EJU43981Cruise assist (VX Deluxe /
VX Cruiser / VX Limited)
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 4000
r/min and approximately 7000 r/min.
The cruise assist cannot be activated in the
Low RPM Mode. (See page 33 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 38 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 34 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 sounds
three 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

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 ba-
lance 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
WARNING
EWJ00341

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
