MasterCraft X Series Rear Ballast Upgrade Adapter Assembly (2006–2013)

Drop-in adapter assembly that connects an auxiliary WakeBallast ballast bag to the factory rear hard tank on 2006–2013 MasterCraft X-55 models. Replaces the factory vent/overflow hose with a preconfigured hose assembly that restores factory venting while adding fill/drain and vent/overflow connections for your ballast bag.

Each assembly arrives fully assembled and labeled — the "Through-Hull Fitting" end connects to the hull vent fitting, the opposite end connects to the factory hard tank vent port. Quick-connect fittings with red locking rings make bag hookup fast and tool-free. Install time is 15–30 minutes per side with basic hand tools (flathead screwdriver, 5/16" socket, ratchet).

No cutting, no drilling, no permanent modifications. The factory hard tank stays in place and continues to function. You're just adding capacity on top of it.
