EJU35024Information display
The information display shows watercraft op-
erating conditions.
EJU37264Hour meter/voltmeter
The hour meter/voltmeter has both an hour
meter function and a voltmeter function. By
switching the meter, it can be used as either
an hour meter or a voltmeter.
TIP:
The hour meter is selected at the Yamaha
factory.Hour meter
The hour meter shows the total number of
hours that the engine has been running since
the watercraft was new.
TIP:
The elapsed time will be kept even if the bat-
tery terminals have been disconnected.
To switch to the hour meter from the voltme-
ter:
Push the “Hour Volt” button for at least 1 sec-
ond. The display switches to the hour meter
from the voltmeter.
Voltmeter
The voltmeter shows the battery voltage.
When the battery voltage is normal, the volt-
meter displays approximately 12 volts.
If the battery voltage has dropped significant-
ly, “LO” is displayed on the voltmeter. If the
battery voltage has risen significantly, “HI” is
displayed. If “LO” or “HI” is displayed, immedi-
ately return to shore and have a Yamaha
dealer service the watercraft.

To switch to the voltmeter from the hour
meter:
Push the “Hour Volt” button for at least 1 sec-
ond. The display switches to the voltmeter
from the hour meter.
EJU37271Fuel level meter
The fuel level meter shows the amount of fuel
remaining in the fuel tank. The amount of re-
maining fuel is shown using four display seg-
ments, which disappear one at a time as the
fuel level decreases.
TIP:
The accuracy of the fuel level meter varies de-
pending on the operating conditions. Use this
function as a reference only.
EJU37282Fuel level warning
If the fuel remaining in the fuel tank drops to
about 18 L (4.8 US gal, 4.0 Imp. gal), the
“WARNING” indicator light, the fuel indicator,
and the lowest fuel level segment blink, and
the buzzer sounds intermittently.
If the fuel level warning is activated, refill the
fuel tank as soon as possible. (See page 48
for information on filling the fuel tank.)
After the fuel tank is refilled, the warning sig-
nals will be cleared when the engine is restart-
ed.
TIP:
Push the “Hour Volt” button to stop the buzz-
er.
EJU37292Oil pressure warning
If the oil pressure drops significantly, the
“WARNING” indicator light and the oil pres-
sure warning indicator blink, and the buzzer

sounds intermittently. 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 50 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.
TIP:
Push the “Hour Volt” button to stop the buzz-
er.
EJU37301Engine overheat warning
If the engine temperature rises significantly,
the “WARNING” indicator light and the engine
overheat warning indicator blink, and the
buzzer sounds intermittently. Then, the
“WARNING” indicator light and the engine
overheat warning indicator stop blinking and
remain on, and the buzzer sounds continu-
ously. After the light and indicator start to blinkand the buzzer sounds, 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 be-
ing discharged from the port (left) cooling wa-
ter pilot outlets while the engine is running. If
there is no discharge of water, stop the en-
gine, and then check the jet intake for clog-
ging. (See page 91 for information on the jet
intake.) NOTICE: If you cannot locate and
correct the cause of the overheating, con-
sult a Yamaha dealer. Continuing to oper-
ate at higher speeds could result in severe
engine damage.

TIP:
Push the “Hour Volt” button to stop the buzz-
er.

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.
[ECJ00122]
(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.
EJU33735Cleaning the watercraft
(1) Remove the seats. (See page 40 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.
[ECJ00571]
(3) Drain the water from the engine compart-
ment. (See page 51 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.
EJU33686Battery 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.
WARNING
EWJ00791
Battery electrolyte is poisonous and dan-
gerous, causing severe burns, etc. Elec-
trolyte contains sulfuric acid. Avoid
contact with skin, eyes, or clothing.
Antidotes
External: Flush with water.
Internal: Drink large quantities of water or
milk. Follow with milk of magnesia, beaten
egg, or vegetable oil. Call a physician im-
mediately.
