Clip with cord
First, place the boat in the water to pro-
vide adequate engine cooling. Start the
engine, and then remove the engine
shut-off switch clip, and verify that the
engine stops.
Refer to pages 3-15 to 3-17, “STARTING
THE ENGINES,” for information on
proper operation of the starter switch.
Cooling-Water Pilot Outlets
Check that water comes out from the
pilot outlets while engine is running in
the water. Refer to page 2-13 for correct
operation of the device.
TIP: It may take up to 20 seconds for
water to reach the pilot outlets when
first launching the boat. The amount
and force of the exiting water will vary
with engine rpm.
A continuous flow of water from
the pilot hole shows that water is
flowing through the engine cooling
passages. If water is not flowing out
of the pilot hole during operation,
do not continue to run the engines.
Overheating and serious damage
could occur. See Overheat Warning
System, page 2-13, for more informa-
tion.
