AFTER EACH USE
CHECK THE RAW WATER PICK-UP
For all Ilmor equipped boats, a check of the raw water pick-up is necessary.
Located beneath the boat, under the water line on the hull is the raw water
pick-up. Even when boating on clean-appearing bodies of water, a check
of this pick-up should be done aer every outing to determine if there is
any debris. is should be rinsed with fresh water prior to storage, even of
short duration. It will be easier to clean following an outing than waiting
and possibly allowing debris to dry.
FLUSH THE RAW WATER/SEA PUMP
SYSTEM
1. Place a ushing device on the raw water pick-up on the bottom of the
hull. Turn the garden hose ON and start the engine.
2. Cycle engine speed from idle to 2,000 rpm in 10-second intervals,
allowing the engine to reach operating temperature. e engine needs
to be at its operating temperature for 15 minutes. e garden hose ow
rate may need to be adjusted if engine will not warm up; it must warm
up to open the thermostat, which is required for proper ushing. If
the engine will not warm up, remove thermostat and ush engine with
fresh water for 5 minutes while cycling the engine speed from idle to
2,000 rpm in 10-second intervals.
Fresh water boats should be ushed when going to storage or not being
used for periods in excess of 1 month.
Salt water boats should be ushed with fresh water aer every use.
Boat-in-water ushing can be achieved with a ushing device. e seacock
will need to be closed while supplying fresh water to the inlet of the sea
pump and allowing it to circulate through the engine.
