WakeBallast 2003-06 MasterCraft X9 - Rear Seat - 345lbs

More weight in the rear means a bigger wake and a better surf wave. This bag drops directly into your factory ballast system — no custom plumbing, no rewiring. It fills and drains automatically using your existing dash switches, just like stock, but with significantly more capacity.

Built in Chandler, Arizona and backed by a 2-year warranty. Most orders ship within 48–72 hours.

Each bag comes with male quick release 1 1/8” fittings to connect to your existing female quick release hose ends. If your boat requires different fittings, browse our fittings here.
