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.

To enhance particular types of performance,
select bow down or bow up.
EJU31330Bow down
Turn the QSTS selector to (a) or (b) and the
bow will go down while the watercraft is on
plane.
Bow down puts more of the bow in the water.
This gives the watercraft more “hook”, which
enhances turning performance. This position
will also help the watercraft get up on plane
more quickly.
At higher speeds, however, the watercraft will
have a greater tendency to “bow steer” and
follow waves and wakes in the water. Fuel
economy and maximum speed are also re-
duced.
EJU31340Bow up
Turn the QSTS selector to (c) or (d) and the
bow will go up while the watercraft is on plane.Bow up puts less of the bow in the water.
There is less water resistance, so straight-
ahead acceleration when on plane and top
speed are enhanced.
In some conditions, however, the watercraft
may tend to “porpoise” (hop in the water). If
the watercraft is porpoising, select neutral or
bow down.
EJU31350Handgrip
The handgrip provides a handhold for board-
ing the watercraft.
WARNING
EWJ00020
Do not use the handgrip to lift the water-
craft. The watercraft could fall, which
could result in severe injury.
EJU34870Bow eye

speeds. If this occurs, the “WARNING” light
and the engine overheat warning indicator
come on and the buzzer sounds continuously.
In addition, the warning system will cut the ig-
nition to the engine to reduce the risk of se-
vere overheating. The engine cannot be
started until it cools down, so it may be neces-
sary to have the watercraft towed back to the
shore. (See “Towing the watercraft” on page
78 for towing procedures.)
The warning signals will be cleared when the
engine is restarted after it has cooled down.
NOTE:
If multiple warnings occur at the same time,
their priority is as follows:
(1) Final engine overheat warning
(2) Fuel level warning
(3) Oil level warning
(4) Initial engine overheat warning
(5) Exhaust temperature warning
(6) Check engine warning
