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.

While the engine is stopped, the battery volt-
age and the total engine hours are displayed
alternately.
EJU46200Shift indicator (VX)
This indicator shows the reverse gate shift
positions: “F” (forward), “N” (neutral), and “R”
(reverse). (See page 30 for shifting proce-
dures.)
EJU44700Hour 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

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.

If the engine overheat warning is activated,
immediately reduce the engine speed, return
to shore, and then make sure that water is
being 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 107 for information on the jet intake.)
