fort and safety, please ensure that you obtain
proper training or practice before operating
the watercraft by yourself. In addition, a
Yamaha dealer or boating organization will be pleased to recommend local sea schools, or
competent instructors.
In this manual, information of particular im-
portance is distinguished in the following
ways:
This is the safety alert symbol. It is used

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
cause you to be thrown off. Do not jump
waves or wakes—jumping can cause inju-
ries such as back or spinal injuries (paraly-
sis), facial injuries, and broken legs, ankles,
and other bones. Improper operation can
result in severe 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.

Safety information

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
cause choking, severe and permanent
neck injuries, 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 69 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-
