speeds. If this occurs, the “WARNING” light
and the engine overheat warning indicator
come on and the buzzer sounds continuously.
In addition, the warning system will cut the ig-
nition to the engine to reduce the risk of se-
vere overheating. The engine cannot be
started until it cools down, so it may be neces-
sary to have the watercraft towed back to the
shore. (See “Towing the watercraft” on page
78 for towing procedures.)
The warning signals will be cleared when the
engine is restarted after it has cooled down.
NOTE:
If multiple warnings occur at the same time,
their priority is as follows:
(1) Final engine overheat warning
(2) Fuel level warning
(3) Oil level warning
(4) Initial engine overheat warning
(5) Exhaust temperature warning
(6) Check engine warning
EJU31610Exhaust temperature warning indicator
This model is equipped with an exhaust tem-
perature warning system.
If the exhaust temperature becomes too hot,
the “WARNING” light and the exhaust tem-
perature warning indicator begin to blink, and
the buzzer sounds intermittently.If this occurs, reduce the engine speed and
return to shore to allow the exhaust system to
cool down.
WARNING
EWJ00830
Do not touch the hot muffler or catalytic
converter during or immediately after en-
gine operation; they can cause serious
burns. In addition, the catalytic converter
becomes hotter after the engine stops be-
fore cooling down.
CAUTION:
ECJ00810
This model is equipped with a catalytic
converter.

If the “WARNING” light, exhaust temper-
ature warning indicator, and buzzer
come on, reduce the engine speed (be-
low 4000 r/min) and return to shore.

If you cannot locate and correct the
cause of the overheating, consult a
Yamaha dealer. Continuing to operate at
higher speeds could result in severe en-
gine damage.
The warning signals will be cleared when the
engine is restarted after it has cooled down.
EJU31630Check engine warning indicator
If a sensor malfunction or a short circuit is de-
tected, the “WARNING” light and the check

If this occurs, reduce the engine speed, return
to shore, and have a Yamaha dealer check
the engine.

Fuel and oil
This engine uses Yamaha’s oil injection sys-
tem, which provides superior lubrication by
ensuring the proper fuel-to-oil ratio for all op-
erating conditions. No fuel premixing is nec-
essary, except during the engine break-in
period. Simply pour gasoline into the fuel tank
and oil into the oil tank.
The engine utilizes an electronic fuel injection
system to deliver the optimal air-fuel ratio re-
quired by the engine. By ensuring the optimal
combustion conditions, this system is able to
increase startability and improve fuel econo-
my.
EJU31850Gasoline
WARNING
EWJ00440
GASOLINE AND ITS VAPORS ARE HIGH-
LY FLAMMABLE AND EXPLOSIVE!

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

Stop the engine before refueling.

Refuel in a well-ventilated area with the
watercraft in a horizontal position.

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. If tempo-
rarily leaving the watercraft with a full
fuel tank, do not leave it in direct sun-
light. Leave it in a well-ventilated areawith the watercraft in a horizontal posi-
tion.

Tighten the fuel tank filler cap securely
after refueling.

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

If any gasoline spills on your skin or
clothing, immediately wash the affected
area with soap and water and change
your clothes.
CAUTION:
ECJ00320

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

Use only fresh gasoline that has been
stored in clean containers.
EJU31860Gasohol
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 the
fuel meets the minimum octane ratings.
Gasohol containing methanol is not recom-
mended by Yamaha because it can cause
fuel system damage and engine performance
problems.Recommended gasoline:
Regular unleaded gasoline with a mini-
mum octane rating of
86 (Pump octane number) = (R +
M)/2
90 (Research octane number)

EJU318802-stroke engine oil
CAUTION:
ECJ00270
Use only YAMALUBE 2-W engine oil, oth-
erwise the catalytic converter and other
engine components could be seriously
damaged.
NOTE:
YAMALUBE 2-W engine oil is developed for
this watercraft and available from a Yamaha
dealer.
EJU31920Filling the fuel tank
CAUTION:
ECJ00290
Be careful when refueling. Avoid getting
water and other contaminants in the fuel
tank. Contaminated fuel can cause poor
running and engine damage.
(1) Open the hood, remove the front storage
compartment, and then check the fuel
level. (See “Front storage compartment”
on page 32 for more information.)
(2) Remove the fuel tank filler cap, and then
slowly add fuel to the fuel tank. Stop fillingwhen the fuel level just reaches the bot-
tom of the filler tube.
(3) Install the fuel tank filler cap and front
storage compartment, and then close the
hood.
NOTE:
Do not fill up the filler tube because fuel ex-
pands as it warms up and could overflow.
EJU31960Filling the oil tank
WARNING
EWJ00420

Do not add gasoline to the oil tank. Fire
or explosion could result.

Oil in the bilge is a serious fire hazard.
Wipe up any spilled oil immediately.
CAUTION:
ECJ00300
Do not allow the oil tank to become com-
pletely empty. If the oil tank becomes emp-
ty, the oil pump must be bled to ensure
proper oil flow, otherwise engine damage
could result. If necessary, have a Yamaha
dealer bleed the oil pump.
(1) Remove the seat to view the oil level.
(See page 21 for seat removal and instal-
lation procedures.) Recommended engine oil:

Pre-operation checks EJU31990Pre-operation check list
Before operating this watercraft, perform the checks in the following check list. See the accom-
panying text in this chapter for details on how to perform the checks.
WARNING
EWJ00410
If any item in the pre-operation check list is not working properly, have it inspected and
repaired before operating the watercraft, otherwise an accident could occur.
NOTE:
Pre-operation checks should be made each time the watercraft is used. These checks can be
completed in a short time. It is worth the time spent to ensure safety and reliability.

EJU32280Pre-operation check points EJU32300Engine compartment
Ventilate the engine compartment before
each use.
To ventilate the engine compartment, remove
the seat and front storage compartment. (See
“Seat” on page 21 and “Front storage com-
partment” on page 32 for more information.)
Leave the engine compartment open for a few
minutes to allow any fuel vapors to escape.
While the engine compartment is open, check
for loose electrical connections.
WARNING
EWJ00460
Failure to ventilate the engine compart-
ment could result in a fire or explosion. Do
not start the engine if there is a fuel leak or
a loose electrical connection.
EJU32350Hull and deck
Check the hull and deck for cracks and other
damage. If any damage is found, have a
Yamaha dealer repair the watercraft.
EJU32371Fuel and oil systems
Check the fuel system for leakage, cracks,
and malfunctions before each use. (See page
66 for check points and correct procedures.)
(1) Remove the fuel tank filler cap to release
any pressure that might have built up in
the fuel tank.(2) Remove the seat and front storage com-
partment. (See “Seat” on page 21 and
“Front storage compartment” on page 32
for more information.)
(3) Check the fuel and oil levels in the tanks
and replenish if necessary. (See page 36
for refueling procedures and page 36 for
oil tank filling procedures.)
(4) Install the fuel tank filler cap, seat, and
front storage compartment.
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.
EJU32440Bilge
Check the bilge for moisture and fuel residue.
This watercraft is equipped with a convention-
al jet vacuum bilge draining system and an
