FatSac C1046 Yamaha Jet Boat Custom 21 ft 725 lb Ballast Bag with Fittings - Grey

The FatSac C1046 is a semi-custom transom ballast bag engineered specifically for 21-foot Yamaha Jet Boats. Designed to tie down securely to the swim platform step, this 725-pound ballast bag adds significant weight to the rear of the vessel to help create a larger, more surfable wake.

Key Features:

• 725 lbs of ballast capacity — dramatically improves wake size for wakesurfing and wakeboarding
• Custom fit for 21 ft Yamaha Jet Boats (2006 to current model years)
• Dimensions: 35"L x 26"W x 32.5"H for a precise fit on the swim deck
• 4 welded-on PVC grab handles for easy rope or strap securing to the platform (tie-downs not included)
• 2 fill/vent ports and 2 drain ports for efficient filling and emptying
• Compatible with the FatSac Supa Tsunami Pump (W709-SUPA) for fast fill and drain times
• Color: Grey

Included Fittings:

• 1x W730 fitting (for use with Supa Tsunami Pump)
• 2x W731 fittings
• 1x W749 fitting/cap

Usage Tips: Before filling with water, inflate the bag with air to establish proper positioning and secure tie-downs. Once the bag is secured, fill with water and bleed the air via the top valve, then continue filling until the bag is 100% full to prevent movement during use.

Note: Grab handles are guides for ropes or straps only — they are not rated to support the full weight of the filled bag. Rope guides M1028 are available separately. 1-Year Manufacturer Warranty.
