EJU37028Cruise assist
The cruise assist is a function for maintaining
a desired engine speed within a fixed range
while operating the watercraft.
TIP:
The cruise assist can only be set between
engine speeds of approximately 3000
r/min and approximately 7000 r/min.
The cruise assist cannot be activated in the
Low RPM Mode. (See page 32 for Low
RPM Mode activation procedures.)
Activating and deactivating the cruise as-
sist
Activation of the cruise assist will be con-
firmed by the number of beeps when the
“SET” switch, cruise assist up switch, or
cruise assist down switch is pushed, and by
the digital speedometer display of the multi-
function information center. (See page 37 for
information on the multifunction information
center.)
TIP:
The beeps and the blinking digital speedom-
eter display also indicate the activation of the
no-wake mode. (See page 33 for information
on the no-wake mode.)
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
“SET” switch. Once the beeper soundsthree times quickly and the digital speed-
ometer display starts blinking, the cruise
assist is activated. When the cruise as-
sist is activated, slowly squeeze the
throttle lever to keep it squeezed further
than the position at which the cruise as-
sist was set; releasing the throttle lever
will deactivate the cruise assist.
TIP:
The digital speedometer display blinks con-
tinually while the cruise assist is activated.
Make sure that the beeper has sounded and
the digital speedometer display is blinking
before squeezing the throttle lever to the full
throttle position. If the speedometer display is
not blinking, the cruise assist is not activated

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:
The “UNLOCK” indicator light also comes on
as part of the initial operation.
The “UNLOCK” 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 totheir state before the center turned off, and
then the center starts to operate normally.
EJU35027Information display
The information display shows watercraft op-
erating conditions.
EJU43831Speedometer
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”.

Yamaha factory.
To switch the speedometer display units:
Start the engine, stop the engine, and then
push the engine stop switch 3 times, pushing
the switch for 0.4 seconds or more each time,
before the multifunction information center
turns off. The speedometer display units

If the fuel level warning is activated, refill the
fuel tank as soon as possible. (See page 49
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 51 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 overheatwarning 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 92 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.

EJU43731
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.

Draining the bilge water
NOTICE
ECJ01302
Do not run the engine at full throttle when
bilge water remains in the engine com-
partment. The bilge water can splash into
the engine, which can result in severe
damage.
EJU44260Draining the bilge water on land
To drain the bilge water on land:
(1) Loosen the stern drain plugs and remove
them.
(2) Raise the bow of the watercraft, such as
by placing the watercraft on a slope, to
drain the bilge water from the engine
compartment.
(3) After the bilge water has drained from the
stern drain plug holes, wipe up any re-
maining moisture in the engine compart-
ment with a dry cloth.
(4) Check that the stern drain plugs and O-
rings on the plugs are not damaged and
that there is no foreign material on the
threads or O-rings on the plugs.
NOTICE: Before installing the stern
drain plugs, clean the drain plug
threads and the O-rings on the plugs
to remove any foreign materials, such
as dirt or sand. Otherwise, the sterndrain plugs could be damaged, allow-
ing water to enter the engine compart-
ment. Check the O-rings on the stern
drain plugs and make sure that the
plugs are tightened securely before
launching the watercraft. Otherwise,
water may flood the engine compart-
ment and cause the watercraft to sub-
merge.
[ECJ00363]
(5) Securely install the stern drain plugs by
tightening them until they stop.
EJU40535Draining the bilge water on water
A small quantity of bilge water will remain in
the engine compartment even after the bilge
water is drained on water. To completely
drain the bilge water, remove the watercraft
from the water and drain the bilge water on
land.
Jet vacuum bilge draining system
While the watercraft is operating, bilge water
in the engine compartment is drawn in by the
vacuum that is generated in the jet pump and
discharged from the watercraft through the
jet thrust nozzle.
To drain the bilge water on water:
Operate the watercraft as straight as possible
and above planing speed for at least 2 minu-
tes. NOTICE: Do not run the engine at full
throttle for at least 1 minute after the en-
gine has been restarted. Bilge water in the
