIGHLY FLAMMABLE AND EXPLOSIVE!

Do not smoke when refueling, and
keep away from sparks, flames, or
other sources of ignition.

Stop engine before refueling.

Refuel in a well-ventilated area. Do not
stand or sit on the watercraft while
refueling in case of fire.

Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags. Always properly dispose of
gasoline-soaked rags.

Avoid overfilling the fuel tank. Stop fill-
ing when the fuel level just reaches the
bottom of the filler tube. Do not fill up
the filler tube because fuel expands as
it warms up and could overflow.

Tighten the filler cap securely after
refueling.

If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.

If any gasoline spills onto your skin,
immediately wash with soap and
water. Change clothing if gasoline
spills on it.

CAUTION:@ Use only fresh gasoline that has been
stored in clean containers.

EJU01043
Gasohol
There are two types of gasohol: gasohol
containing ethanol and that containing meth-
anol.
Gasohol containing ethanol can be used
if ethanol content does not exceed 10 % and
the fuel meets minimum octane ratings.
Gasohol containing methanol is not rec-
ommended by Yamaha because it can
cause fuel system damage or engine perfor-
mance problems.
EJU01044
2-stroke engine oil
If YAMALUBE 2-W is not available,
another 2-stroke engine oil with an NMMA-
certified TC-W3 rating may be used.Recommended gasoline:
Regular unleaded gasoline with
a minimum octane rating of
86 (Pump octane number) = (R+M)/2
90 (Research octane number)
Recommended engine oil:
YAMALUBE 2-W

Filling the fuel tank
CAUTION:@ Be careful when refueling. Avoid getting
water or other contaminants in the fuel
tank. Contaminated fuel can cause poor
running or engine damage.
@
1. Open the hood and remove the front
storage compartment, to check the fuel
level. (See page 2-20 for front storage
compartment.)
2. Open the fuel tank filler cap, and slowly
add fuel to the fuel tank.
3. Stop filling when the fuel just reaches the
bottom of the filler tube on the fuel tank.
Do not fill into the filler tube, because
fuel could spill out.
Fuel tank capacity:
Total: 60 L (15.9 US gal, 13.2 Imp gal)
Reserve: 10 L (2.64 US gal, 2.20 Imp gal)
