5. Because the NXT Series uses a dierent style ballast system than
X and XT series models, the antifreeze will stay in the ballast system
during storage rather than being immediately pumped out.
Upon reactivating the boat the first time after storage, run the ballast
system to pump out the antifreeze (the engine must be on and the
boat must be in the water).
The original bridge connector in the ballast system must be
reinstalled if the optional plug-in bags are removed from the
system. Failure to do so will result in any water in the ballast
system evacuating into the storage compartment, potentially
flooding the storage compartments. This could sink the boat,
resulting in serious injury or death.
REACTIVATING THE BOAT AFTER
STORAGE
Step 1
Remove duct tape from exhaust flaps.
Step 2
Fully charge the battery(ies) and install them in the boat, following
all safety precautions associated with changing batteries.
Often, batteries that have been stored over winter will require
recharging. Only an authorized battery charger should be used to
charge the battery(ies) in MasterCraft boats. Use only a three-stage
or more battery charger. It is important that the operator never
turn a battery charger immediately to “start,” as the sudden jolt of
voltage may cause damage to the electrical system, particularly the
control modules for the ballast system. Regardless of the time of
year, care should always be used when charging a battery(ies).
Step 3
Follow all instructions for reactivating the engine and drive train as
detailed in the Ilmor Marine Engine Owner’s Manual.
