9.1 General
All water is drained by gravity to overboard thru-
hull ttings located in the hull above the water
line. It is important to check the drain system
frequently to ensure it is free owing and that the
hoses on the thru-hull ttings are secure and not
leaking. Please review the drainage schematic
to become familiar with the location of the drain
thru-hull ttings.
9.2 Cockpit & Deck Drainage
Cockpit Sole
Your Blackn has four scupper drains located in
the aft system hatch drain rail at the rear of the
cockpit. The scuppers are drained overboard by
thru-hull ttings on each side of the transom. A
ap built into the each thru-hull tting reduces the
surge of seawater through the scupper and into
the cockpit while maneuvering or in rough water.
Water is channeled away from all hatches by a
gutter or drain rail system. The water then drains
overboard through the scupper drain system.
Aft Fishboxes
The shboxes below the rear cockpit sole are
drained overboard by a thru-hull tting and drain
plug in the bottom rear of each box. The drains
are intended to be used when the boat is out of the
water on a trailer, lift or cradle. Always make sure
the plugs are installed before launching the boat.
A pump out system is available as optional equip-
ment. There are two diaphragm pumps, one for
each shbox, located in the aft systems com-
partment that are activated by switches in the
helm switch panel. The pumps drain the boxes
overboard through ttings in the hull sides above
the waterline.
Monitor the water level as the pump drains the
shbox and turn it o immediately when drain-
ing is complete. The pumps could be damaged if
they are allowed to run dry for extended periods.
Prep Station Sink
The sink is drained by gravity to a thru-hull tting
in the hull sides.
