FATSAC Yamaha Jet Boat 24' Custom Ballast Bag - 800 lbs - Grey


Description

The FATSAC C1039 is a custom-fit 800-pound ballast bag designed specifically for 24' Yamaha Jet Boats (compatible with both 24' and 23' 6" models). Built to fit precisely over the Yamaha Swim Deck, this bag delivers serious wake-boosting ballast without the hassle of a generic fit. FATSAC engineers each bag to sit securely and fill completely, eliminating the shifting and sagging that causes damage with ill-fitting options.

Grey in color and constructed from durable PVC with welded cleats, the C1039 comes ready to install with all necessary fittings included. Whether you're chasing a bigger wave for wakeboarding or wakesurfing, this bag is the clean, purpose-built solution for Yamaha owners who want maximum ballast performance from their setup.


Key Features

  • Custom Fit for Yamaha 24' Models: Designed specifically for the 24' Yamaha Swim Deck - fits both 24' and 23' 6" Yamaha Jet Boats.
  • 800 lbs. Total Ballast: Delivers a full 800 pounds of water ballast to dramatically increase wake size for wakeboarding and wakesurfing.
  • Dimensions - 45 x 24 x 34: Precision-sized to fit the Yamaha swim deck area with no trimming or modification needed.
  • All Fittings Included: Comes with fittings W730, 2x W731, and W749 - no hunting for compatible hardware.
  • Compatible with S7090 Pump: Works seamlessly with the FATSAC S7090 pump system to fill and empty (pump sold separately).
  • 4 Welded PVC Cleats: Heavy-duty welded cleats provide secure anchor points for the rope, keeping the bag firmly in place when full.

Why You'll Love It

Yamaha Jet Boat owners know that a generic ballast bag is never truly a perfect fit - and an imperfect fit means shifting, damage, and frustration on the water. The FATSAC C1039 eliminates all of that with a custom-engineered shape that seats correctly on the Yamaha Swim Deck the first time, every time. FATSAC has built its reputation on purpose-built ballast solutions trusted by wakeboard and wakesurf communities across the country.

With 800 pounds of ballast capacity and a complete set of fittings straight out of the box, the C1039 gets you on the water faster and keeps you there longer. The welded PVC cleats and rope-tie design mean the bag stays put even on aggressive wakes, giving you confidence in every run. If you're serious about your Yamaha's wake performance, this is the ballast bag that delivers.

FAQ

Will this bag fit my 23' 6" Yamaha Jet Boat?

Yes! The C1039 is designed to fit both the 24' and 23' 6" Yamaha Jet Boat models. It is specifically shaped for the Yamaha Swim Deck on these boats, so it will seat correctly without modification.

Does the pump come included with this ballast bag?

No, the pump is not included. The C1039 is compatible with the FATSAC S7090 pump system for filling and emptying. You will need to purchase the S7090 separately if you do not already have one.

Do I need to buy a rope separately to secure the bag?

Yes. FATSAC recommends using the M1028 rope to secure the bag through the welded cleats. The rope is sold separately. Proper securing is critical - the rope should be tied tightly around the bag through the cleats, not pulling directly on the handles.

What happens if I only partially fill the bag?

Partially filling the bag can cause it to shift inside the boat, which may result in damage to the bag and potentially to your boat. FATSAC requires the bag to be filled 100% full for safe and proper use. Fill with air first to position the bag, then switch to water and bleed out all remaining air before use.

Will not following installation instructions void my warranty?

Yes. FATSAC is clear that not following the included instructions and installation videos will void the warranty. Be sure to review all instructions before installing and filling the bag to protect your investment.

What fittings are included with the C1039?

The C1039 comes with all necessary fittings: one W730, two W731s, and one W749. No additional hardware is needed for standard installation beyond the separately purchased pump and rope.
