Cooling water pilot outlet
This watercraft is equipped with cooling
water pilot outlets.
When the engine is running, cooling
water is circulated in the engine, and then it
is discharged from the pilot outlets.
To check for proper operation of the cool-
ing system, check that water is being dis-
charged from the port (left) pilot outlet. If
water is not being discharged from this out-
let, cooling water may not be circulating in
the engine. When this occurs, stop the
engine and check for the cause. (See pages
2-24 and 5-3 for further instructions.)
NOTE:
@
● 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.
● Water discharge may not be constant at
the starboard (right) pilot outlet, however,
if it is constant at the port (left) pilot outlet,
the cooling system is operating normally.
