Sincewinterstorageisanannualevent,itpresentsanexcellentopportunitytoperform
the annual maintenance at this time, depending upon the amount of usage. Check with
an authorized MasterCraft dealer’s service department regarding the boat’s needs to
determine if this is the 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. Also, if the boat has
been stored in below-freezing temperatures with water inside the bilge or engine cooling
system(includingtheheater,shower,ballasttanks,washdowntanks,coolers,orany
container or area in which water has been located), this condition may result in major
damage from freezing, which would not be covered under the warranty.
 Refertotheengineowner’smanualforguidanceregarding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 (5) months!
Because of the complexity of preparing
a boat for proper winter storage, as well
as the possibility of extreme damage to
the drive train if a preparation error was
made during winterization, MasterCraft
recommends scheduling an appointment with an authorized Master-
Craft dealer’s service department to permit a technician to perform
all winterization procedures.
General Preparation
 Beforestartingyouwillneedthefollowingsupplies:
• Sta-Bil®GasolineStabilizer
• Fuellter
• 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.

will experience some separation of elements and settling during these periods. Of consider-
able concern is that water condensation will occur within the fuel system, and water is an
enemy of good-starting and running engine fuel systems. Therefore, follow this procedure:
