EJU44710Fuel level warning
If the fuel remaining in the fuel tank drops to
about 8 L (2.1 US gal, 1.8 Imp.gal), the lowest
fuel level segment, the fuel level warning indi-
cator, and the “WARNING” indicator light
blink, 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 44
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 46 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.
EJU43901Engine overheat warning
If the engine temperature rises significantly,
the engine overheat warning indicator, the
check engine warning indicator, and the
“WARNING” indicator light blink, and the
buzzer sounds intermittently. After 5 sec-
onds, the engine overheat warning indicator
and the “WARNING” indicator light stop
blinking and remain on, and the buzzer
sounds continuously. After 30 seconds, the
buzzer stops. While the engine overheat
warning is activated, 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
being discharged from the cooling water pilot
outlet while the engine is running. If there is
no discharge of water, stop the engine, and
then check the jet intake for clogging. (See
page 90 for information on the jet intake.)
NOTICE: If you cannot locate and correct
the cause of the overheating, consult a
Yamaha dealer. Continuing to operate at

Operation and handling requirements
47
To check the engine oil level:
(1) With the engine stopped, place the wa-
tercraft in a precisely level position on
land or launch the watercraft.
(2) Look in all directions, and then start the
engine. (See page 62 for information on
starting the engine.)
(3) Run the engine at idling speed for 6 mi-
nutes or more. Run the engine an addi-
tional 5 minutes if the ambient
temperature is 20 °C (68 °F) or less.
(4) Stop the engine.
(5) Remove the seat and seat storage com-
partment. (See page 38 for seat removal
and installation procedures and page 42
for information on the seat storage com-
partment.)
(6) Loosen the oil tank filler cap and remove
it, and then wipe the attached dipstick
clean.
(7) Screw the oil tank filler cap into the filler
hole until it stops. Remove the oil tank
filler cap again and make sure that theengine oil level is between the minimum
and maximum level marks.
(8) 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, slowly
add engine oil.
(9) Repeat steps 6–8 until the engine oil is at
the proper level.
(10) Securely install the oil tank filler cap and
turn it until it stops.
(11) Securely install the seat storage com-
partment and seat in their original posi-
tions.

Draining the bilge water
NOTICE
ECJ01302
Do not run the engine at full throttle when
bilge water remains in the engine com-
partment. The bilge water can splash into
the engine, which can result in severe
damage.
EJU44260Draining the bilge water on land
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-
maining moisture in the engine compart-
ment with a dry cloth.
(4) Check that the stern drain plugs and O-
rings on the plugs are not damaged and
that there is no foreign material on the
threads or O-rings on the plugs.
NOTICE: Before installing the stern
drain plugs, clean the drain plug
threads and the O-rings on the plugs
to remove any foreign materials, such
as dirt or sand. Otherwise, the sterndrain plugs could be damaged, allow-
ing water to enter the engine compart-
ment. Check the O-rings on the stern
drain plugs and make sure that the
plugs are tightened securely before
launching the watercraft. Otherwise,
water may flood the engine compart-
ment and cause the watercraft to sub-
merge.
[ECJ00363]
(5) Securely install the stern drain plugs by
tightening them until they stop.
EJU40535Draining the bilge water on water
A small quantity of bilge water will remain in
the engine compartment even after the bilge
water is drained on water. To completely
drain the bilge water, remove the watercraft
from the water and drain the bilge water on
land.
Jet vacuum bilge draining system
While the watercraft is operating, bilge water
in the engine compartment is drawn in by the
vacuum that is generated in the jet pump and
discharged from the watercraft through the
jet thrust nozzle.
To drain the bilge water on water:
Operate the watercraft as straight as possible
and above planing speed for at least 2 minu-
tes. NOTICE: Do not run the engine at full
throttle for at least 1 minute after the en-
gine has been restarted. Bilge water in the
