Marine Head with Holding Tank
Your boat comes equipped with a marine head
(toilet) and waste holding tank system. Be sure
to read the manufacturer’s operation and mainte-
nance 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 intake valve (seacock) is located
under the forward floor hatch in the main
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
under the forward floor hatch in the main
cabin. We advise emptying the holding tank at
every opportunity.
• If you are unable to pump water into the bowl,
the probable cause is debris in the pump dia-
phragm. To remedy this, shut off the seawater
intake valve (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 head, shut off the intake seacock
and pump until the bowl is dry. Remove the drain
plug in the base and pump again to remove all of
the water. Do not fill the bowl with anti-freeze.
The intake seacock should be left closed while
the boat is underway or whenever the boat is left
moored in the water.
Operating the manual flush marine head:
1. Open the head’s seawater intake valve (sea-
cock).
2. Before using the head, pump enough water
into the bowl to wet the sides.
After use, pump until the bowl is thoroughly
cleaned. 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.
