DRAINAGE SYSTEMS
9.1 General
All water is drained by gravity to overboard thru-
hull fittings located in the hull or to the bilge. It
is important to check the drain system frequently
to ensure it is free flowing and that the hoses on
the thru-hull fittings are secure and not leaking.
9.2 Cockpit Scupper Drains
Your Crevalle has two scupper drains located in the
rear of the cockpit. External check valves reduce
the surge of seawater through the scuppers and
into the cockpit while maneuvering or in rough
water. The check valves should be inspected
periodically to make sure they are free, clear of
debris and not damaged.
A removable drain plug near the cockpit scuppers
in the cooler recess below the bench seat allows
the cockpit to be drained to the bilge if the scup-
per drains become clogged. Make sure the drain
plug is installed and tight when draining operations
are complete.
Water is channeled away from all hatches by a
gutter or drain rail system. The water then drains
overboard through the scupper drain system or
thru-hull fittings below the hatch drain rail.
9.3 T-Top/ Spotting Tower Drains
There is a hole drilled in the leg bases on the
frame to prevent water from being trapped within
the legs. Additional drain holes are drilled in the
tubing to drain other areas as required.
Always make sure the leg drain holes are clear
when the boat is laid up for the winter. Water
trapped inside the legs could freeze and cause
the legs to split.
