Push the start switch (green button) to start
the engine.
The engine will not start under any of the fol-
lowing conditions:

Squeeze the throttle lever to increase engine
speed.
Release the throttle lever to decrease engine
speed or to return it to the idle position.
EJU35971Cooling water pilot outlet
This watercraft is equipped with a cooling wa-
ter pilot outlet.
When the engine is running, cooling water is
circulated in the engine, and then it is dis-
charged 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 oc-
curs, stop the engine and check for the cause.
(See pages 33 and 78 for more information.)
TIP:

If the cooling water passages are dry, it will
take about 60 seconds for the water to
reach the outlet after the engine is started.

Water discharge may not be constant at
idle, therefore, open the throttle a little to
check that water discharges properly.

help prevent unauthorized use or theft of the

nize the internal code from this transmitter

remote control transmitter or if it does not op-
erate properly, contact a Yamaha dealer.

mote control transmitter.)
