Raw Water System
baitwell pump priming procedure for all other
pumps connected to the sea chest.
The sea chest water intake fittings are equipped with
scoops that will supply pressurized water to the sea
chest and help prime the system while the boat is
underway during normal operation. If a pump runs
but will not prime, make sure the pump supply
valve is open. If the pump still won’t prime, it
may be air locked. Make sure the sea chest intake
valves and the valve for the pump intake hose are
open and run the boat at or above 15 MPH. Wa-
ter pressure from the sea chest will usually force
the trapped air through the pump and allow it to
prime. If this procedure doesn’t work, contact
your Scout dealer.
Closing the sea chest intake thru-hull valves be-
fore the boat is hauled from the water will help
to eliminate air locks in raw water systems. The
valves should also be closed whenever you leave
the boat in the water unattended.
Notice:
It may be necessary to reprime the raw wa-
ter system if it is not used for an extended
period and at the time of launching.
8.2 Raw Water System Operation
The high pressure pump that supplies the raw
water washdown hose is located on the star-
board side of the aft systems compartment. It
is controlled by a pressure sensitive switch and
activated with the CZone control feature. When
activated, the pressure switch will automatically
control the pump.
As the pressure builds in the system, the pump
will shut off. When the system is in use and the
pressure drops, the pump will turn on.
Whenever the boat is left unattended, the pres-
sure pump should be turned off.
Washdown Hose Connectors
The raw water washdown hose is located on the
starboard side of the hardtop above the leaning
post. The hose is equipped with an automatic
retracting reel.
To use a washdown hose, make sure the raw water
pressure pump is activated. Pull the nozzle and
hose out of the fitting to the desired length. When
washdown operations are complete, turn OFF the

Or Optional SeaKeeper Cooling Pump
Raw Water Washdown Hose
nozzle and pull the hose out slightly to release the
reel lock. Keep steady pressure on the hose and
allow it to slowly retract until the nozzle seats in
the recess.
CAUTION
DO NOT ALLOW THE WATER PUMP TO RUN DRY. THE
PUMP WORKS ON DEMAND AND WILL NOT SHUT OFF
AUTOMATICALLY IF NO WATER IS AVAILABLE. THIS CAN
RESULT IN DAMAGE TO THE PUMP. ALWAYS TURN THE RAW
WATER PUMP OFF WITH THE CZONE CONTROL FEATURE WHEN
THE SYSTEM IS NOT IN USE.
