System lock and unlock mode selection pro-
cedures.)
EJU31210Throttle lever
Squeeze the throttle lever to increase engine
speed.
Release the throttle lever to decrease engine
speed or to return it to the idle position.
EJU31240Cooling water pilot outlets
This watercraft is equipped with cooling water
pilot outlets.
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 outlet. If water is not
being discharged from this outlet, cooling wa-
ter may not be circulating in the engine. Whenthis occurs, stop the engine and check for the
cause. (See pages 40 and 94 for more infor-
mation.)
NOTE:

If the cooling water passages are dry, it will
take about 60 seconds for the water to
reach the outlet 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.

Water discharge may not be constant at the
starboard (right) pilot outlet, however, if it is
constant at the port (left) pilot outlet, the
cooling system is operating normally.
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 determines1Throttle lever

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.
EJU31290Tilt lever
The tilt lever is located in front of the glove
compartment and is used to adjust the tilt of
the handlebars.To adjust the tilt, pull the tilt lever up, and then
move the handlebars up or down to the de-
sired position.
WARNING
EWJ00040

Never touch the tilt lever during opera-
tion, otherwise the handlebars may sud-
denly change position, which may lead
to an accident.

Make sure that the tilt lever returns to its
original position and that the handlebars
are locked in place after adjusting them,
otherwise the handlebars may suddenly
change position, which may lead to an
accident.
EJU31300Shift 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.
To shift into reverse:
(1) Release the throttle lever and let the en-
gine speed return to idle.
(2) Pull the shift lever toward you.
WARNING
EWJ00030

Make sure that the throttle lever is com-
pletely released and that the engine is at
idle before shifting into reverse.

Do not use the reverse function to slow
down or stop the watercraft as it could
cause you to lose control, be ejected, or
impact the handlebars.

Use reverse for slow-speed maneuver-
ing only.

Make sure that there are no obstacles or
people behind you before shifting into
reverse.

Do not touch the reverse gate while the
shift lever is being operated, otherwise
you could be pinched.
To shift into forward:
(1) Release the throttle lever and let the en-
gine speed return to idle.
(2) Push the shift lever away from you.
EJU31320Quick Shift Trim System (QSTS)
selector
The QSTS selector is located at the left han-
dlebar grip and is used to adjust the trim angle
of the watercraft.
Operating the QSTS selector changes the an-
gle of the jet thrust nozzle vertically. This
changes the trim angle of the watercraft.

There are 5 positions: 2 bow-down positions
(a) and (b), neutral “N”, and 2 bow-up posi-
tions (c) and (d).
To change the trim angle:
(1) Reduce engine speed to 4000 r/min or
less.
(2) Squeeze the QSTS selector lock lever,
and then turn the QSTS selector to the
desired position.
(3) Release the lock lever to lock the QSTS
selector.
CAUTION:
ECJ00010
Do not turn the QSTS selector while oper-
ating the watercraft at full throttle, other-
wise damage could occur to the QSTS.
The neutral “N” position will provide good per-
formance for most operating conditions.To enhance particular types of performance,
select bow down or bow up.
EJU31330Bow down
Turn the QSTS selector to (a) or (b) and the
bow will go down while the watercraft is on
plane.
Bow down puts more of the bow in the water.
This gives the watercraft more “hook”, which
enhances turning performance. This position
will also help the watercraft get up on plane
more quickly.
At higher speeds, however, the watercraft will
have a greater tendency to “bow steer” and
follow waves and wakes in the water. Fuel
economy and maximum speed are also re-
duced.
EJU31340Bow up
Turn the QSTS selector to (c) or (d) and the
bow will go up while the watercraft is on plane.
Bow up puts less of the bow in the water.
There is less water resistance, so straight-

(YEMS)
This model is equipped with an integrated,
computerized management system that con-
trols and adjusts ignition timing, fuel injection,
engine diagnostics, and the off-throttle steer-
ing (OTS) system.
EJU36290Yamaha Security System
The Yamaha Security System functions to
help prevent unauthorized use or theft of the
watercraft. The engine cannot be started if the
security system is in the lock mode. The en-
gine can only be started in the unlock mode.
This watercraft is equipped with a remote con-
trol transmitter that is used to select the lock
and unlock modes of the security system.
Since the watercraft is programmed to recog-
nize the internal code from this transmitter
only, the security system mode can only be
changed with this transmitter.
