in response to handlebar input until you apply
throttle again or you reach trolling speed.
EJU37341Telescopic steering system
The position of the handlebars can be adjust-
ed up or down by operating the lock lever.
The handlebars can be adjusted to three po-
sitions.
To adjust the handlebar position:
(1) Pull the lock lever up to disengage the
handlebar lock, and then move the han-
dlebars up or down to the desired posi-
tion. WARNING! Never pull the lock
lever during operation, otherwise the
handlebars may suddenly change po-
sition, which may lead to an accident.
[EWJ01270]
(2) Make sure that the lock lever returns to its
original position and that the handlebars
are securely locked in place.
EJU41800Cooling water pilot outlets
When the engine is running, some of the cool-
ing water that is circulated in the engine is dis-
charged from the cooling water pilot outlets.
There are cooling water pilot outlets on the
port (left) and starboard (right) sides of the
watercraft. To check for proper operation of
the cooling system, make sure that water is
being discharged from the port (left) pilot out-
let. If water is not being discharged from the
outlet, stop the engine and check the jet in-
take for clogging. (See page 92 for informa-
tion on the jet intake.)
TIP:

It will take about 60 seconds for the water to
reach the outlets after the engine is started.

sounds intermittently. At the same time, the
maximum engine speed is limited.
If the oil pressure warning is activated, imme-
diately reduce the engine speed, return to
shore, and then check the engine oil level.
(See page 51 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.
TIP:
Push the “Hour Volt” button to stop the buzz-
er.
EJU37303Engine overheat warning
If the engine temperature rises significantly,
the engine overheat warning indicator and the
“WARNING” indicator light blink, and the
buzzer sounds intermittently. Then, the en-
gine overheat warning indicator and the
“WARNING” indicator light stop blinking and
remain on, and the buzzer sounds continu-
ously. At the same time, the maximum engine
speed is limited.If the engine overheat warning is activated,
immediately reduce the engine speed, return
to shore, and then make sure that water is be-
ing discharged from the port (left) cooling wa-
ter pilot outlet while the engine is running. If
there is no discharge of water, stop the en-
gine, and then check the jet intake for clog-
ging. (See page 92 for information on the jet
intake.) 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.
[ECJ00041]
TIP:
Push the “Hour Volt” button to stop the buzz-
er.
EJU37312Check engine warning
If a sensor malfunction or a short circuit is de-
tected, the check engine warning indicator
and the “WARNING” indicator light blink, and
the buzzer sounds intermittently.

EJU41440Hood check
Push down on the rear of the hood and make
sure that it is securely closed.
EJU40144Post-launch checks
Perform the post-launch checks in the pre-op-
eration checklist while the watercraft is in the
water and the engine is running.
To perform the post-launch checks:
(1) Launch the watercraft. (See page 67 for
information on launching the watercraft.)
(2) Perform the checks and make sure that
there are no malfunctioning items or oth-
er problems.
EJU41810Cooling water pilot outlet check
Make sure that water is discharged from the
port (left) cooling water pilot outlet while the
engine is running. (See page 30 for informa-
tion on the cooling water pilot outlets.)
EJU37451Dual analog meter unit check
Make sure that the dual analog meter unit op-
erates properly. (See page 36 for information
on proper operation of the dual analog meter
unit.)
EJU41330Engine idling speed check
Start the engine and warm it up. Use the ta-
chometer in the dual analog meter unit to
make sure that the engine idling speed is not
significantly above or below the specified
range.
Engine idling speed:
1250 ±100 r/min

to avoid. A collision could result in se-
vere injury or death.
[EWJ00601]
(4) Come alongside the dock and get off the
watercraft.
EJU37193Operating in weeded areas
Always avoid using your watercraft in areas
where weed growth is thick. If operating in
weeded areas is unavoidable, alternately
squeeze the throttle lever and relax your grip
on the throttle lever to vary the engine speed.
Weeds tend to become clogged more when
operating at a steady speed and at trolling
speed. If weeds may have clogged the intake
area, clean the jet intake. (See page 92 for in-
formation on the jet intake.)
EJU40241After removing the watercraft from the
water
NOTICE
ECJ01310
Do not run the engine over 4000 r/min on
land. Also, do not run the engine for more
than 15 seconds without supplying water,
otherwise the engine could overheat.
After operating and removing the watercraft
from the water, promptly discharge the re-
maining water from the cooling water passag-
es.
To discharge water from the cooling water
passages:
(1) Make sure that the area around the wa-
tercraft is clear, and then start the engine.
(2) Discharge the remaining water out of the
cooling water passages by alternately
squeezing and releasing the throttle lever
quickly for 10 to 15 seconds.
(3) Stop the engine.
