RAW WATER SYSTEM
8.1 General
A raw water manifold located in the mechanical
systems compartment bilge supplies seawater to
the raw water pumps. The intake for the mani-
fold is equipped with a ball valve that turns the
raw water main supply to the manifold on or off.
Other ball valves at each connection on the mani-
fold enable the operator to turn the water supply
on or off for each individual pump in the system.
Always make sure all ball valves are open before
attempting to operate any component of the raw
water system.
Priming the System
Make sure the ball valves are open and the Salt-
water Pump 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 and then turn the hose
off. Turn both Livewell 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 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.
8.2 Raw Water System Operation
A high pressure pump, controlled by a pressure
sensor, is activated by the Saltwater Pump switch
in the helm switch panel. When activated, the
Chapter 8:
pressure switch will automatically control the
pump that supplies the raw water faucets and
hose connectors.
As the pressure builds in the system, the pump
will shut off. When the system is in use and the
pressure drops, the pump will turn on. The water
pump is equipped with a strainer on the intake
side of the pump. The strainer should be checked
frequently and cleaned as necessary.
