in response to handlebar input until you apply
throttle again or you reach trolling speed.
EJU31293Adjustable tilt steering system
The position of the handlebars can be adjust-
ed back and forth by operating the tilt lever.
To adjust the handlebar position:
(1) Pull the tilt lever up to disengage the han-
dlebar lock, and then move the handle-
bars back or forth to the desired position.
WARNING! Never pull the tilt lever dur-
ing operation, otherwise the handle-
bars may suddenly change position,
which may lead to an accident.
[EWJ00041]
(2) Make sure that the tilt lever returns to its
original position and that the handlebars
are securely locked in place.
EJU35974Cooling water pilot outlet
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 outlet.
There is a cooling water pilot outlet on the port
(left) side of the watercraft. To check for prop-
er operation of the cooling system, make sure
that water is being discharged from the cool-
ing water pilot outlet. If water is not being dis-
charged from the outlet, stop the engine and
check the jet intake for clogging. (See page
96 for information on the jet intake.)
TIP:

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

tion center to stop the buzzer.
EJU35126Oil 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
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.

Push any button on the multifunction informa-
tion center to stop the buzzer.
EJU37601Engine 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 blinkand the buzzer sounds, the 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 96 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.

(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 96 for in-
formation on the jet intake.)
EJU40241After removing the watercraft from the
water
NOTICE
ECJ01310

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.

Post-operation care
WARNING
EWJ00330
Always place the watercraft upright in a
horizontal position when storing it, other-
wise fuel could leak out into the engine or
engine compartment, which could create a
fire hazard.
After using the watercraft, always take it out of
the water, clean it, and store it. Leaving the
watercraft in the water for extended periods
will accelerate the rate of normal deterioration
of the jet pump and hull. Marine organisms
and corrosion are some of the conditions that
can shorten the life of many watercraft com-
ponents.
