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 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 system
(including the heater or, shower, ballast tanks, wash down tanks, cool-
ers, 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 stor-
age 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 ve
(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 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 lter
• Low tack tape

Fuel System Treatment
Step 1: If the boat will be placed in storage with fuel (no alcohol in
the mix) in the tank, ll the tank with fresh fuel and a suf-
cient amount of Sta-Bil® gasoline stabilizer to treat the
entire tank. Follow instructions on the container.
Step 2: If the boat will be placed in storage with fuel that contains
alcohol, the fuel tank should be drained as completely as
possible, the fuel disposed of properly, and Sta-Bil gasoline
stabilizer added to any fuel remaining in the tank. Follow the
directions on the container.
Step 3: Start the engine and operate at idle until the engine reaches
normal operating temperature. (To accomplish this, the boat
must be in the water or attached to a water supply using a
hose and suitable adapter that will allow an uninterrupted
supply of water to the engine. If using a hose and adapter, ad-
just the faucet to avoid over-cooling the engine at low RPM.)
Run the engine for at least fteen (15) minutes and ensure
that the fuel stabilizer enters the engine’s fuel system.
Step 4: Perform the annual maintenance as described in this Own-
er’s Manual.
General Power Package Preparation
Step 1: Lubricate the throttle and shift linkages and cables with
multi-purpose grease.
Step 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 and fully re-charged before being re-installed in
the boat. Never store batteries close to heat, spark or
ame-producing devices.
Step 3: Leave the engine box cover propped open about two inches
(2”) to ventilate the engine compartment.
Other Winterization Preparations
Step 1: 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, while per-
forming other storage preparations.
