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 38 and 85 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.

transmitter. (See page 25 for information on
using the remote control transmitter.)
TIP:
The L-MODE can only be selected when the
engine is stopped in the unlock mode of the
Yamaha Security System.
Activating and deactivating the L-MODE
Activation of the L-MODE will be confirmed by
the number of beeps when the remote control
transmitter is operated, and by the “L-MODE”
indicator light of the dual analog meter unit.
(See page 35 for more information on the dual
analog meter unit.)
TIP:
If the remote control transmitter is operated
while the dual analog meter unit is in the
standby state, the unit performs the initial op-
eration, and then the setting is selected.
To activate 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 three times
and the “UNLOCK” indicator light blinks threetimes, then comes on, the “L-MODE” indicator
light comes on and the L-MODE is activated.
TIP:
If the L-MODE is selected immediately after
the information display turns off, the “L-
MODE” indicator light will not come on. The
“L-MODE” indicator light will come on when
the engine is started.
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).

To switch to the voltmeter from the hour
meter:
Push the “Hour Volt” button for at least 1 sec-
ond. The display switches from the hour
meter to the voltmeter.
EJU37270Fuel level meter
The fuel level meter is provided for convenient
fuel level checking while riding.
The fuel level meter has four segments which
show the amount of fuel remaining in the fuel
tank. The display segments of the fuel level
meter disappear one at a time as the fuel level
decreases.
TIP:
The fuel level is most accurate when the wa-
tercraft is sitting level on a trailer or in the wa-
ter.
EJU37280Fuel level warning
If the fuel remaining in the fuel tank drops to
about 18 L (4.8 US gal, 4.0 Imp. gal), the low-
est fuel level segment, the fuel indicator, and
the “WARNING” indicator light blink, and the
buzzer sounds intermittently.
If this occurs, refill the fuel tank as soon as
possible.
The warning signals will be cleared when the
engine is restarted after the fuel tank is re-
filled.
TIP:
Push the “Hour Volt” button to stop the buzz-
er.
EJU37290Oil pressure warning
If the oil pressure drops significantly, the
“WARNING” indicator light and the oil pres-
sure warning indicator blink, and the buzzer
sounds intermittently. At the same time, the

maximum engine speed is limited to help pre-
vent damage.
If this occurs, immediately reduce the engine
speed, return to shore, and then check the en-
gine oil level. (See page 47 for engine oil level
checking procedures.) If the oil level is suffi-
cient, have a Yamaha dealer check the water-
craft.
TIP:
Push the “Hour Volt” button to stop the buzz-
er.
EJU37300Engine overheat warning
If the engine temperature rises significantly,
the “WARNING” indicator light and the engine
overheat warning indicator blink, and the
buzzer sounds intermittently. Then, the
“WARNING” indicator light and the engine
overheat warning indicator stop blinking and
remain on, and the buzzer sounds continu-ously. After the light and indicator start to blink
and the buzzer sounds, the maximum engine
speed is limited to help prevent damage.
If this occurs, immediately reduce the engine
speed, return to shore, and then check for wa-
ter discharge at the port (left) cooling water pi-
lot outlets while the engine is running. If there
is no discharge of water, shut the engine off,
and then check the jet intake for clogging.
(See page 85 for jet intake cleaning proce-
dures.) NOTICE: If you cannot locate and
correct the cause of the overheating, con-
sult a Yamaha dealer. Continuing to oper-
ate at higher speeds could result in severe
engine damage.
