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.
EJU30920
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 re-
leasing the throttle lever. The OTS system
assists in turning by continuing to supply
some thrust while the watercraft is deceler-
ating, but you can turn more sharply if you
apply throttle while turning the handlebars.
The OTS system 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.
Practice turning in an open area without ob-
stacles until you have a good feel for this
maneuver.
This watercraft is water-jet propelled. 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” position. You are in ei-
ther “forward” or “reverse”, depending upon
the shift lever position.
Do not use the reverse function to slow
down or stop the watercraft as it could
cause 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.

EJU36740Cooling water pilot outlets
This watercraft is equipped with cooling water
pilot outlets on the port (left) and starboard
(right) sides of the watercraft.
When the engine is running, cooling water is
circulated in the engine, and then it is dis-
charged from the pilot outlets.
To check for proper operation of the cooling
system, check that water is being discharged
from the port (left) pilot outlets. If water is not
being discharged from these outlets, cooling
water may not be circulating in the engine.
When this occurs, stop the engine and check
for the cause. (See pages 36 and 83 for more
information.)
TIP:
If the cooling water passages are dry, it will
take about 60 seconds for the water to
reach the outlets after the engine is started.
Water discharge may not be constant at
idle, therefore, open the throttle a little to
check that water discharges properly.
EJU31260Steering system
Your watercraft can be steered by turning the
handlebars in the direction you wish to travel.
When the handlebars are turned, the angle of
the jet thrust nozzle is changed, and the direc-
tion of the watercraft 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, ex-
cept 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 system 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 in-
put until you apply throttle again or you reach
trolling speed.
EJU37340Telescopic steering system
The position of the handlebars can be adjust-
ed up or down using the lock lever.
The handlebars can be adjusted to three po-
sitions.
To adjust the handlebar position:
(1) Pull the lock lever up, and then move the
handlebars up or down to the desired po-
sition. WARNING! Never pull the lock
lever during operation, otherwise the
handlebars may suddenly change po-
sition, which may lead to an accident.
[EWJ01270]
(2) Check that the lock lever returns to its
original position and that the handlebars
are locked in place.
EJU31301Shift lever
The shift lever is located on the starboard
(right) side of the watercraft and is used to
control the reverse gate, which allows the wa-
tercraft to move in reverse or forward.
When the shift lever is in the reverse position,
the watercraft can be launched from a trailer,
or backed up out of tight spots where you can-
not turn around easily.

Check the handlebars for looseness.
Turn the handlebars as far as possible to the
right and left to make sure that operation is
smooth and unrestricted throughout the
whole range. Also, make sure that the jet
thrust nozzle moves as the handlebars are
turned, and that there is no free play between
the handlebars and the jet thrust nozzle.
Pull the handlebars up and down to check that
the lock lever and handlebars are locked inplace. (See “Telescopic steering system” on
page 28 for more information.)EJU36581Shift lever and reverse gate

EJU36051
Turning the watercraft
WARNING
EWJ01100
Do not release the throttle lever when
trying to steer away from objects—you
need throttle to steer. A collision could
result in severe injury or death.
When operating at higher speeds, make
gradual turns or slow down before turn-
ing. Sharp high-speed turns may cause
the watercraft to slide sideways or spin,
throwing the operator and passenger
overboard, which could cause an injury.
Steering control depends on the combination
of handlebar position and the amount of throt-
tle.
Water sucked in through the intake grate is
pressurized by the impeller in the jet pump. As
the pressurized water is expelled from the
pump through the jet thrust nozzle, it creates
thrust to move and steer the watercraft. The
higher the engine speed, the more thrust pro-
duced.
The amount of jet thrust, in addition to the po-
sition of the handlebars, determines how
sharply you turn.A. More throttle produces higher thrust, so
the watercraft will turn more sharply.
B. Less throttle produces lower thrust, so
the watercraft will turn more gradually.
C. 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. You may still have some
turning ability immediately after releasing
the throttle lever, but once the engine
slows down, the watercraft will no longer
respond to handlebar input until you ap-
ply throttle again or you reach trolling
speed.
At trolling speed, the watercraft can be
turned gradually by handlebar position

alone using just the amount of thrust
available at idle.
D. If the engine is stopped while riding, there
is no thrust. The watercraft will go straight
even though the handlebars are turned.
You need throttle to steer.
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 (see condition C above).
The OTS system assists in turning by continu-
ing to supply some thrust while the watercraft
is decelerating, but you can turn more sharply
if you apply throttle while turning the handle-
bars. The OTS system does not function be-
low planing speeds or when the engine is off.
Once the engine slows down, the watercraft
will no longer turn in response to handlebar in-put until you apply throttle again or you reach
trolling speed.
EJU37510Stopping the watercraft
The watercraft is not equipped with a sepa-
rate braking system. It is stopped by water re-
sistance when the throttle lever is released.
From full speed, the watercraft comes to a
complete stop in approximately 130 m (430 ft)
after the throttle lever is released or the en-
gine is stopped, although this distance will
vary depending on many factors, including
gross weight, water surface conditions, and
wind direction. The watercraft slows down as
soon as the throttle lever is released, but will
coast for a distance before fully stopping. If
you are not sure you can stop in time before
hitting an obstacle, apply throttle and turn in
another direction.
WARNING
EWJ00740
Allow adequate stopping distance.
Take early action to avoid collisions. Re-
member, watercraft and other boats do
not have brakes.
Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft to give you
time to stop.
Do not shut the engine off when slowing
down in case you need engine power to
130 m (430 ft)
