Marine Head With Holding Tank (If Equipped)

Your boat may be equipped with a marine head
(toilet) and waste holding tank system. Be sure to
read the manufacturer's manual (included in your
boat's owner's packet).
• The marine head installed on your boat uses
seawater to flush waste from the toilet. The
seawater pickup valve (seacock) is located
under the entry steps in the cabin.
• Waste is routed directly from the head to the
holding tank.
• The holding tank is plumbed to a fitting on the
deck for dockside pump-out.
• You can determine the content level of the
holding tank by looking at the tank located on
the starboard side of the bilge. Empty the
holding tank at every opportunity.
If you are unable to pump water into the bowl, the
probable cause is debris in the pump diaphragm.
To remedy this:
1. Shut Off the seawater pickup valve (seacock).
2. 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).
3. Reassemble the pump.
4. Open the seacock.

Using The Marine Head

1. Open the head's seawater pickup
valve (seacock).
2. Before using the head, pump enough water
into the bowl to wet the sides.
3. After use, pump until the bowl is clean. Continue pumping a few more times to clean the lines.
If excess waste causes the water to rise in the bowl, stop pumping until the water recedes.
Close the pickup seacock before getting underway and leave it closed while the boat is underway or whenever
the boat is left moored in the water.

Winterizing The Head

1. Shut Off the pickup seacock and pump the head until the bowl is dry.
2. Remove the drain plug in the base and pump again to remove all of the water.
• Do not fill the bowl with anti-freeze.
• Close the pickup seacock while the boat is underway or whenever the boat is left moored in the water.
