EJU35122Oil pressure warning indicator
If the oil pressure does not rise to specifica-
tion, the “WARNING” indicator light and the oil
pressure warning indicator begin to blink, and
the buzzer sounds intermittently. At the same
time, the engine speed is limited to help pre-
vent damage.
If this occurs, reduce the engine speed, return
to shore, and then check the engine oil level.
(See page 53 for engine oil level checking
procedures.) If the oil level is low, add enough
engine oil to raise it to the proper level. If the
oil level is sufficient, have a Yamaha dealer
check the watercraft.
NOTE:
Press any button on the multifunction informa-
tion center to stop the buzzer.
EJU36401Engine overheat warning indicator
This model is equipped with an engine over-
heat warning system.
If the engine starts to overheat, the engine
overheat warning system will be activated
and, in some cases, the warning system will
cut the ignition to the engine.
If the “WARNING” indicator light and the en-
gine overheat warning indicator begin to blink,
and the buzzer sounds intermittently, immedi-ately reduce the engine speed and return to
shore.
If the “WARNING” indicator light and the en-
gine overheat warning indicator come on, and
the buzzer sounds continuously, the warning
system will cut the ignition. The engine cannot
be started until it cools down, so it may be
necessary to have the watercraft towed back
to the shore. (See “Towing the watercraft” on
page 97 for towing procedures.)
After the engine cools down, start the engine,
and then check for water discharge at the port
(left) cooling water pilot outlet while the engine
is running. If there is no discharge of water,
shut the engine off, and then check the intake
grate and impeller for clogging.
WARNING

Fuel and oil
This watercraft is equipped with a 4-stroke en-
gine. Conventional 2-stroke engine oil cannot
be used.
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.
EJU36330Gasoline
WARNING
EWJ00280
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 reaches approxi-
mately 50 mm (2 in) from the top of the
fuel tank. Fuel expands as it warms up
and could overflow if the fuel tank has
been overfilled. If temporarily leaving
the watercraft with a full fuel tank, do not
leave it in direct sunlight. Leave it in a
well-ventilated area with the watercraft
in a horizontal position.

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)

EJU32280Pre-operation check points EJU32330Engine compartment
Ventilate the engine compartment before
each use.
To ventilate the engine compartment, remove
the seats. (See page 24 for seat removal and
installation procedures.) 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.
EJU32380Fuel level
Check the fuel system for leakage, cracks,
and malfunctions before each use. (See page
83 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 seats. (See page 24 for seat
removal and installation procedures.)
(3) Check the fuel level in the fuel tank and
replenish if necessary. (See page 50 for
filling procedures.)
(4) Install the fuel tank filler cap and the
seats.
EJU32411Engine oil level
Check the engine oil level before each use.
CAUTION:
ECJ00390

When checking the engine oil level on
water, be careful of other watercraft,
boats, swimmers, and obstacles. The
water current and wind can cause the
watercraft to move and lead to a colli-
sion.

When checking the engine oil level on
land, supply water to the cooling water
passages. (See page 76 for procedures
on supplying water.)

Make sure that the engine has enough
oil, but do not overfill it. If there is too lit-
tle oil, the engine can be damaged. If
there is too much oil, the air filter can be-
come saturated with oil, permanently
damaging the filter and reducing engine
performance. Follow the checking pro-
cedure carefully.

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.
(2) Run the engine at trolling speed for 6 min-
utes or more, and then stop the engine.

NOTE:
If the ambient temperature is 20 °C (68 °F) or
less, warm up the engine for an additional 5
minutes.
(3) Remove the seats. (See page 24 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 level mark and maximum level
mark 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.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.
EJU32450Bilge
Check the bilge for moisture and fuel residue.
This watercraft is equipped with a convention-
al jet vacuum bilge draining system and an
electric bilge draining system. The electric
bilge draining system is operated when the
engine is running. When excess water reach-
es the water inlet of the electric bilge pump,

the water is discharged from the electric bilge
pilot outlet at the stern.
A small quantity of water will remain in the
bilge and should be drained manually. To
drain any residual water, beach the watercraft
and perform the following procedure.
CAUTION:
ECJ00350
If starting the engine after the watercraft
has capsized, do not operate the engine at
full throttle when water is being dis-
charged from the electric bilge pilot outlet
at the stern. Excessive water in the bilge
can splash into the engine, which can re-
sult in severe damage.
To drain water from the bilge:
(1) Remove the stern drain plugs.
(2) Raise the bow of the watercraft until the
water drains.
(3) After the water has drained, wipe the
bilge with dry rags to make sure that it is
thoroughly dry.
(4) Install the stern drain plugs.
CAUTION:
ECJ00360

Before installing the stern drain plugs,
clean the drain plug threads to remove
any foreign materials, such as dirt or
sand. Otherwise, the stern drain plugscould be damaged, allowing water to en-
ter the engine compartment.

Make sure that the stern drain plugs are
tightened securely before launching the
watercraft. Otherwise, water may flood
the engine compartment and cause the
watercraft to submerge.
