WARNING
EWJ00010

Always attach the engine shut-off cord
to your left wrist and the clip to the en-
gine shut-off switch BEFORE starting

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 pilot outlets. If water is not being dis-
charged from the outlets, cooling water may
not be circulating in the engine. When this oc-
curs, stop the engine and check for the cause.
(See pages 29 and 76 for more information.)
NOTE:
If the cooling water passages are dry, it will
take about 20 seconds for the water to reach
the outlets after the engine is started.
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.
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.
EJU31310Quick 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 3000 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.

of the watercraft.
The stern rope holes are used to attach a rope
to the watercraft when transporting or moor-
ing it.
EJU31370Yamaha Engine Management System
(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.
EJU31420Multifunction information center
This meter contains the following functions for
help and convenience in operating the water-
craft.
CAUTION:
ECJ00060

Do not run the engine over 4000 r/min
when checking the operation of the
meter on land without supplying water,
otherwise the engine could overheat
and the catalytic converter could be se-
riously damaged.

Use the specified resistor-type spark
plugs and caps, otherwise the meter
may function erratically.
NOTE:

When the engine is started, all displays light
up for a few seconds, the buzzer sounds
twice, and then the meter starts to operate
normally.

The meter shows the hours of engine opera-
tion that have elapsed since the watercraft
was new.
Voltmeter
The voltmeter is provided to display the volt-
age of the battery.
The voltmeter displays 12 volts or more when
the battery voltage is within specification.
If the voltage displayed is low, return to shore
and, if necessary, have a Yamaha dealer
check the charging system and the battery.
EJU31560Fuel level warning indicator
If the fuel remaining in the fuel tank drops to
about 13 L (3.4 US gal, 2.9 Imp gal), the low-
est two fuel level segments, the fuel level
warning indicator, and the “WARNING” light
begin to blink. The buzzer also starts sound-
ing 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.

If the oil remaining in the oil tank drops to
about 1.7 L (0.45 US gal, 0.37 Imp gal) or the
oil filter is clogged, the oil level warning indica-
tor and the “WARNING” light begin to blink.The buzzer also starts sounding intermittent-
ly.
If this occurs, refill the oil tank as soon as pos-
sible.
The warning signals will be cleared when the
engine is restarted after the oil tank is refilled.
NOTE:
If the oil level warning indicator and the
“WARNING” light blink when there is ade-
quate oil in the oil tank, have a Yamaha dealer
check the oil filter for dirt and clogs.
EJU31580Engine overheat warning indicator
This model is equipped with an engine over-
heat warning system.
If the engine starts to overheat, the “WARN-
ING” light and the engine overheat warning in-
dicator begin to blink, and the buzzer sounds
intermittently.
If this occurs, reduce the engine speed, return
to shore, and then check for water discharge

at the cooling water pilot outlet while the en-
gine is running. If there is no discharge of wa-
ter, shut the engine off, and then check the
intake grate and impeller for clogging.
WARNING
EWJ00050
Before attempting to remove weeds or de-
bris from the intake grate or impeller, shut
the engine off and remove the clip from the
engine shut-off switch. Severe injury ordeath could result from coming in contact
with the rotating parts of the jet pump.
CAUTION:
ECJ00800
This watercraft is equipped with a catalytic
converter.

If the “WARNING” light, engine overheat
warning indicator, and buzzer come on,
reduce the engine speed and return to
shore. If you ignore these signals, the
engine will stop running and cannot be
restarted until the exhaust system cools
down.

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 en-
gine damage.
If the overheat warning is ignored, engine and
exhaust system heat may increase, particu-
larly if the watercraft is operated at higher
