Multifunction information center (VX-C / VX)
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.
Multifunction information center standby
state
If the multifunction information center does
not receive any operation input within 30 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.
EJU35027Information display
The information display shows watercraft op-
erating conditions.
EJU46430Speedometer
The speedometer shows the watercraft
speed.
By switching the display units, the speed can
be shown in kilometers per hour “km/h” or
miles per hour “MPH”.
TIP:
“MPH” is selected as the display unit at the
Yamaha factory.

craft.
EJU37272Fuel 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
depending on the operating conditions. Use
this function as a reference only.
EJU44711Fuel 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 fuel level segment, the fuel level warning
indicator, and the “WARNING” indicator lightblink, 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 62
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 64 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.

Use only 4-stroke engine oil. Usage of 2-
stroke engine oil could result in severe en-

Why Yamalube
YAMALUBE oil is a Genuine YAMAHA Part
born of the engineers’ passion and belief that
engine oil is an important liquid engine com-
ponent. We form teams of specialists in the
fields of mechanical engineering, chemistry,
electronics and track testing, and have them
develop the engine together with the oil it will
use. Yamalube oils take full advantage of the
base oil’s qualities and blend in the ideal bal-
ance of additives to make sure the final oil
clears our performance standards. Thus,
Yamalube mineral, semisynthetic and syn- thetic oils have their own distinct characters
and value. Yamaha’s experience gained over
many years of research and development
into oil since the 1960’s helps make
Yamalube the best choice for your Yamaha engine. Checking the engine oil level
EWJ00341
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.
ECJ00392
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 pas-
sages. (See “Flushing the cooling water
passages” on page 92 for information on
supplying water.)
When checking the engine oil level on wa-
ter, moor the watercraft so that it will not
drift away.
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 79 for information on
starting the engine.)
(3) Run the engine at idling speed for 6 min- utes 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 seats. (See page 54 for seat removal and installation procedures.)
Recommended engine oil:
YAMALUBE 4W or 4-stroke motor oil
Recommended engine oil type: SAE 10W-30, 10W-40, 20W-40,
20W-50
Recommended engine oil grade: API SG, SH, SJ, SL

Engine break-inECJ00432
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 64for information on checking the engine
oil level.)
(2) Launch the watercraft and start the en- gine. (See page 79 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.

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 64 for information on checking the

Internal: Drink large quantities of water or
milk. Follow with milk of magnesia, beaten
egg, or vegetable oil. Call a physician im-
mediately.
Eyes: Flush with water for 15 minutes and
get prompt medical attention.
Batteries produce explosive gases. Keep
sparks, flames, cigarettes, etc., well away.
If using or charging the battery in an en-
closed space, make sure that it is well
ventilated. Always shield your eyes when
working near batteries.
Keep out of the reach of children.
To remove the battery:
(1) Disconnect the negative (–) battery lead.
(2) Disconnect the positive (+) battery lead.
(3) Unhook the battery bands, and then re-move the battery from the watercraft.
Checking the battery
Make sure that the battery case is not dam-
aged.
Make sure that the battery terminals are
not corroded or damaged.
Checking the battery voltage and charging
the battery
It is recommended to have a Yamaha dealer
check the battery voltage and charge the bat-
tery. Have a Yamaha dealer charge the bat- tery as soon as possible if it seems to have
discharged. Keep in mind that the battery
tends to discharge more quickly if the vehicle
is equipped with optional electrical accesso-
ries.
NOTICE: To charge a VRLA (Valve
Regulated Lead Acid) battery, a special
(constant-voltage) battery charger is re-
quired. Using a conventional battery char-
ger will damage the battery.
[ECJ02810]
Checking the battery bands
Make sure that the battery bands are not
damaged.
To store the battery:
(1) Clean the battery case using fresh water.
(2) If the battery terminals are dirty or cor- roded, clean them using a wire brush.
(3) Apply water-resistant grease to the bat- tery terminals.
