Post-launch checks

Perform the post-launch checks in the pre-op-
eration checklist while the boat is in the water
and the engine is running.

operation.

mation on starting the engine.)

remove the clip from the engine shut-off
switch to make sure that the engine stops
immediately.

Pre-operation checks

Cooling water pilot outlet check

Check that water comes out from the pilot out-
let while the engine is running in the water. If
water is not circulating, something may be
clogging the intake grate. Refer to "Jet pump
clean-out procedure" on page 123.
TIP:
It may take up to 20 seconds for water to
reach the pilot outlet when first launching the
boat. The amount and force of the exiting wa-
ter will vary with engine speed.
NOTICE
A continuous flow of water from the pilot
outlet shows that water is flowing through
the engine cooling water passages. If wa-
ter is not flowing out of the pilot outlet dur-
ing operation, do not continue to run the
engine. Overheating and serious damage
could occur. See "Engine overheat warn-
ing system" on page 41 for more informa-
tion.
