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 a cooling
water pilot outlet.
When the engine is running, cooling
water is circulated in the engine, and then it
is discharged from the pilot outlet.
To check for proper operation of the cool-
ing system, check that water is being dis-
charged from the pilot outlet. If water is not
being discharged from the outlet, cooling
water may not be circulating in the engine.
When this occurs, stop the engine and check
for the cause. (See pages 2-16 and 5-4 for
further instructions.)
NOTE:
If the cooling water passages are dry, it will
take about 20 seconds for the water to reach
the outlet after the engine is started.
EJU00356
Steering system
Your watercraft can be steered by turning
the handlebars 1 the same 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
direction of a turn, the throttle must always
be open when attempting a turn, except at
trolling speed.

Shift lever
The shift lever is located on the starboard
side of the watercraft and is used to control
the reverse gate, which allows the watercraft
to move into reverse or forward.
When in the reverse position, the water-
craft 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, and then 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 then 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-
tionsA and B, neutral “N,” and 2 bow up
positionsC and D.
To change the trim angle:
1. Reduce engine speed to 3,000 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.

Engine overheat warning
system
This model is equipped with an engine
overheat warning system.
If the engine starts to overheat, the warn-
ing light, the indicator for the water tempera-
ture symbol, and “W.TEMP” display begin to
blink, the buzzer sounds, and the engine
speed will be limited to about 3,000 r/min.
When this occurs, check for water dis-
charge at the cooling water pilot outlet. If
there is no discharge of water, reduce the
engine speed and beach the watercraft, and
then check the intake grate and impeller for
clogging.
WARNING
Before attempting to remove weeds or
debris from the intake grate or impeller,
shut the engine off and remove the clip
from the engine shut-off switch. Severe
injury or death could result from coming
in contact with the rotating parts of the
jet pump.
CAUTION:
If you cannot locate and correct the
cause of the overheating, consult a
Yamaha dealer. Continuing to operate at
higher speeds could result in severe
engine damage.
NOTE:
Press any button on the multifunction meter
to stop the buzzer.

meter for operation on land. The
engine could overheat.
●Use the specified resistor-type spark
plugs and caps, otherwise the meter
may function erratically.
NOTE:

PADLOC (Programmable
digital locking ignition)
This feature is provided to deter unautho-
rized use.
The function allows you to choose either
“START” or “LOCK” mode, as the situation
requires, much as you would use an ignition
key in a motor vehicle. If you have previously
chosen “LOCK” mode, the engine will not
start unless the right code is put in to select
“START” mode.
NOTE:
If you do not use the PADLOC system, it is
unnecessary to perform the initial setting of
the PADLOC. In this case, the “START”
mode is automatically selected.
PADLOC initial setting
1. Remove the cover 1 in the front storage
compartment. Disconnect the blue con-
nector2 behind the front storage com-
partment.
2. After the warning light turns on, press
the “MODE” button for at least 3 seconds
until the display shows “COdE.” You are
ready to set your code.

3. Enter your four-letter code by pressing
the “A/SET,” “B,” or “C” buttons in the
right sequence.
NOTE:
If you do not press a button for more than
10 seconds, the display automatically turns
off. This cancels the process of selecting the
mode.
4. If the code entered is correct, the mode
will change from the previous mode to
either “START” or “LOCK.” Then the
mode display and buzzer will operate for
2 seconds.
NOTE:
●Once you select a mode, the mode will
not change unless you perform this mode
selection sequence again.
●If the wrong code is entered, the mode
display shows “ERROR” for 2 seconds
and the buzzer will sound 5 times. Then
the display returns to “COdE.”
