FATSAC Yamaha 27' Swim Deck Ballast Bag - 1,200 lb - Grey


Description

The FATSAC Yamaha 27' Model Swim Deck Bag (C1326) is a precision-fit ballast solution engineered specifically for Yamaha 27' and 26' 6" swim deck boats. Delivering 1,200 lbs. of total ballast, this bag lets you dial in the perfect wake shape for wakeboarding, wakesurfing, or any towsport pursuit behind your Yamaha jet boat. Built from durable PVC construction with 4 welded-on PVC cleats, the bag is designed to stay firmly in place throughout even the most aggressive sessions on the water.

All necessary fittings are included right out of the box, so setup is straightforward and hassle-free. FATSAC has built a reputation among serious towsport enthusiasts for manufacturing ballast bags that fit precisely, hold up to seasons of hard use, and produce consistent, repeatable wake performance. If you're serious about getting the most out of your Yamaha jet boat, this is the ballast bag built for it.


Key Features

  • Boat-Specific Fit: Custom-designed to fit the 27' Yamaha Swim Deck, compatible with 27' and 26' 6" Yamaha jet boats.
  • 1,200 lb Ballast Capacity: Adds serious weight for improved wake size and shape for wakeboarding and wakesurfing.
  • All Fittings Included: Comes with fittings W730, 2x W731, and W749 - ready to install right out of the box.
  • 4 Welded-On PVC Cleats: Provides secure anchor points for rope tie-down on both top and bottom of the bag.
  • Compatible with S7090 Pump: Works with the FATSAC S7090 ballast pump to fill and empty the bag (pump sold separately).
  • Durable PVC Construction: Built for long-term use on the water with tough, welded PVC materials.

FAQ

Will this bag fit my Yamaha jet boat?

The C1326 is specifically designed to fit the Yamaha 27' Swim Deck, and it is also compatible with 26' 6" Yamaha jet boats. If you are unsure about your exact model, check your boat's swim deck dimensions before ordering, or reach out to us at service@omahasportsandgames.com and we'll help you confirm fitment.

Do I need to buy a pump separately?

Yes - the FATSAC S7090 ballast pump is compatible with this bag but is sold separately. All fittings needed to connect the pump to the bag are included with the C1326. We recommend confirming you have the S7090 or a compatible pump before your first use.

How do I properly fill and secure the ballast bag?

Start by filling the bag with air to properly seat it on the swim deck. Once positioned, use your ballast pump to fill the bag with water. Use the air release valve to bleed out all remaining air as you fill - the bag must be 100% full with no air left inside. Secure the bag using a 12-foot or longer rope threaded through the welded PVC cleats on both the top and bottom of the bag. The handles are rope guides only - never put direct pulling force on the handles or cleats themselves.

Can I partially fill the bag to get less ballast?

No - the bag must always be filled 100% full. Partially filling the bag can cause it to shift during use, which can damage the bag and void the warranty. If you want less ballast, FATSAC offers a range of other bag sizes that may better match your needs.

What rope do you recommend for securing the bag?

FATSAC recommends using the M1028 Heavy Duty Marine Dock Line (sold separately) to secure the ballast bag. You need a rope that is at least 12 feet long. The rope should be tied tightly around the bag and threaded through the cleats - not putting any pull on the handles themselves.
