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 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 vari-
ous accessories.
The air conditioners and bait freezer use 240-volt AC sea wa
-
ter supply pumps. These are the only 240-volt AC pumps in
the system and they are automatically activated when the air
conditioning or heating 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 Salt Water Pump breaker and the Raw Water
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 to the “ON” position. Run the
pump until all of the air is purged from the system and then
turn the breaker to the “OFF” position.
The intake for the bait freezer and 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 al
-
low 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 saltwater high pressure pump, controlled by a pressure
sensor, supplies the raw water hose connector located in the
cockpit. The pump is activated by washdown switch located
in the switch panel near the flybridge ladder. This switch should
be turned to the “ON” 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.
The raw water washdown system is equipped with a sea strainer
on the intake side of the pump located in the stern bilge. This
should be checked frequently and cleaned as necessary.
The Washdown Pump Connector
A quick-release raw water washdown hose connector is located
on the port side of the cockpit below the gunnel. It is identi
