being re-installed in the boat.
Never store batteries
close to heat, spark or flame-producing devices.
Step 3:
Leave the engine box cover propped open about two
inches (2”) to ventilate the engine compartment.
Other Winterization Preparations
Step 1:
Remove the bilge drain plug immediately after taking
the boat out of the water. After a general bow-to-stern
washing, raise the bow of the boat higher than the stern
to allow as much water as possible to drain from the
bilge, while performing other storage preparations.
Step 2:
Thoroughly clean the hull, deck and interior of the boat
as soon as it is removed from the water. Cleaning at this
time is easier because any marine growth is still wet. Be
sure to allow a few days of air drying to prevent mildew
that results from trapped moisture. (See the Cleaning
section of this Manual.)
Step 3:
Apply a coat of wax to the entire surface of the boat. We
suggest MasterCraft Premium Marine Wax for excellent
coverage.
Step 4:
If the boat is equipped with a heater, shower or ballast
bags/tanks, be sure to disconnect the hoses and drain
any remaining water in the lines to avoid freezing. Even
small amounts of water in any of these areas can cause
significant damage upon freezing and such damage is
not covered under the warranty!
Note: Be sure that hoses will not become entangled in the engine
V-belt when the engine turns over or the hose and/or the belt
will be damaged.
Step 5:
Use duct tape to seal the exhaust flaps to prevent dirt
and nesting rodents from entering.
Step 6:
On CSX 265 models equipped with the hot water
heater, any water in the tank must be removed to avoid
the risk of freezing and damage to the tank. The water
pumped into the heater comes from a freshwater hold-
ing tank, and it can be left in the water heater when the
boat is not in use, EXCEPT during extended periods of
storage. As with any part of the boat in which there is
water, it must be removed at the time the boat is win-
terized to avoid freezing that may cause damage to the
boat, the holding tank or the water heater. The water is
removed by running the shower until all the water has
come out or by disconnecting the plumbing fittings in
the forward service bay under the helm seats.
Step 7:
On MariStar 280s and X-80s equipped with heads, clean
the tanks with a mild cleaner or warm soapy water that
will not harm the finish. Avoid all petroleum-based
household cleaners. Store the head dry and clean. Failure
to do so may cause unnecessary odors and damage to the
tanks, and this is not covered under warranty.
On CSX 265 models equipped with heads, thoroughly
flush the system with fresh water. Empty the holding
tank and shut off the water supply to the head, remov-
ing the inlet waterline. Do not remove the brass cap on
the bottom of the valve. Press the flush lever until all
water is drained from the system.
If using anti-freeze in this head, drain the potable water
tank and add freshwater anti-freeze to the potable
water tank. Flush the anti-freeze and water mixture
through the head and into the waste holding tank. Then
empty the holding tank. Never use automotive-type
anti-freeze in this freshwater system.
Step 8:
MasterCraft recommends the battery or batteries be
removed from the boat for winter storage. Batteries
should be fully charged before being stored ina cool,
dry location, protected from the elements and fully re-
charged before being re-installed in the boat.
