OPERATION
A high pressure pump, controlled by a pressure sensor, supplies the raw water hose
connector located in the cockpit. The pump is activated by the washdown switch
located in the cockpit. 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 bilge. This should be checked frequently and cleaned
as necessary.
The washdown pump hose connector is located in the cockpit and uses a standard garden hose connection.
ALWAYS TURN THE RAW WATER PUMP SWITCH TO THE “OFF” POSITION WHEN
LEAVING THE BOAT UNATTENDED.
DO NOT RUN THE HIGH PRESSURE PUMP DRY FOR EXTENDED PERIODS AS DAMAGE
TO THE PUMP WILL RESULT.
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 switch to the “ON” position. Run the pump until all of the
air is purged from the system and then turn the switch to the "OFF" position. Turn the livewell switch to
the “ON” position. Run the pump until all of the air is purged from the system and then turn the switch to
the “OFF” position. Closing the thru-hull ball valves before the boat is hauled from the water will help to
eliminate air locks in raw water systems.
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.
5.3 Air Conditioning Pump (Optional)
The air conditioner is self-contained and sea water cooled. An AC centrifugal raw water pump supplies sea
water that cools the condensing unit as it circulates through the system and is discharged overboard. The pump
is located in the machinery space and is activated whenever AC current is available and the air conditioning
system is operating.
Sea water is supplied to the pump from a thru-hull fitting located in the hull near the pump. A sea strainer
between the pump and thru-hull fitting protects the system from contaminants that could damage the pump
or the air conditioning system. Make sure the sea water pump receives adequate sea water by periodically
cleaning the sea strainer basket.
