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 er-
ror was made during winterization, MasterCraft recommends scheduling an
appointment with an authorized MasterCraft dealer’s service department to
permit a technician to perform all winterization procedures.
Storage or winter lay-up requires special preparation to prevent damage to the boat. Since winter storage is an annual event, it presents an ex -
cellent 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 or, 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.
Storage and
Winterization
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
forty-five [45] to sixty [60] days) or winterized should have attention for
the fuel system. Even TOP TIER gasolines will experience some separation
of elements and settling during these periods. Of considerable 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:
• The fuel tank should be ninety-to-ninety-five percent (90-95%) full
of TOP TIER gasoline. This allows for minimal room in which air can
oxygenate the fuel during diurnal cycles (daily periods of expansion/
contraction of gasoline vapors and air as a result of temperature
changes). As temperatures rise in the tank, the pressure also rises,
pushing out gasoline vapor-and-air mixtures. When the temperature
falls, pressure lowers and the system will seek to draw fresh air and
water vapor (depending on the humidity level) into the tank. Fresh air
is replaced with “light ends,” which are low-boiling components that
vaporize at ambient temperatures. Light ends are required during
cold starts to vaporize the fuel. Since the daily diurnal cycles elimi -
nate the light ends, a nearly full tank helps to minimize the air volume
entering the system.
• Add a biocide additive in the fuel tank to limit microbial growth in
gasoline. Follow the directions provided by the stabilizer’s manu -
facturer.
• Add a fuel stabilizer, such as Sta-Bil
®
, to the fuel tank. Follow the
directions provided by the stabilizer’s manufacturer.
• Run the engine for at least fifteen (15) minutes while in a body of
water. This allows for the circulation of the additives throughout
the fuel system.
• If possible during storage, the tank vents should be sealed. If the
vent is sealed, the tank must NOT be completely filled. A ninety-
to-ninety-five percent (90-95%) filled tank allows room for expan -
sion, which will be required at certain times when temperatures in-
crease. The hydrocarbons in gasoline react with naturally occurring
oxygen and create a by-product known as “gum.” The substance,
as the name infers, plugs up fuel filters and injectors. Sealing the
tank helps reduce gumming by significantly limiting the amount
of oxygen available for interaction with the hydrocarbons.
Completely filling the fuel tank prior to storage and then
sealing the fuel tank vent does not allow room for neces-
sary expansion. This can result, in extreme conditions, in
fuel tank rupture. Such release of fuel into the boat and
potentially into the storage area could result in substantial
damage to the boat and contact with any spark (such as a
flame-producing pilot light in a heater) could also result in
property damage and serious injury or death.
It is desirable to keep the fuel’s temperature below 80 F. (26 C.)
The gumming will increase as temperatures increase.
Note that fuel stabilizers work ONLY in fresh gasoline. Stabilizers
will not cure oxygenated gasoline. Adding a stabilizer when the boat is
being prepared for outings after storage will NOT clean the gumming
