The Pro X Series Fat Sacs have raised the bar in boat weighting systems. Similar to river rafting material, the new Valmex material is so strong that punctures and abrasions are virtually a thing of the past. Tough strong seams are welded and taped to prevent common failures.
This Pro X Mastercraft X-2 Sac has been made specifically to attach to the automatic factory ballast system that comes on the Mastercraft X-2. To fill this Sac manually with a Tsunami Pump, it will require a W730 fitting (item #101683SP) and a W731 Wally Plug (item #7000007). These fittings are sold separately.
