DRAINAGE SYSTEMS
7.1 General
Most water is drained by gravity to overboard
thru-hull fi ttings located in the hull sides above
the waterline. You should check the drain system
frequently to ensure it is free fl owing and that the
hoses on the thru-hull fi ttings are secure and not
leaking.
7.2 Bilge Drainage
There are three bilge pumps, (forward, emer-
gency, and aft,) that are activated automatically
by fl oat switches located next to the pumps.
The bilge pumps are activated both manually by
switches in the helm station and automatically
by fl oat switches located next to the pumps. The
automatic fl oat switches are connected to the
house battery. They are protected by “push to
reset” circuit breakers in the engine compartment
breaker panel and remain activated when the bat-
tery switches are in the “OFF” position and the
batteries are connected. The manual switches are
supplied current when the house battery switch
is activated. They are protected by a breaker in
the helm switch breaker panel.
All bilge pumps pump water out of thru-hulls locat-
ed above the waterline in the starboard side of the
hull. The aft bilge pump and automatic switch are
located near the transom, between the engines,
the emergency bilge pump and automatic switch
are below the step in the engine compartment
and the forward pump and automatic switch are
located in the bilge below aft berth in the cabin.
The manual bilge pump switches should be ac-
tivated briefl y each time the boat is used. This
will ensure that the pumps are operating properly
and increase the service life of the pumps. The
automatic switches should be manually activated
periodically, by turning the test knob on the side of
the switch, to verify operation. This is particularly
important before operating the boat offshore.
The automatic fl oat switch for emergency bilge
pump is mounted above the normal operating
range of the aft bilge pump automatic fl oat switch.
It activates an alarm if the bilge water level rises
above the normal operating range of the bilge
pump automatic switches. The alarm switch is
connected to the house battery and is protected
by the emergency pump “push to reset” breaker
located in the engine compartment breaker panel.
It remains activated when the battery switches
are in the “OFF” position and the batteries are
connected.
When the boat is out of the water, the bilge can
be drained by a thru-hull drain located in the hull
