Even small amounts of water in any of these areas can cause
significant damage upon freezing. Such damage is not covered
under warranty.
Be sure that disconnected hoses will not become entangled in the
engine belt when the engine turns over. Failure to do so may result
in damage to the engine and/or critical boat systems.
7. For boats equipped with an engine flush kit you must winterize the
engine flush fitting mounted to the transom of the boat:
• Remove the boat from the water.
• Drain the engine according to the Ilmor Engine Owner’s Manual
included with the Owner’s Manual Information Packet.
WINTERIZATION PREPARATIONS
1. Lubricate the throttle and shift linkages and cables with multi-
purpose grease.
2. MasterCraft recommends that batteries be removed from the boat
for winter storage. Batteries should be fully charged before being
stored in a cool, dry location, protected from the elements. Fully
recharge the batteries before re-installation in the boat. Never
store batteries close to heat, spark or flame-producing devices.
3. 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.
4. Thoroughly clean the hull, deck and interior of the boat as soon
as it is removed from the water. Cleaning while the boat is still
wet is recommended rather than waiting until the boat is taken
out of storage. Any marine growth in or on the hull will be wet and
easier to remove. Be sure to leave the boat’s storage and engine
compartments opened up so they can properly air dry and prevent
mildew from trapped moisture. (See the Cleaning section of this
Owner’s Manual.)
5. Apply a coat of wax to the entire surface of the boat.
MasterCraft Premium Marine Wax provides excellent coverage and
is recommended.
6. If the boat is equipped with a heater or ballast bags, be sure to
disconnect the hoses (ballast hoses and heater circulation pump
hoses) and drain any remaining water in the lines to avoid freezing.
