Cruising limitations
Scan constantly for people, objects, and
other watercraft. Be alert for conditions
that limit your visibility or block your vision
of others.
Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft.
Do not follow directly behind watercraft or
other boats.
Do not go near others to spray or splash
them with water, go too close to other
boats, or go too fast for the traffic condi-
tions.
VX-C: Take early action to avoid collisions.
Remember, watercraft and other boats do
not have brakes.
VX-C: Avoid sharp turns or other maneu-
vers that make it hard for others to avoid
you or understand where you are going.
VX / VX DELUXE / VX CRUISER / VX
LIMITED: Take early action to avoid colli- sions. Remember, watercraft and other
boats do not have brakes. In addition, the
Reverse with Intuitive Deceleration Elec-
tronics (RiDE) system is not a braking de-
vice for avoiding dangerous situations. The
RiDE system is an electronic system for
controlling the engine speed and reverse
gate, which is located near the jet thrust
nozzle. The RiDE lever located at the left handlebar grip can be used to change the
direction of the jet thrust so that the water-
craft moves in reverse or is in neutral. The
RiDE system assists the operator when
slowing down and during slow-speed ma-
neuvering, such as launching, beaching,
and docking.
VX / VX DELUXE / VX CRUISER / VX
LIMITED: Avoid sharp turns, slowing down rapidly by squeezing the RiDE lever force-
fully, and other maneuvers that make it
hard for others to avoid you or understand
where you are going.
Avoid areas with submerged objects or
shallow water.
Do not release the throttle lever when trying
to steer away from objects—as with other
powerboats, you need throttle to steer. Al-
ways check throttle and steering controls
before starting the watercraft.
Ride within your limits and avoid aggres-
sive maneuvers to reduce the risk of loss of
control, ejection, and collision.
This is a high performance boat—not a toy.
Avoid aggressive operation, sharp turns,
and unexpected acceleration that can cau-
se you to be thrown off. Do not jump waves
or wakes—jumping can cause injuries such
as back or spinal injuries (paralysis), facial
injuries, and broken legs, ankles, and other
bones. Improper operation can result in se-
vere injury or death.
Do not operate the watercraft in rough wa-
ter, bad weather, or when visibility is poor;
this may lead to an accident causing injury
or death. Be alert to the possibility of ad-
verse weather. Take note of weather fore-
casts and the prevailing weather
conditions before setting out on your wa-
tercraft.

in certain kinds of accidents and that it
could injure you in others.
A helmet is designed to provide some head
protection. Although helmets cannot pro-
tect against all foreseeable impacts, a hel-
met might reduce your injuries in a collision
with a boat or other obstacle.
A helmet may have potential safety haz-
ards, as well. Falling into the water could
risk the chance of the helmet catching wa-
ter, commonly known as “bucketing”, and
the resulting strain on your neck could cau-
se choking, severe and permanent neck in-
juries, or death. A helmet could also
increase the risk of an accident if it reduces
your vision or hearing, or if it distracts you
or increases your fatigue.
How should you decide if a helmet’s poten-
tial safety benefits outweigh its potential
risks for you? Consider your particular rid-
ing conditions. Consider factors such as
your riding environment and your riding
style and ability. Also consider the likeli-
hood of traffic congestion, and the water
surface conditions.
If you decide to wear a helmet based upon
your riding circumstances, choose one
carefully. Look for a helmet designed for
personal watercraft use, if possible. If you
will be engaging in closed-course competi-
tion, follow the helmet requirements of the
sanctioning organization.
Never operate the watercraft after consum-
ing alcohol or taking other drugs.
For reasons of safety and proper care of
the watercraft, always perform the pre-op-
eration checks listed on page 68 before op-
erating the watercraft.
The operator should grip the handlebars
firmly with both hands and the passengers
should hold on firmly, either to the person in front of them or to the handgrip provid-
ed.
The operator and passengers should al-
ways keep their feet on the floor of the foot-
well when the watercraft is in motion.
Lifting your feet increases the chances of
losing your balance,
or hitting objects out-
side the watercraft with your feet. Do not
give a ride to children if their feet cannot
reach the floor of the footwell.
Never allow a passenger to ride in front of
the operator.
Always consult your doctor on whether it is
safe for you to ride this watercraft if you are
pregnant or in poor health.
Do not attempt to modify this watercraft.
Modifications to your watercraft may re-
duce safety and reliability, and render the
watercraft unsafe or illegal for use.
Attach the engine shut-off cord (lanyard) to
y o u r l ef t w r is t an d k ee p i t fr e e f r o m t h e h an -
dlebars so that the engine stops if you, the
operator, fall off. After riding, remove the
engine shut-off cord (lanyard) from the wa-
tercraft to avoid accidental starting or un-
authorized use by children or others.

VX / VX DELUXE / VX CRUISER / VX
LIMITED: To avoid rear-end collisions while operating the watercraft, check behind you
before using the RiDE lever to slow down
or stop the watercraft. Make sure that there
are no obstacles or people behind you be-
fore shifting into reverse.
Keep away from the intake grate while the
engine is on. Items such as long hair, loose
clothing, or PFD straps can become entan-
gled in moving parts, resulting in severe in-
jury or drowning.
Never insert any object into the jet thrust
nozzle while the engine is running. Severe
injury or death could result from coming in contact with the rotating parts of the jet
pump.
Stop the engine and remove the clip from
the engine shut-off switch before removing
any debris or weeds, which may have col-
lected around the jet intake.1

EJU43342RiDE lever (VX / VX DELUXE /
VX CRUISER / VX LIMITED)
When the RiDE lever is squeezed, the reverse
gate lowers and the watercraft starts moving
in reverse. If the watercraft is moving forward,
the watercraft gradually slows down until it
stops, and then the watercraft starts moving
in reverse.
When the RiDE lever is released, it automati-
cally returns to its fully closed (idle) position
and the reverse gate moves to the neutral po-
sition.
EJU31262Steering system
By turning the handlebars in the direction you
wish to travel, the angle of the jet thrust noz-
zle is changed, and the direction of the water-
craft is changed accordingly.Since the strength of the jet thrust determines
the speed and degree of a turn, throttle must
always be applied when attempting a turn,
except at trolling speed.
This model is equipped with the Yamaha En-
gine Management System (YEMS) that in-
cludes an off-throttle steering (OTS) system.
It will activate at planing speeds should you
attempt to steer the watercraft after releasing
the throttle lever. The OTS system assists in
turning by continuing to supply some thrust
while the watercraft is decelerating, but you
can turn more sharply if you apply throttle
while turning the handlebars. The OTS sys-
tem does not function below planing speeds
or when the engine is off. Once the engine
slows down, the watercraft will no longer turn
in response to handlebar input until you apply
throttle again or you reach trolling speed.
EJU35975Cooling water pilot outlet
When the engine is running, some of the
cooling water that is circulated in the engine
is discharged from the cooling water pilot
outlet.
There is a cooling water pilot outlet on the
port (left) side of the watercraft. To check for
proper operation of the cooling system, make
sure that water is being discharged from the
cooling water pilot outlet. If water is not being
discharged from the outlet, stop the engine

and check the jet intake for clogging. (See
page 106 for information on the jet intake.)
TIP
It will take about 60 seconds for the water
to reach the outlet after the engine is start-
ed.
Water discharge may not be constant
when the engine is running at idling speed.
If this occurs, apply a little throttle to make
sure that water discharges properly.
EJU40323Water separator
The water separator prevents water from en-
tering the fuel tank by collecting any water
that has entered the fuel tank breather hose if
the watercraft was capsized.
If water has collected in the water separator,
drain it by loosening the drain screw.
To drain water from the water separator:
(1) Place a drain pan or dry cloth under thewater separator.
(2) Gradually loosen the drain screw to drain the water. Catch the draining water in the
drain pan or soak it up with the dry cloth
so that it does not spill into the engine
compartment. If any water spills into the
watercraft, be sure to wipe it up with a
dry cloth. (3) Securely tighten the drain screw until it
stops.

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.
