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 at the stern of the boat, either through the drive or 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 aer 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 one month.
Salt water boats should be ushed with fresh water aer 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.
