10.2.3 High Water Bilge Pump
The optional high water bilge pump is a redundant sys-
tem for additional protection on water accumulation within
the boat. As noted above, if a high water condition exists
and the optional high water bilge pump is installed (Fig.
10.2), the pump will be activated in conjunction with the
alarm.
It is located in the main bilge and accessed through the
forward center floor panel in the main cabin. It has a
pumping capacity of 66 GPM and functions to remove
water from the bilges in the event the main bilge pump
is overwhelmed or becomes inoperable. The pump will
discharge waste through a starboard thru-hull.
10.2.3 Manual Bilge Pump
The manual bilge pump (Fig. 10.4), located in the port
forward cockpit, is also a redundant system for addi-
tional protection. The pump includes a manual handle
to be inserted into the pump mechanism where the up
and down motion on the handle will begin discharging
water out the thru-hull mounted on the port sidewall of
the steering cavity. Pumping capacity will depend on
the speed of the pump action. The actual pump can be
access through the port seat lid. The manual handle is
stored on the underside of the port seat lid. The receiver
for the manual handle is mounted to the port cockpit seat
face (includes a flip-down cover) (Fig. 10.5). The hose
intake is located in the main bilge (Fig. 10.2)

10.2.4 Grey Water Collection Box/Pump System
The collection box/pump system (Fig. 10.6) serves to
automatically discharge grey water originating from the
vanity sink, shower and condensation from the optional
air conditioning system which all drain into the collec-
tion box. The unit is located in the main cabin and is
accessed through the center aft floor panel.
No maintenance is required on the pump itself. However,
the system includes a filter to collect larger waste materi-
als. Periodically service the filter by removing the lid for
access. Remove the filter and clean. Replace the filter
and lid when done.
