EJU46380Drive control mode
The drive control mode is a function for set-
ting the maximum watercraft speed.
The maximum watercraft speed can be se-
lected from two settings.
Activating the drive control mode
Activation of the drive control mode can be

mum watercraft speed is saved. In addition,
the activation and settings of the drive control
mode can be locked to prevent others from
changing them. When the drive control mode is locked, a PIN
must be entered to operate the drive control
mode screen.
To select the maximum watercraft speed set-
ting:

EJU46390Cruise assist
The cruise assist is a function for maintaining
a desired engine speed within a fixed range
while operating the watercraft. Once the
cruise assist is activated, the set engine
speed can be increased or decreased. How-
ever, the adjustment is limited to a maximum
of five increments above or below the initial
cruise assist setting.
TIP:
The cruise assist can only be set between en-
gine speeds of approximately 4000 r/min and
approximately 7000 r/min.
Activating and deactivating the cruise as-
sist
Activation of the cruise assist can be con-
firmed by the cruise assist indicator on the
multifunction information center.
To activate the cruise assist:
(1) Operate the throttle lever until the de- sired engine speed is reached.
(2) When the engine speed reaches the de- sired cruise assist setting, push the “CRUISE/NO WAKE” switch. Once the
beeper sounds three times and the
cruise assist indicator is displayed, the
cruise assist is activated.
(3) When the cruise assist is activated, slow- ly squeeze the throttle lever to keep it
squeezed further than the position at
which the cruise assist was set.
TIP:
Check the multifunction information center to
make sure that the cruise assist is activated
before squeezing the throttle lever to the full
throttle position. If the cruise assist is not ac-
tivated, the engine will respond normally to
the throttle operation.
(4) Once the cruise assist is activated, pushthe upper side of the “SPEED ADJUST”
switch to increase the set engine speed
or the lower side of the “SPEED AD-
JUST” switch to decrease the set engine
speed. The engine speed can be

changed in the range of the cruise assist
levels –5 to +5.
TIP:
Because the cruise assist can only be set be-
tween engine speeds of approximately 4000
r/min and approximately 7000 r/min, the
cruise assist level cannot be adjusted to an
engine speed outside of this range.
To deactivate the cruise assist:
Relax your grip on the throttle lever past the
position at which the cruise assist was set.
The beeper sounds two times and the cruise
assist indicator disappears when the cruise
assist is deactivated.

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.

TIP:
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.

EJU43901Engine overheat warning
If the engine temperature rises significantly,
the engine overheat warning indicator, the
check engine warning indicator, and the
“WARNING” indicator light blink, and the
buzzer sounds intermittently. After 5 sec-
onds, the engine overheat warning indicator
and the “WARNING” indicator light stop
blinking and remain on, and the buzzer
sounds continuously. After 30 seconds, the
buzzer stops. While the engine overheat
warning is activated, 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
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.)
NOTICE: If you cannot locate and correct
the cause of the overheating, consult a
Yamaha dealer. Continuing to operate at higher speeds could result in severe en-
gine damage. [ECJ00042]

Check engine warning
If a sensor malfunction or a short circuit is de-
tected, the check engine warning indicator
and the “WARNING” indicator light blink, and
the buzzer sounds intermittently for 30 sec-
onds.
If the engine is stopped after the check en-
gine warning is activated, the tachometer
portion of the information display will show
