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 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 most of the various accessories.
The optional air conditioner uses an AC sea water supply pump. This is the only AC pump in
the system and it is 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 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. 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 activated by the washdown switch located under
the gunwale on the side of 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 behind the stern access hatch. This should be checked frequently and cleaned
as necessary.
