Factory ballast bags often fall short of building a competition-ready surf curl, making the flagship FatSac Jumbo V-Drive Wake Surf Ballast Bag an essential heavyweight upgrade for long hulls. FatSac engineered this maximum capacity sac to fit cleanly inside the rear engine locker compartments of V-drive boats 23 feet and longer. Pushing an incredible 1100 lbs of water weight into a single compartment forces the transom deep into the water column. The massive rear displacement generates an unyielding edge hold during wakeboard launches while expanding your wakesurf pocket. Wave faces grow massive.

This industrial ballast skin uses a proprietary, layered UV-stabilized polyvinyl ballast material paired with high-frequency welded seams that never split from sudden hull slams. The heavy-duty construction handles extreme internal hydraulic forces, acting as a direct OEM upgrade for factory systems in Supra, Moomba, Malibu, and Axis boats. Captains configuring automated drainage lines frequently match these high-volume ports with hardware from our boat wakeboard package sets inventory to secure fast pumping. A bottom drain port speeds up packing.

Maximum V-Drive Rear Ballast & Pro Wakesurf Wave Optimization

This 1100 lbs jumbo locker bag functions as the ultimate weapon for heavy V-drive boats that require serious rear-end displacement to shape a steep wave face. Pushing the transom down creates an intense energy pocket that lets surfers drop the rope safely.

Our boat crew integrated this 1100 lbs jumbo bag into a standard 24-foot V-drive engine locker. The high-volume bottom drain is highly effective, evacuating the full 132-gallon chamber quickly without leaving pooling water inside the fabric folds. The wave transformation is staggering, throwing out a massive, clean surf zone with an intense lip.

Why Choose FatSac Jumbo V-Drive Wake Surf Ballast Bag

Standard thin water bladders melt, crack, or rot when exposed to hot engine bay temperatures and raw fuel fumes, causing massive interior leaks that short out bilge electronics. The FatSac Jumbo bag prevents this expensive damage by wrapping your ballast inside a chemical-resistant, heavy-duty vinyl shell, protecting your boat plumbing budget.

Factory Warranty & Professional Care Guidelines

FatSac backs this flagship heavyweight sac with an official 1 Year Limited Manufacturer Warranty covering material and seam defects. To ensure optimal performance from the welded valve ports, hand-tighten all quick-twist fittings before launching the boat. Dry the vinyl completely before long-term winter storage.
