TIP:
The accuracy of the fuel level meter varies
depending on the operating conditions. Use
this function as a reference only.
EJU44080Fuel 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 two fuel level segments, the fuel indicator,
and the “WARNING” indicator light blink, and
the buzzer sounds intermittently for 30 sec-
onds.
If the fuel level warning is activated, refill the
fuel tank as soon as possible. (See page 50
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 52 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

ter flows out continually from the jet
thrust nozzle.
(7) Run the engine at idling speed for about
3 minutes watching the engine condition.
If the engine stops while flushing, turn
the water supply off immediately and
perform the procedure again from step 6.
NOTICE: Do not supply water to the
cooling water passages when the en-
gine is not running. The water could
flow back through the muffler into the
engine, causing severe engine dam-
age.
[ECJ00123]
(8) Turn the water supply off.
(9) Discharge the remaining water out of the
cooling water passages by alternately
squeezing and releasing the throttle lever
quickly for 10 to 15 seconds.
(10) Stop the engine.
(11) Remove the garden hose adapter, and
then securely install the flushing hose
connector cap by tightening it until it
stops.
(12) Securely install the watertight storage
compartment and seats in their original
positions.
EJU33736Cleaning the watercraft
(1) Remove the seats. (See page 43 for seat
removal and installation procedures.)
(2) Rinse the engine and engine compart-
ment with a small amount of water.NOTICE: Do not use high-pressure
water when rinsing the engine or en-
gine compartment as severe engine
damage could result.
[ECJ00572]
(3) Drain the water from the engine com-
partment. (See page 54 for information
on draining the bilge water.)
(4) Wipe the engine and engine compart-
ment with a dry cloth.
(5) Wash down the hull, deck, and jet pump
with fresh water.
(6) Wipe the hull, deck, and jet pump with a
dry cloth.
(7) Wipe all vinyl and rubber components,
such as the seats and engine compart-
ment seals, with a vinyl protectant.
(8) To minimize corrosion, spray metallic
parts of the hull, deck, and engine with a
rust inhibitor.
(9) Allow the engine compartment to air dry
completely before installing the seats.
(10) Securely install the seats in their original
positions.
EJU33687Battery care
If the watercraft will not be used for more than
a month, remove the battery from the water-
craft, check it, and then store it in a cool, dry
place.
