RAW WATER SYSTEM
6.1 General
In the raw or sea water systems, all water pumps are supplied
by hoses connected to ball valves and thru‑hull fittings
located in the in the engine compartment bilge. Always make
sure the ball valves are open before attempting to operate any
component of the raw water system. 12-volt pumps supply
sea water to most of the various accessories.
The air conditioner uses a 120-volt AC sea water supply pump.
This is the only AC pump in the system and is activated by
the Air Conditioning breaker whenever the air conditioning
system is in use.
Priming the System
Make sure the ball valves are open. Open the hose connector
for the raw water washdown and activate the pressure pump
by turning the Washdown Pump breaker and the Washdown
switch to the “ON” position. Run the pump until all of the
air is purged from the system and then turn the switch off.
Turn the Livewell breaker and Baitwell switch to the “ON”
position. Run the pump until all of the air is purged from the
system and then turn the switch off.
The intake for the air conditioner raw water pump is equipped
with a scoop and ball valve. If the pump runs but will not
prime after cleaning the strainer or at the time of launching,
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
Albemarle dealer.
Closing the thru-hull ball valves before the boat is hauled
from the water will help to eliminate air locks in raw water
systems.
Note: It may be necessary to reprime the raw water
system if the system is not used for an extended
period and at the time of launching.
6.2 High Pressure Washdown
A seawater high pressure pump, controlled by a pressure sensor,
supplies the raw water hose connector located in the cockpit.
The pump is located in the engine compartment bilge, aft of
the starboard engine, and activated by the Washdown switch
located at the helm. This switch should be turned to the “ON”
Washdown Connector
Raw Water Pump and Strainer
position just before using the washdown and be turned to the
“OFF” position when the washdown is not in use.
When activated, the pressure switch will automatically control
the pump. As the pressure builds in the washdown hose, the
pump will shut off. When the washdown hose is in use and
the pressure drops, the pump will turn on.
