The holding tank is located in the bilge below
the cockpit oor or in the aft storage compart-
ment. The uid level in the holding tank must be
monitored frequently to ensure the tank does not
become overlled. When full, the tank must either
be pumped out by an approved waste dumping
station through the waste deck tting or the op-
tional overboard discharge pump.
The uid level is monitored by LED lights in the
toilet control panel. When the tank is full, the red
LED light on the panel will be lit, indicating that
ushing is not recommended.
To pump out the holding tank with the overboard
waste discharge system, open the valve at the
discharge thru-hull tting in the aft storage com-
partment bilge and activate the momentary switch
in the Overboard Discharge switch panel. Moni-
tor the uid level closely as the tank is pumped.
Release the switch and to turn o the discharge
pump when pumping is complete, then close the
ball valve at the thru-hull tting.
Notice:
Monitor the pumping operation as the over-
board discharge drains the holding tank. Be
preparedtoturnthepumpoimmediately
when draining is complete.
Notice:
In order to comply with current State,
Federal and Coast Guard regulations, the
OverboardDischargeValvemustbeoand
secured with a lock or wire cable tie strap
whenever the boat is operating in areas in
which the discharge of sewage is prohibited.

IN MANY AREAS IT IS ILLEGAL TO PUMP HEAD WASTE

Head System Maintenance
The head should be cleaned and inspected for
leaks regularly.
The holding tank should be pumped out and
ushed as needed. Periodically add chemical
to the holding tank to help control odor and to
chemically break down the waste. Refer to the
head manufacturer owner’s manual for additional
operating and maintenance information.
The vent hose for the holding tank is equipped with
a charcoal lter to reduce odor from the holding
tank. The lter should be changed once a year or
if the holding tank has become overlled, which
will plug the lter and could cause damage to the
waste system.
Notice:
The head system must be properly winter-
ized before winter lay-up. Please refer to
the Seasonal Maintenance chapter and the
manufacturer owner’s manual for winter-
izing instructions.
