RAW WATER SYSTEM
5.1 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.
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.
5.2 High Pressure Washdown (Optional)
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 in the helm or the rear 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.
