in response to handlebar input until you apply
throttle again or you reach trolling speed.
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
85 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.

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.
EJU40322Water 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.

TIP:
Push the select button on the multifunction in-
formation center to stop the buzzer.
EJU31626Oil pressure warning
If the oil pressure drops significantly, the oil
pressure warning indicator and the “WARN-
ING” indicator light blink, and the buzzer
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 45 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.
TIP:
Push the select button on the multifunction in-
formation center to stop the buzzer.
EJU31609Engine 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 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
85 for information on the jet intake.) NOTICE:
If you cannot locate and correct the cause
of the overheating, consult a Yamaha deal-
er. Continuing to operate at higher speeds
could result in severe engine damage.

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 85 for in-
formation on the jet intake.)

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.
