2023 OWNER’S MANUAL / 384
Winterization is a complex process that may result in damage
to the engine, drive train and other components if improperly
performed. MasterCraft recommends winterization by an authorized
MasterCraft dealer.
GENERAL PREPARATION
Before starting you will need the following supplies:
• Sta-Bil® Gasoline Stabilizer
• Fuel filter
• Low tack tape
FUEL SYSTEM TREATMENT
This preparation needs to be done prior to removing water from the
engine, if that will be part of the process.
Storage or winter lay-up requires special preparation to prevent
damage to the boat. Since winter storage is an annual event, it
presents an excellent opportunity to perform annual maintenance.
Check with an authorized MasterCraft dealer’s service
department regarding your boat’s needs to determine if this is an
appropriate time for annual service.
Without proper preparation, storage for long periods of time (at
any time of the year) may cause harm to various components
of the boat and drive train. If the boat has been stored in below-
freezing temperatures with water inside the bilge or engine
cooling system it may result in major freezing damage to any of
the following: the heater, shower, ballast tanks, wash down tanks,
coolers, bilge and ballast pumps; or any container or area in which
water has been located. This type of damage is not covered under
warranty.
Refer to the Ilmor Engine Owner’s Manual, included in the New
Owner Information Package for guidance regarding the storage
and winterization of the engine, transmission and components
of the drive train. The following procedures will help avoid most
potential types of damage during storage for a period not to
exceed five months.
