TURN OFF THE bILGE PUMP WHEN THE WATER DECREASES TO A LEVEL THAT PUMP CAN NO LONGER OPERATE.

THE PUMP.
A Tip From Marquis!
A small amount of water always collects in your yachts’s bilge. The water is usually not enough to activate the automatic
switch on the bilge pump. while underway, use the helm switches to manually turn the bilge pumps on, and let the
pumps run for 30 seconds to one minute. when your yacht is on plane, water in the bilge flows to the stern, where the
aft bilge pump is located. The amidships bilge pumps are near the lowest point in the hull.
HULL DRAIN
One hull drain is equipped on the yacht . The drain allows water to drain from the bilges while the yacht is in dry storage . The yacht
and cradle should be positioned to allow water to flow toward the hull drain .
The drain is located in the transom in the deepest POR-
Tion of the hull’s “V .”
The hull drain will drain water only from the bilge area aft of the forward engine bulkhead . If there is a collection of water forward of the
engine room bulkhead, it must be pumped out .
cauTiON
SECURELY TIGHTEN THE DRAIN PLUG INTO THE HULL DRAIN bEFORE LAUNCHING.
A Tip From Marquis!
coat the threads of the hull drain plug with waterproof grease before you install the plug into the hull drain fitting. This
makes it easier to remove the plug at a later date.

pumped to the Gray Water tank . Once the gray water tank is full, the tank can be emptied at dock side with the procedure described

The gray water tank is comprised of two separate tanks connected by a hose . Gravity forces the gray water from one tank to the other
