Fuel systems on all boats MUST be
properly prepared for storage periods
exceeding two (2) weeks, as outlined in
this Owner’s Manual. Failure to do so will
void the warranty.
General Power Package Preparation

Step 2: MasterCraft recommends that batteries be removed from the boat for winter
storage.Batteriesshouldbefullychargedbeforebeingstoredinacool,dryloca-
tion, protected from the elements and fully re-charged before being re-installed
in the boat. Never store batteries close to heat, spark or flame-producing
devices.

Other Winterization Preparations

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 perform-
ing other storage preparations.
Step 2: Thoroughly clean the hull, deck and interior of the boat as soon as it is re-
moved from the water. Cleaning at this time is easier because any marine

thatresultsfromtrappedmoisture.(SeetheCleaningsectionofthisManual.)
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 freez-
ing. 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.

soapy water that will not harm the finish. Avoid all petroleum-based household

odors and damage to the tanks, and this is not covered under warranty. 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 fresh-
water system.
Step 7: If the tower will be lowered
during storage, be certain
that the tower does not rest
on the boat upholstery or on
any support that rests on
the upholstery. The tower
