Cooling water pilot outlet
This watercraft is equipped with a cooling
water pilot outlet on the port (left) side of the
watercraft.
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 cooling system,
check that water is being discharged from
the pilot outlet. If water is not being dis-
charged 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 2-9 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.

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 water-
craft is changes 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.

Steering pole
The steering pole varies in height with the
operator’s posture, enabling the operator to
assume various riding positions.
When removing the hood for pre-opera-
tion checks, maintenance, etc., lift the steer-
ing pole 1 and use the lock pin 2 to
support it. Move the lock pin into the detent.
Make sure the lock pin is returned to the
stowed position after installing the hood.

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.
