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.
EX / EX Sport: Take early action to avoid
collisions. Remember, watercraft and other
boats do not have brakes.
EX / EX Sport: Avoid sharp turns or other
maneuvers that make it hard for others to
avoid you or understand where you are go-
ing.
EX Deluxe: 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.
EX Deluxe: Avoid sharp turns, slowing
down rapidly by squeezing the RiDE lever
forcefully, and other maneuvers that make
it hard for others to avoid you or under-
stand 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—you need
throttle to steer. Always check throttle and
steering controls before starting the water-
craft.
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.
Sharp turns or jumping wakes or waves
can increase the risk of back/spinal injury
(paralysis), facial injuries, and broken legs,
ankles, and other bones. Do not jump
wakes or waves.
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.
As with any water sport, you should not op-
erate your watercraft without someone else
nearby. If you operate further than swim-
ming distance from shore, you should be
accompanied by another boat or water-
craft, but make sure you stay a safe dis-
tance away. It’s good, common sense.

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 51 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 personin 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-

Hazard information
Never start the engine or let it run for any
length of time in an enclosed area. Exhaust
fumes contain carbon monoxide, a color-
less, odorless gas that may cause loss of
consciousness and death within a short
time. Always operate the watercraft in an
open area.
Do not touch the hot oil tank, muffler, or en-
gine during or immediately after engine op-
eration; they can cause serious burns.
Do not place magnets or objects with a
strong magnetic force near the throttle le-
ver or RiDE lever (EX Deluxe). The electron-
ic throttle mechanism of the levers can be
adversely affected, which could cause loss
of control. In addition, do not place objects
susceptible to magnetic forces (i.e., credit
cards, watches, etc.) close to the throttle
lever or RiDE lever.
EJU44341
Watercraft characteristics
Jet thrust turns the watercraft. Releasing
the throttle lever completely produces only
minimum thrust. If you are traveling at
speeds above trolling, you will have rapidly
decreasing ability to steer without throttle.
This model is equipped with the Yamaha
Engine Management System (YEMS) that
includes an off-throttle steering (OTS) sys-
tem. 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 sharp-
ly if you apply throttle while turning the han-
dlebars.
The OTS system does not function below
planing speeds or when the engine is off.
Once the engine slows down, the water-
craft will no longer turn in response to han-
dlebar input until you apply throttle again or
you reach trolling speed.
Practice turning in an open area without
obstacles until you have a good feel for this
maneuver.
EX: This watercraft is water-jet propelled.
The jet pump is directly connected to the
engine. This means that jet thrust will pro-
duce some movement whenever the en-
gine is running. There is no “neutral”
position.
EX Sport: This watercraft is water-jet pro-
pelled. The jet pump is directly connected
to the engine. This means that jet thrust will
produce some movement whenever the
engine is running. There is no “neutral” po-
sition. You are in either “forward” or “re-
verse”, depending upon the shift lever
position.

EX Sport: Do not use the reverse function
to slow down or stop the watercraft as it
could cause you to lose control, be eject-
ed, or impact the handlebars.
This could increase the risk of back/spinal
injury (paralysis), facial injuries, and broken
legs, ankles, and other bones. You could
also damage the shift mechanism.
EX Sport: Reverse can be used to slow
down or stop during slow-speed maneu-
vering, such as when docking. Once the
engine is idling, shift into reverse and grad-
ually increase engine speed. Make sure
that there are no obstacles or people be-
hind you before shifting into reverse.
EX Deluxe: This watercraft is water-jet pro-
pelled. The jet pump is directly connected
to the engine. This means that jet thrust will
produce some movement whenever the
engine is running and the “F” (forward) or
“R” (reverse) shift indicator is displayed.
When the “N” (neutral) shift indicator is dis-
played, the forward and reverse thrust are
balanced to help keep the watercraft from
moving in either direction, although some
movement may occur.
EX Deluxe: To avoid rear-end collisions
while operating the watercraft, check be-
hind you before using the RiDE lever to
slow down or stop the watercraft. Makesure that there are no obstacles or people
behind you before 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.
