(2) Make sure that the tilt lever returns to its
original position and that the handlebars
are securely locked in place.
EJU35975Cooling water pilot outlet
When the engine is running, some of the
cooling water that is circulated in the engine
is discharged from the cooling water pilot
outlet.
There is a cooling water pilot outlet on the
port (left) side of the watercraft. To check for
proper operation of the cooling system, make
sure that water is being discharged from the
cooling water pilot outlet. If water is not being
discharged from the outlet, stop the engine
and check the jet intake for clogging. (See
page 102 for information on the jet intake.)
TIP:
It will take about 60 seconds for the water
to reach the outlet after the engine is start-
ed.
Water discharge may not be constant
when the engine is running at idling speed.
If this occurs, apply a little throttle to make
sure that water discharges properly.
EJU40323Water separator
The water separator prevents water from en-
tering the fuel tank by collecting any water
that has entered the fuel tank breather hose if
the watercraft was capsized.
If water has collected in the water separator,
drain it by loosening the drain screw.
To drain water from the water separator:
(1) Place a drain pan or dry cloth under the
water separator.
(2) Gradually loosen the drain screw to drain
the water. Catch the draining water in the
drain pan or soak it up with the dry cloth
so that it does not spill into the engine
compartment. If any water spills into the
watercraft, be sure to wipe it up with a
dry cloth.
(3) Securely tighten the drain screw until it
stops.1Cooling water pilot outlet

ously. At the same time, 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
being discharged from the cooling water pilot
outlet while the engine is running. If there is
no discharge of water, stop the engine, and
then check the jet intake for clogging. (See
page 102 for information on the jet intake.)
NOTICE: 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.

EJU42281Check engine warning
If a sensor malfunction or a short circuit is de-
tected, the check engine warning indicator

the buzzer sounds intermittently.
If the check engine warning is activated, im-
mediately reduce the engine speed, return to
shore, and have a Yamaha dealer check the
engine.

multifunction information center to stop the
buzzer.

To discharge water from the cooling water
passages:
(1) Make sure that the area around the wa-
tercraft is clear, and then start the en-
gine.
(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.
