Engine shut-off switch
Insert the clip 1, on the end of the engine
shut-off cord 2, under the engine shut-off
switch 3 (black button). The engine will stop
automatically when the clip is removed from
the switch, such as if the operator falls off
the watercraft.
WARNING@
Always attach the engine shut-off cord
to your wrist and the clip to the engine
shut-off switch BEFORE starting the
engine.

To prevent accidental starting of the
engine or unauthorized use by chil-
dren or others, always remove the clip
from the shut-off switch when the
engine is not running.

Cooling water pilot outlet
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 discharged from the pilot outlets.
To check for proper operation of the cool-
ing system, check that water is being dis-
charged from the port (left) pilot outlet. If
water is not being discharged from this out-
let, cooling water may not be circulating in
the engine. When this occurs, stop the
engine and check for the cause. (See pages
2-30 and 5-3 for further instructions.)
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.

Steering system
Your watercraft can be steered by turning
the handlebars 1 in the direction you wish
to travel.
When the handlebars are turned, the
angle of the jet thrust nozzle 2 is changed
and the direction 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, except at
trolling speed.
This model has the Yamaha Engine Man-
agement System (YEMS) that includes an
Off-Throttle Steering (OTS) system. It will
activate at planing speeds should you
attempt to steer the watercraft after releas-
ing 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.

Shift 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
watercraft to move in reverse or forward.
When the shift lever is in the reverse posi-
tion, the watercraft can be launched from a
trailer, or backed up out of tight spots where
you cannot turn around easily.
To shift into reverse:
1. Release the throttle and let the engine
speed return to idle.
2. Pull the shift lever toward you.
WARNING@
Make sure that the throttle 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 and let the engine
speed return to idle.
2. Push the shift lever away from you.

Quick Shift Trim System
(QSTS) selector
The QSTS selector 1 is located at the
left handlebar grip and is used to adjust the
trim angle of the watercraft.
Operating the QSTS selector changes the
angle of the jet thrust nozzle vertically. This
changes the trim angle of the watercraft.
There are 5 positions: 2 bow down posi-
tions A and B, neutral “N,” and 2 bow up
positions C and D.
To change the trim angle:
1. Reduce engine speed to 4,000 r/min or
less.
2. Squeeze the shift lock lever 2, and then
turn the QSTS selector to the desired
position.
3. Release the shift lock lever to lock the
QSTS selector.
CAUTION:@ Do not turn the QSTS selector while
operating the watercraft at full throttle,
otherwise damage could occur to the
QSTS.
@
The neutral “N” position will provide good
performance for most operating conditions.
To enhance particular types of perfor-
mance, select bow down or bow up.

Yamaha Engine Management
System (YEMS)
This model is equipped with an inte-
grated, computerized management system
that controls and adjusts ignition timing, fuel
injection, engine diagnostics, and the Off-
Throttle Steering (OTS) system.

Yamaha Security System/
Low-RPM mode
This watercraft is equipped with a remote
control transmitter 1 that is used to select
the security system and low-RPM mode set-
tings. Since the watercraft is programmed to
recognize the internal code from this trans-
mitter only, the security system setting can
only be changed with this transmitter. If you
lose the remote control transmitter or it does
not operate properly, contact a Yamaha
dealer.

Yamaha 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
engine can only be started in the unlock
mode.

Yamaha Security System lock and
unlock modes
The lock and unlock modes of this system
can only be selected while the engine is
stopped.
When the lock button 1 is pressed, the
beeper sounds once. This indicates the lock
mode is selected and the engine cannot be
started.
The “UNLOCK” indicator light 2 comes
on when the security system is in the unlock
mode and goes off when the security sys-
tem is in the lock mode.
When the unlock button 3 is pressed for
a short time, the beeper sounds two times
for the normal mode or three times for the
low-RPM mode. The “UNLOCK” indicator
light will come on and the engine can be
started. (See the items in “Selecting the nor-
mal mode/low-RPM mode” for operation
mode information.)

Selecting the normal mode/low-
RPM mode
The normal mode and low-RPM mode
can only be selected when the engine is
stopped in the unlock mode. Press the
unlock button for more than 4 seconds to
select the normal mode or low-RPM mode.
Normal mode
If the beeper sounds twice, the normal
mode is activated.
The watercraft can be ridden normally.
Low-RPM mode
If the beeper sounds three times, the low-
RPM mode is activated and the “L-MODE”
indicator light 1 comes on.
Maximum engine speed (r/min) in the low-
RPM mode is limited to approximately 80%
of the maximum engine speed in the normal
mode.
NOTE:@
If neither the start switch nor the remote
control transmitter is operated within
25 seconds after the unlock button is
pressed to select the unlock mode, the
multifunction meter display and the
“L-MODE” indicator light will go off. If this
occurs, press the lock button briefly to
select the lock mode, press the unlock
button briefly to select the unlock mode,
and then press the unlock button again for
more than 4 seconds to select the normal
mode or low-RPM mode.

While the engine is running, input from
the remote control transmitter is not
received.
