Raw Water System
Aft Livewell Drain Fitting, Light & Overflow/Fill Valves
8.4 Livewells
Seawater is provided to each livewell by 12 volt cir-
culation pumps. The pumps are designed to carry a
constant flow of water to the livewells. The pumps
do not have a pressure sensor and are activated by
the livewell pump switches in the helm switch panel.
There are also lights in the livewells that are activated
by the livewell lights switch.
Adjustable supply and overflow valves in the side
of the livewell automatically control water flow and
level. Always turn the pump off when a livewell is not
in use. On the rear livewells, the supply and overflow
valves can be used to slightly pressurize the wells
for more lively bait. The forward livewell below the
lounge seat is not intended to be pressurized.
To fill a livewell, insert the drain plug into the fitting
at the bottom of the livewell. Make sure the valves
at the sea chest and the supply valve in the livewell
are open. Then activate the livewell pump. When
the water level reaches the desired level, it will begin
to circulate. Adjust the overflow and supply valves
as necessary to achieve the desired level or pres-
sure and flow.
The sea chest primary intake fitting is equipped
with a high speed pickup that will supply pressur-
ized water to the livewell if the pump should fail and
helps prime the system during normal operation.
To supply water to the livewell using the high speed
pickup, make sure the sea chest intake valves are
open and run the boat at a speed above 15 miles
per hour. Pressurized water from the sea chest will
circulate through the livewell and out the overflow.
To drain the livewell, turn off the livewell pump and
remove the drain plug. When the livewell has com-
pletely drained, use the washdown hose to flush the
livewell and drain of debris.
The livewell supply valves at the sea chest should
be closed whenever the livewell is not in use. This
will prevent water from entering the livewells while
the boat is cruising.
Notice:
Do not use a livewell as a dry storage area
when it is not in use. Seawater could acci-
dently be delivered to the livewell from the
thru-hull fitting and damage equipment stored
there.
