Identification numbers
Record the Primary Identification (PRI-ID)
number, Craft Identification Number (CIN),
and engine serial number in the spaces pro-
vided for assistance when ordering spare
parts from a Yamaha dealer. Also record and
keep these ID numbers in a separate place in
case your watercraft is stolen.
EJU30281Primary Identification (PRI-ID) number
The PRI-ID number is stamped on a plate at-
tached inside the engine compartment.

EJU36550Craft Identification Number (CIN)
The CIN is stamped on a plate attached to the

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.

To deactivate the L-MODE:
Press the “L-Mode” (unlock) button on the re-
mote control transmitter for more than 4 sec-
onds. Once the beeper sounds two times and
the “UNLOCK” indicator light blinks two times,
then comes on, the “L-MODE” indicator light
goes off and the L-MODE is deactivated.
When the L-MODE is deactivated, the water-
craft returns to the normal operation mode.
EJU37431Dual analog meter unit
The dual analog meter unit displays various
watercraft information.
Dual analog meter unit initial operation
When the dual analog meter unit starts oper-
ating, the speedometer and tachometer make
one sweep, all segments of the information
display and all indicator lights come on. After
2 seconds, the “WARNING” indicator light, the
“L-MODE” indicator light, and the warning in-
dicators in the information display go off, and
then the unit starts to operate normally.
TIP:
The “UNLOCK” indicator light will go off when
the engine is started.Dual analog meter unit standby state
If the dual analog meter unit does not receive
any operation input within 25 seconds after
the engine stops, the unit will turn off and en-
ter a standby state. When the engine is start-
ed again, the display and the indicator lights
will return to their state before the unit turned
off, and then the unit starts to operate normal-
ly.
EJU37440Speedometer
The speedometer shows the watercraft speed
against water.
The large inner numbers on the meter show
the watercraft speed in miles per hour “MPH”
and the small outer numbers show the speed
in kilometers per hour “km/h”.
EJU37240Tachometer
The tachometer shows the engine speed.
The large inner numbers on the meter show
the engine speed × 1000 RPM (r/min).

Operation
WARNING
EWJ00510
Before operating your watercraft, become
familiar with all of the controls. Consult a
Yamaha dealer about any control or func-
tion that you do not fully understand. Fail-
ure to understand how the controls work
could cause an accident or prevent you
from avoiding an accident.
NOTICE
ECJ00460
Make sure that the stern drain plugs are
tightened securely before launching the
watercraft.
EJU36661Engine break-in
NOTICE
ECJ00430
Failure to follow the engine break-in pro-
cedure could result in reduced engine life
or even severe engine damage.
The engine break-in period is essential to al-
low the various components of the engine to
wear and polish themselves to the correct op-
erating clearances. This ensures proper per-
formance and promotes longer component
life.
TIP:
Be sure to check the engine oil level before
operating the watercraft for the first time. (See
page 45 for engine oil checking procedures.)
(1) Launch the watercraft and start the en-
gine. (See page 53 for engine starting
procedures.)
(2) For the first 5 minutes, run the engine at
trolling speed only. For the 30 minutes of
operation after that, keep the engine
speed below 5000 r/min. For the 1 hour of
operation after that, keep the engine
speed below 6000 r/min.
(3) Proceed with normal operation.
EJU32801Launching the watercraft
When launching the watercraft, make sure
that there are no obstacles behind you.
Use the remote control transmitter to select
the unlock mode. (See page 31 for Yamaha
Security System lock and unlock mode selec-
tion procedures.)
After the watercraft is in the water, start the
engine. Shift into reverse and move the water-
craft back slowly. If there are waves, some-
one should make sure that the watercraft is
not pushed into the trailer before backing
away.
EJU36341Starting the engine
(1) If the lock mode of the Yamaha Security
System is selected, use the remote con-
trol transmitter to select the unlock mode.
(See page 31 for Yamaha Security Sys-
tem lock and unlock mode selection pro-
cedures.)
(2) Launch the watercraft in water free from
weeds and debris and at least 60 cm (2 ft)
deep from the bottom of the watercraft.
NOTICE: Never operate in water that is
less than 60 cm (2 ft) deep from the
bottom of the watercraft, otherwise
