Blackfin 272 - Chapter 9 DRAINAGE SYSTEM; General; Cockpit & Deck Drainage

9 . 1 Genera l
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 thru-hull ttings are secure and not
leaking.

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 pumpout system. There
are two diaphragm pumps, one for each shbox,
located in the aft systems compartment 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.
Wet Bar Sink
The sink is drained by gravity to a thru-hull tting
in the hull sides.
Livewell
The livewell is drained by gravity to a thru-hull
tting in the hull. The livewell overow drains to
the livewell drain system.
Cup Holders
All cup holders in the helm and cockpit areas drain
by gravity to the cockpit sole.
