RAW WATER SYSTEM
6.1 General
In the raw or sea water systems, all water pumps are supplied by a hose connected to a ball valve
located in the bilge compartment. 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 the various accessories.
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 off. Turn the livewell
switch to the “ON” position and 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.
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 located in the stern bilge below the sink and is
activated by the washdown switch located below the starboard gunnel. 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 located on the intake side of the
pump. This should be checked frequently and cleaned as necessary.
