Raw Water System
is used to regulate the ow of oxygen in the water
when the recirculating feature is activated.
The raw water manifold intake is equipped with
a high speed pickup that will supply water to the
either livewell if the supply pump should fail and
helps prime the system during normal operation.
To supply water to either well using the high speed
pickup, make sure the ball valves on the manifold
are open and run the boat at a speed above 15
miles per hour. Water will circulate through the
well and out the overow.
To drain the wells, turn off the pumps and remove
the plug in the drain ttings. When the well has
completely drained, use the washdown hose to
ush the well and drain of debris. There is a hook
on the side of each well for the drain plug when
the well is not in use.
The ball valve at the pumps should be closed
whenever the wells are not in use. This will pre-
vent water from entering the well while the boat
is cruising.
Notice:
Do not use the livewells as a dry storage
area when they are not in use. Seawater
could accidently be delivered to the well from
the thru-hull tting and damage equipment
stored there.
A RUPTURED RAW WATER INTAKE OR PRESSURE LINE COULD
CAUSE THE BOAT TO TAKE ON WATER. ALWAYS TURN THE
RAW WATER SYSTEMS OFF AND CLOSE THE THRU-VALVES
WHEN LEAVING THE BOAT UNATTENDED.
8.4 Air Conditioning Pump
The air conditioning unit is self-contained and
seawater cooled. A 120 volt AC centrifugal pump
supplies seawater that cools the condensing unit
as it circulates through the system and is dis-
charged overboard. The seawater pump for the air
conditioner is located in the mechanical systems
compartment. It must be activated by the HVAC
Pump circuit breaker in the cabin AC electrical
panel whenever the air conditioner is running.
Seawater is supplied to the pump by a ball valve
and hose connected to the raw water manifold. A
sea strainer between the pump and ball valve on
the manifold protects the system from contami-
nants that could damage the pump or the air con-
ditioning system. Make sure the pump receives
adequate seawater by periodically cleaning the
sea strainer basket. Refer to Raw Water System
Maintenance in this chapter for information on
cleaning the sea strainer.
You should refer to the air conditioner owner’s
manual for more information on the operation and
maintenance of the seawater pump.
8.5 Generator Raw Water Supply
The generator engine uses a closed cooling sys-
tem with a seawater-cooled heat exchanger. The
seawater circulates through the heat exchanger
and is expelled through the generator exhaust sys-
tem, cooling it as well. It includes a strainer that
prevents debris in the seawater from entering the
cooling pump. The strainer is located in the stern
bilge and supplied seawater by a dedicated thru-
hull tting and seacock valve near the strainer.
It is important to check and clean the strainer
