Marine Head with Holding Tank
(LX Models Only)
Your boat may come equipped with a marine head and holding tank.
Be sure to follow the manufacturer's operating instructions included
in the boat's owner's packet.
Seawater is used to flush waste from the toilet into the holding tank.
The holding tank is plumbed to a waste fitting on the deck for use at
a dockside pump-out station, or to a macerator pump (optional) so
that waste may be pumped overboard (where regulations permit).
The switch for the macerator is usually located at the helm station.
If at any time you are unable to pump water into the bowl, the proba-
ble cause is debris in the pump diaphragm. To remedy this, shut the
inlet seacock and dismantle the pump. The pump is generally held
together with six screws. The design is simple and the problem will
be obvious when the pump body is split open. To winterize the toilet,
shut off the intake valve and pump until the bowl is dry. Remove the
drain plug in the base and pump again to remove all water. Do not
fill the bowl with antifreeze. The inlet seacock should be left closed
while the boat is underway, or whenever the boat is left moored in
the water.
G r ay Wa te r D r a in S ys t e m
• Gray water (water from sinks and showers) above the water-
line is gravity drained overboard, while gray water below
the waterline is drained into a small holding tank that con-
tains the sump pump and float switch.
• The shower sump pump and holding tank are located under
the entry step. When the holding tank reaches a predeter-
mined level, the tank's float switch automatically activates
the sump pump to empty the tank's gray water overboard.
After the tanks are drained, the sump pumps are designed to
automatically shut off.
• The sump pump should be periodically cleaned of debris
and the float switch tested for proper operation according to
the instructions outlined in the bilge pump and float switch
sections of this supplement.
