(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 99 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

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 port (left) cooling
water 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 99 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.
[ECJ00042]
TIP:
While the engine overheat warning is acti-
vated, the maximum engine speed is limit-
ed.
Tap “ ” to display a description of the
warning in the center display.
Oil pressure warning “ ”
If the oil pressure drops significantly, the
warning bar is shown instead of the tachom-
eter value display, “ ” and “ ” are
shown, and the buzzer sounds intermittently.
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 58 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.
TIP:
While the oil pressure warning is activated,
the maximum engine speed is limited.
Tap “ ” to display a description of the
warning in the center display.
Other warnings (communication errors,
exceeding the maintenance intervals, and
so on) “ ”
If any other malfunction is detected or if the
engine has been operated for more than 50
hours since the last maintenance, the warn-
ing bar is shown instead of the tachometer
value display, “ ” is shown, and the buzz-
er sounds intermittently.
If a warning is activated, have the watercraft
serviced by a Yamaha dealer as soon as pos-
sible.
TIP:
Tap “ ” to display a description of the
warning in the center display.

EJU45260Multifunction information center check
Make sure that the multifunction information
center operates properly. (See page 39 for in-
formation on proper operation of the multi-
function information center.)
EJU43392Shift system check
Operate the throttle lever and RiDE lever, and
check that the watercraft moves or does not
move according to the displayed shift indica-
tor. (See page 29 for shift system operation
procedures.) WARNING! To avoid colli-
sions, operate at safe speeds and keep asafe distance away from people, objects,
and other watercraft.

EJU40242After removing the watercraft from
the water
NOTICE
ECJ01311
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 pas-
sages.
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.
(3) Stop the engine.
