Chapter 6:
RAW WATER SYSTEM
6.1 General
In the raw or sea water systems, each water pump is supplied by a hose connected to a ball
valve and thru hull fitting 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. If the dealer installs an
air conditioner, it uses a 110-volt AC. sea water supply pump. This would be the only 110-
volt AC pump in the system and is automatically activated when the air conditioning or
heating system is in use.
Priming the System
Make sure the thru hull 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.
Notice: 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 in the cockpit below the port 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.
