2016 OWNERS MANUAL / 0363
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, Master-
Craft recommends scheduling an appointment with an authorized
MasterCraft 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 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.
Boats that are going to be stored for extended periods (more than
two [2] weeks) or winterized should have attention for the fuel sys-
tem. Even TOP TIER gasolines will experience some separation
Storage or winter lay-up requires special preparation to prevent
damage to the boat. Since winter storage is an annual event, it pres-
ents 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-freez-
ing temperatures with water inside the bilge or engine cooling sys-
tem (including 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 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.
