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

1 1/8" quick release

The most common size across the industry. Used on most Malibu, Supra, Tige, Centurion, Axis, Nautique, and Mastercraft boats from roughly 2010 to 2024. If you're unsure, this is the safe bet.

3/4" quick release

Found on some older Mastercraft models (early-to-mid 2000s) and select other boats with smaller ballast plumbing. If your existing hose ends look noticeably smaller than a garden hose fitting, you likely have 3/4".

1.5" quick release

Newer 2025+ model year boats are moving to larger 1.5" fittings for faster fill rates. If you have a 2025 or newer boat, check your existing fittings before ordering.
