DRAINAGE SYSTEMS

9.1 General

Most water in the cockpit area is drained by gravity
to the bilge and where it is pumped overboard by
the bilge pump. The rear drain rails for the engine
hatch and rear compartments drain by gravity to
overboard thru-hull fittings in the hull sides. You
should check the drain system frequently to en-
sure it is free flowing and that the hoses on the
thru-hull fittings are secure and not leaking.

9.2 Bilge Drainage

The stern bilge pump is activated both manually,
by a switch in the helm switch panel, and auto-
matically, by a float switch built into the pump.
The automatic float switch remains activated when
the battery switch is in the "OFF" position and the
batteries are connected. The bilge pump pumps
water out of a thru-hull fitting located above the
waterline in the starboard rear hull side.
NOTICE:
See Electrical Systems for additional infor-
mation on bilge pump operation.
When the boat is out of the water the bilge can be
drained by a garboard drain located in the transom
near the bottom of the hull. The plug should be
removed whenever the boat is hauled out of the
water and installed just prior to launching. It is
important to check the drain plug regularly to
make sure it is tight.
CAUTION
A LOOSE DRAIN PLUG WILL ALLOW SEAWATER TO ENTER
THE BILGE AND COULD CAUSE THE BOAT TO SINK. IT IS VERY
IMPORTANT TO CHECK THE DRAIN PLUG FREQUENTLY TO
ENSURE IT IS PROPERLY TIGHTENED.
NOTICE:
See Electrical Systems for additional infor-
mation on bilge pump operation.

NOTICE:
Any oil spilled in the bilge must be thoroughly
removed and properly disposed of before
operating the bilge pump. The discharge of
oil from the bilge is illegal and subject to a
fine.
