Cooling water pilot outlet
This watercraft is equipped with a cooling
water pilot outlet.
When the engine is running, cooling
water is circulated in the engine, and then it
is discharged from the pilot outlet.
To check for proper operation of the cool-
ing system, check that water is being dis-
charged from the pilot outlet. If water is not
being discharged from the outlet, cooling
water may not be circulating in the engine.
When this occurs, stop the engine and check
for the cause. (See pages 2-11 and 5-3 for
further instructions.)
NOTE:
If the cooling water passages are dry, it will
take about 20 seconds for the water to reach
the outlet after the engine is started.
EJU00356
Steering system
Your watercraft can be steered by turning
the handlebars 1 the same direction you
wish to travel.
When the handlebars are turned, the
angle of the jet thrust nozzle 2 is changed,
and the direction of the watercraft is
changed accordingly. Since the strength of
the jet thrust determines the speed and
direction of a turn, the throttle must always
be open when attempting a turn, except at
trolling speed.

Engine overheat warning
system
This model is equipped with an engine
overheat warning system.
If the engine starts to overheat, the
engine speed will be limited to about
3,000 r/min.
When this occurs, check for water dis-
charge at the cooling water pilot outlet. If
there is no discharge of water, reduce the
engine speed and beach the watercraft, and
then check the intake grate and impeller for
clogging.
WARNING
Before attempting to remove weeds or
debris from the intake grate or impeller,
shut the engine off and remove the clip
from the engine shut-off switch. Severe
injury or death could result from coming
in contact with the rotating parts of the
jet pump.
CAUTION:
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
engine damage.

EJU00371
Oil level warning lamp
If the oil remaining in the tank drops to
about 1.2 L (0.31 US gal, 0.26 Imp gal) or
the oil filter is clogged, the oil level warning
lamp begins to blink.
If the oil level warning lamp begins to
blink, refill with engine oil as soon as possi-
ble.
NOTE:
●The lamp will light up for 2 seconds after
starting the engine to check the lamp
operation.
●If the warning lamp blinks with adequate
oil in the tank, check for a clogged oil fil-
ter.
