The macerator pump must be used to
discharge waste overboard. However, DO
NOT use the macerator pump to discharge
waste at a pumping station.
To operate the overboard discharge system:
The discharge valve is located in the engine
compartment labeled HEAD DISCHARGE. To
open, turn the valve so that the handle is parallel
to the ﬂow of the valve. The waste deck plate
cover must be tightened securely for the over-
board discharge system to operate.

2. Turn ON the macerator pump switch which is
located in the head on the switch panel. Allow the
pump to run until the storage tank is empty. The
sound of the pump’s motor load and speed will
change when the tank becomes empty.
B. Head With Overboard Discharge
This option is available on most V series models. The
head toilet operations are the same as the systems
described earlier but an additional line with a “Y” has
been installed for overboard discharge. The waste will
be pumped into the holding tank from the head. The
macera tor pump is installed after the “wye”. Refer to
Figures J5 & J6.
3. Turn the switch off.
4. Turn the discharge valve handle to the closed
position, and secure it. The thru-hull valve must
be closed to prevent water from being forced back
into the system.
