Models:
All.
Purpose:
Water inevitably intrudes into any
boat. MasterCraft boats are designed
to expel the water via the bilge system.
When on the water, bilge pumps will ex-
pel water. Bilge pump sensors allow the
system to pump water overboard either
automatically or manually. Because the
bilge is located in the lowest portion of
the boat’s hull, it is not always readily
apparent to individuals on-board wheth-
er there is water in the bilge or not.
To allow operators the opportunity to
manually verify water levels in the bilge, a
center access plate is built into every boat.
The boat has two drain plugs, which
allow water to be drained from the boat
when the boat is OUT of the water. There
is a center T-handle drain and a transom
drain plug. When out of the water, on
a trailer or lift, water can normally be
drained into the bilge system by opening
the center drain.
Boats have sea strainers installed to assist
in keeping debris out of the engine and water
intake systems such as the ballast system.
X-35 and X-55 models that are
equipped with optional Salt Water Pack-
ages also have built-in systems, called
scupper drains, to drain water off the
open deck, sending the water through
the hull and back into the body of water
without going into the bilge.
Location:
The bilge lines and pumps are be-
neath the decks. The center drain loca-
tion will vary slightly by model, but gen-
erally is found close to or adjacent to the
driver’s seat. It will be accessed through
a hatch or access plate, which may be
under marine carpet. A transom drain
plug is on the centerline of the transom.
Sea strainers are located in front of the
engine. Scuppers, where equipped, are
located on the lowest point of the deck,
under the rear seats. Bilge pump-out lo-
cations are on the side of the boat. De-
pending on the model, the pump-out
