Federal regulations prohibit pumping waste overboard within the ter-
ritorial limits of the United States. Check with authorities regarding
specifi c laws and regulations before attempting to pump waste over-
board.
The overboard discharge
feature consists of a hull
bottom mounted sea-
cock, head key switch,
and a macerator (over-
board discharge pump)
to grind up the waste and
deliver it through the sea-
cock overboard.
The seacock is secured in the “closed” position and it must be “opened
before operating the overboard discharge pump. Damage to system
components and/or a potential leak could develop if the sea-
cock is not in the “open” position before activating the pump.
1. Locate the seacock. Remove the locking mechanism from the sea-
cock and turn the valve to the “open” position by aligning the seacock
handle with the valve.
2. The overboard pump key switch is located in the
head. To activate the macerator pump turn the switch
on and completely to the right. At this point the mac-
erator pump will sound starting the pump out process.
It will be required to hold the switch to the right until
the tank is emptied. Once empty return the key switch
to the “off ” position. Have someone monitor the
waste tank level visually during the pump out process.
Avoid running the discharge pump “dry”.
3. Close the seacock by repositioning the seacock handle aligning it
across the hose. Ensure the seacock is closed completely. Relock the
seacock. Failure to relock the seacock within the territorial limits of
the United States could result in boat operator fi nes.
