RAW WATER SYSTEM
8.1 General
In the raw or seawater systems, the baitwell sea-
water pump is mounted to a seacock on a thru-hull
tting located in the aft systems compartment
bilge. The water system pressure pump or other
cooling pumps are connected to an auxiliary sup-
ply tting at the base of the baitwell pump or a
separate seacock. Always make sure all valves are
open before attempting to operate any component
of the raw water system.
Priming the System
Make sure the seacock valves are open and the
Raw Water switch in the helm switch panel or touch
screen display is on. Run the pressure pump by
turning on the raw water washdown hose nozzle
until all of the air is purged from the system, then
turn the nozzle o. Turn the baitwell switch on and
run the baitwell pump until all of the air is purged
from the system, then turn the pump o.
The intake for the baitwell centrifugal pump is
equipped with a scoop and ball valve. If a pump
runs but will not prime, make sure the valve is
open. If the pump still won’t prime, it may be
air locked. Make sure the valve is open and run
the boat at or above 15 M.P.H. Water pressure
from the scoop will force the trapped air through
the pump and allow it to prime. If this procedure
doesn’t work, contact your dealer.
Closing the thru-hull valves before the boat is
hauled from the water will help to eliminate air
locks in the raw water system. The valves should
also be closed whenever you leave the boat unat-
tended.
Notice:
It may be necessary to reprime the raw water
system if it is not used for an extended period
and at the time of launching.
8.2 Raw Water System Operation
A high pressure pump, controlled by a pressure
sensor, is activated by the Raw Water switch.
When activated, the pressure switch will automati-
cally control the pump that supplies the raw water
washdown hose.
Chapter 8:
As the pressure builds in the system, the pump
will shut o. When the system is in use and the
pressure drops, the pump will turn on. The water
pump is equipped with a strainer on the intake
side of the pump. The strainer should be checked
frequently and cleaned as necessary.
Whenever the boat is left unattended, the Raw
Water switch should be turned o.
