Instrument operation
32
To switch the speedometer display
units:
Start the engine, stop the engine, and then
remove and insert the clip 3 times before the
multifunction information center turns off.
The speedometer display units change.
To switch the speedometer display units
again, repeat this procedure.
EJU44650Tachometer
The tachometer shows the engine speed.
TIP
While the engine is stopped, the battery volt-
age and the total engine hours are displayed
alternately.
EJU43891Shift indicator
This indicator shows the reverse gate shift
positions: “F” (forward), “N” (neutral), and “R”
(reverse). (See page 27 for shifting proce-
dures.)
EJU47181Trim indicator
This indicator shows the trim angle of the jet
thrust nozzle. When the neutral position of
the jet thrust nozzle is selected, the trim indi-
cator shows the segment next to the trim
icon. Increasing the trim angle will show the

upper segment of the trim indicator, and de-
creasing the trim angle will show the lower
segment of the trim indicator. (See page 29
for trim angle selection procedures.)
EJU44701Hour meter and voltmeter
The hour meter and voltmeter are displayed
in the tachometer portion of the information
display while the engine is stopped.
The hour meter and voltmeter are displayed
alternately at 3-second intervals.
TIP
If the engine is stopped after the check en-
gine warning is activated, the hour meter and
error code will be displayed alternately at 3-
second intervals.
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.
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, and all
other display segments of the information
display turn off. If the battery voltage has ris-
en significantly, “HI” is displayed. If “Lo” or
“HI” is displayed, immediately return to shore
and have a Yamaha dealer service the water-
craft.

Pre-operation checks
51
EJU40182Engine unit check
Check the exterior of the engine unit for dam-
age or other problem.
EJU41561Engine oil level check
Make sure that the engine oil level is between
the minimum and maximum level marks on
the dipstick attached to the oil tank filler cap.
(See page 43 for information on checking the
engine oil level.)
EJU32456Bilge water check
Make sure that no bilge water has collected in
the engine compartment. If bilge water has
collected in the engine compartment, drain it.
(See page 45 for information on draining the
bilge water.)
EJU32488Battery checks
Make sure that the battery terminals are not
damaged and that the battery leads are con-
nected properly. WARNING! Never operate
the watercraft if the battery does not have
sufficient power to start the engine or if it

eral times to make sure that operation is
smooth and unrestricted throughout the
whole range, and that the free play is not ex-
cessive.
Turn the handlebars as far as possible to the
right and left to make sure that the jet thrust
nozzle moves as the handlebars are turned,
and that there is no difference between the
right and left fully turned positions of the jet
thrust nozzle.
EJU43213RiDE lever checks
Operate the RiDE lever several times to make
sure that operation is smooth throughout the
whole range. Also, make sure that the RiDE
lever returns automatically to its fully closed
position when released.

Operate the throttle lever several times to
make sure that operation is smooth through-
out the whole range. Also, make sure that the
throttle lever returns automatically to its fully
closed (idle) position when released.

Care and storage
70
(7) Run the engine at idling speed for about3 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 seat storage com- partment and seat in their original posi-
tions.
EJU44770Cleaning the watercraft
(1) Remove the seat and fire extinguisherholder. (See page 36 for seat removal
and installation procedures and page 40
for information on the fire extinguisher
holder.) (2) If the watercraft will be stored for a week
or more, rustproof the internal engine
components to help prevent corrosion.
(See page 73 for information on rust-
proofing the internal engine compo-
nents.)
(3) 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]
(4) Drain the water from the engine com- partment. (See page 45 for information
on draining the bilge water.)
(5) Wipe the engine and engine compart- ment with a dry cloth.
(6) Wash down the hull, deck, and jet pump with fresh water.
(7) Wipe the hull, deck, and jet pump with a dry cloth.
(8) Wipe all vinyl and rubber components, such as the seat and engine compart-
ment seals, with a vinyl protectant.
(9) To minimize corrosion, spray metallic parts of the hull, deck, and engine with a
rust inhibitor.
(10) Allow the engine compartment to air dry completely before installing the seat.
(11) Securely install the fire extinguisher hold- er and seat in their original positions.
EJU3368DBattery 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.
