Multifunction information
center
The multifunction information center displays
various watercraft information.
Multifunction information center initial op-
eration
When the multifunction information center is
activated, all of the display segments come
on. After 2 seconds, the warning indicators in
the information display go off, and then the
center starts to operate normally.
If only the multifunction information center is
activated, the “WARNING” indicator light
blinks once.
TIP:
VX Deluxe / VX Cruiser: The “SECURITY” in-
dicator light also comes on as part of the initial
operation.
The “SECURITY” indicator light will go off
when the engine is started.
Multifunction information center standby
state
If the multifunction information center does
not receive any operation input within 25 sec-onds after the engine stops, the center will
turn off and enter a standby state. When the
engine is started again, the displays return to
their state before the center turned off, and
then the center starts to operate normally.
EJU35024Information display
The information display shows watercraft op-
erating conditions.
EJU31503Speedometer
The speedometer shows the watercraft speed
against water.
By switching the display units, the speed can
be shown in kilometers per hour “km/h” or
miles per hour “mph”.

cator light blink, and the buzzer sounds inter-
mittently.
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 restart-
ed.
TIP:
Push the select button on the multifunction in-
formation center to stop the buzzer.
EJU31626Oil pressure warning
If the oil pressure drops significantly, the oil
pressure warning indicator and the “WARN-
ING” indicator light 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 45 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.
TIP:
Push the select button on the multifunction in-
formation center to stop the buzzer.
EJU31609Engine overheat warning
If the engine temperature rises significantly,
the engine overheat warning indicator and the
“WARNING” indicator light blink, and the
buzzer sounds intermittently. Then, the en-
gine overheat warning indicator and the
“WARNING” indicator light stop blinking and
remain on, and the buzzer sounds continu-
ously. At the same time, 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 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
84 for information on the jet intake.) NOTICE:
If you cannot locate and correct the cause
of the overheating, consult a Yamaha deal-
er. Continuing to operate at higher speeds

(6) Stop filling when the fuel level reaches
approximately 50 mm (2 in) from the top
of the fuel tank. Do not overfill the fuel
tank. Because fuel expands when it heats
up, heat from the engine or the sun can
cause fuel to spill out of the fuel tank. Do
not leave the watercraft with a full tank in
direct sunlight.
(7) Wipe up any spilled fuel immediately with
a dry cloth.
(8) Securely install the fuel filler cap by tight-
ening it until it clicks.
(9) Securely install the seat in its original po-
sition.

Engine oil requirements EJU41542Engine oil
NOTICE
ECJ00281
Use only 4-stroke engine oil. Usage of 2-
stroke engine oil could result in severe en-
gine damage.
Checking the engine oil level
WARNING
EWJ00340
Engine oil is extremely hot immediately af-
ter the engine is turned off. Coming in con-
tact with or getting any engine oil on your
clothes could result in burns.
NOTICE
ECJ00391
●Do not run the engine with too much or
not enough oil in the oil tank, otherwise
the engine could be damaged.
●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.
TIP:
●When checking the engine oil level on land,
the engine must be running while water is
being supplied to the cooling water passag-
es. (See “Flushing the cooling water pas-
seges” on page 71 for information on
supplying water.)
●When checking the engine oil level on wa-
ter, moor the watercraft so that it will not drift
away. Fuel tank capacity:
60 L (15.9 US gal, 13.2 Imp.gal)
1Approximately 50 mm (2 in) from top of the

Operation and handling requirements

To check the engine oil level:
(1) With the engine stopped, place the water-
craft in a precisely level position on land
or launch the watercraft.
(2) Look in all directions, and then start the
engine. (See page 60 for information on
starting the engine.)
(3) Run the engine at idling speed for 6 min-
utes or more. Run the engine an addition-
al 5 minutes if the ambient temperature is
20 °C (68 °F) or less.
(4) Stop the engine.
(5) Remove the seat. (See page 38 for seat
removal and installation procedures.)
(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 fill-
er cap again and make sure that the en-gine 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 in its original po-
sition.

Engine break-in
NOTICE
ECJ00431
Failure to perform the engine break-in
could result in reduced engine life or even
severe engine damage.
The engine break-in is essential to allow the
various components of the engine to wear
and polish themselves to the correct operat-
ing clearances. This ensures proper perfor-
mance and promotes longer component life.
To perform the engine break-in:
(1) Check the engine oil level. (See page 45
for information on checking the engine oil
level.)
(2) Launch the watercraft and start the en-
gine. (See page 60 for information on
starting the engine.)
(3) For the first 5 minutes, operate with the
engine at idling speed.
(4) For the next 30 minutes, operate with the
engine speed below 5000 r/min.
(5) For the next 1 hour, operate with the en-
gine speed below 6500 r/min.
After the engine break-in is complete, the wa-
tercraft can be operated normally.
