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.
Avoid sharp turns or other maneuvers that
make it hard for others to avoid you or un-
derstand where you are going.
Avoid areas with submerged objects or
shallow water.
Take early action to avoid collisions. Re-
member, watercraft and other boats do not
have brakes.
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.
Never operate in water that is less than 60
cm (2 ft) deep from the bottom of the wa-
tercraft, otherwise you increase your chan-
ce of hitting a submerged object, which
could result in injury.
This watercraft is not equipped with light-
ing required for night operation. Do not op-
erate the watercraft after sunset or before
dawn, otherwise you increase the risk of
60 cm (2 ft)

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 muffler or engine dur-
ing or immediately after engine operation;
they can cause serious burns.
EJU30921
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.
This watercraft is water-jet propelled. The
jet pump is directly connected to the en-
gine. This means that jet thrust will produce
some movement whenever the engine is
running. There is no “neutral” position. You
are in either “forward” or “reverse”, de-
pending upon the shift lever position.
Do not use the reverse function to slow
d o w n o r s t o p t h e w a t e r c r a f t a s i t c o u l d c a u -
se you to lose control, be ejected, or im-
pact 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.

Watercraft glossary
Trolling speed
“Trolling” is the lowest maneuvering speed. You are applying little or no throttle. The water-
craft is down in the water, and there is no wake.
Sub-planing speed
“Sub-planing” is a medium speed. The bow of the watercraft is slightly up from the water sur-
face, but you are still traveling through the water. There is a wake.
Planing speed
“Planing” is a faster speed. The watercraft is more level and is skimming on top of the water.
There is a wake.
Bow
The front end of the watercraft.
Stern
The rear end of the watercraft.
Starboard
The right side of the watercraft when facing forward.
Port
The left side of the watercraft when facing forward.
Bilge water
Water that has collected in the engine compartment.
Yamaha Engine Management System (YEMS)
YEMS is an integrated, computerized management system that controls and adjusts ignition
timing, fuel injection, engine diagnostics, and the off-throttle steering (OTS) system.

will not start. Also, the starter motor could
be damaged.
[ECJ01041]
The engine will not start under any of the fol-
lowing conditions:
Lock mode of the Yamaha Security System
has been selected. (See page 26 for
Yamaha Security System setting proce-
dures.)
Clip is removed from the engine shut-off
switch.
Throttle lever is squeezed.EJU31212Throttle lever
The throttle lever increases the engine speed
when the lever is squeezed.
The throttle lever returns automatically to its
fully closed (idle) position when released.
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.
EJU37342Telescopic steering system
The position of the handlebars can be adjust-
ed up or down by operating the lock lever.
The handlebars can be adjusted to three po-
sitions.
To adjust the handlebar position:
(1) Pull the lock lever up to disengage the
handlebar lock, and then move the han-
dlebars up or down to the desired posi-
tion. WARNING! Never pull the lock
lever during operation, otherwise the
handlebars may suddenly change po-
sition, which may lead to an accident.
[EWJ01271]
(2) Make sure that the lock lever returns to
its original position and that the handle-
bars are securely locked in place.
EJU41801Cooling water pilot outlets
When the engine is running, some of the
cooling water that is circulated in the engine
is discharged from the cooling water pilot
outlets.
There are cooling water pilot outlets on the
port (left) and starboard (right) sides of the
watercraft. To check for proper operation of
the cooling system, make sure that water is
being discharged from the port (left) pilot out-
let. If water is not being discharged from the
outlet, stop the engine and check the jet in-
take for clogging. (See page 92 for informa-
tion on the jet intake.)

Turn the handlebars to the right and left sev-
eral times to make sure that operation is
smooth and unrestricted throughout the
whole range, and that the free play is not ex-
cessive.
Turn the handlebars as far as possible to the
right and left to make sure that the jet thrust
nozzle moves as the handlebars are turned,
and that there is no difference between theright and left fully turned positions of the jet
thrust nozzle.
Difference between fully turned posi-
tions of jet thrust nozzle (distances A
and B):
Maximum 5 mm (0.20 in)
