RAW WATER SYSTEM
8.1 General
In the raw or seawater systems, the baitwell
and release well water pumps are mounted to
seacocks on thru-hull fittings located in the stern
bilge. The water system pressure pump is con-
nected to an auxiliary supply fitting at the base
of the starboard pump. Always make sure the
seacock valves are open before attempting to
operate any component of the raw water system.
Priming The System
Make sure both seacock valves are open and the
Raw Water switch in the helm switch panel is on.
Run the pressure pump by turning on the raw
water washdown hose until all of the air is purged
from the system. Then turn the hose off. Turn the
Starboard Release Well/Baitwell pump switch to
the ON position and run the pump until all of the
air is purged from the release well and baitwell
supply systems. Then turn the pump off. Repeat
this process to prime the port release well.
The intake fittings for the release well/baitwell
centrifugal pumps are an anti-venture design
with an ON/OFF valve. If a pump runs but will
not prime, make sure the valve is open. If the
pump still won’t prime, it may be air locked. Make
sure the valve is open and run the boat at or
above 15 M.P.H. Water pressure from the intake
fitting will force feed water to the pump pushing
the trapped air through the pump and allow it to
prime. If this procedure doesn’t work, contact
your Crevalle dealer.
Closing the thru-hull valves before the boat is
hauled from the water will help to eliminate air
locks in raw water systems. The valves should
also be closed whenever you leave the boat in the
water unattended.
Notice:
It may be necessary to reprime the raw wa -
ter system if it is not used for an extended
period and at the time of launching.
