RAW WATER SYSTEM
8.1 General
A raw water manifold located in the aft systems
compartment bilge supplies seawater to the raw wa-
ter pumps. The intake for the manifold is equipped
with a ball valve that turns the raw water main
supply to the manifold on or off. Other ball valves
on the manifold enable the operator to turn the
water supply on or off for each individual pump in
the system. Always make sure all valves are open
before attempting to operate any component of the
raw water system.
WARNING
THE RAW WATER MANIFOLD IS PROVIDED WITH A FRESH
WATER FLUSH CONNECTION. VERIFY THAT THIS FLUSH
VALVE REMAINS CLOSED WHEN NOT IN USE. IF LEFT OPENED,
SEVERE FLOODING WILL OCCUR.
Priming the System
Make sure the ball valves are open and the Raw
Water pump switch is on. Run the pressure pump
by turning on the raw water washdown hose until all
of the air is purged from the system and then turn
the hoses off. Turn both Baitwell Pump switches on
and run the pumps until all of the air is purged from
the both systems and turn the pumps off.
The intake for the raw water manifold is equipped
with a scoop and ball 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. The water pressure from the scoop will
force the trapped air through the pump and allow
it to prime. If this procedure doesn’t work, contact
your Everglades 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 unat-
tended.
Notice:
It may be necessary to reprime the raw water
system if it is not used for an extended period
and at the time of launching.

8.2 Raw Water System Operation
A high pressure pump, controlled by a pressure
sensor, is activated by the Raw Water switch. When
activated, the pressure switch will automatically
control the pump that supplies the raw water hose
connectors.
As the pressure builds in the system, the pump will
shut off. When the system is in use and the pres -
