FATSAC 21 ft Yamaha 725 lb Jet Boat Ballast Bag

This FATSAC custom ballast bag is intended for compatible 21 ft Yamaha jet boats from model year 2017 onward. It carries up to 725 lb of water ballast for adjusting stern weight. The gray bag rests in the rear swim-platform area used for wake-surfing configurations. Earlier 21 ft Yamaha models are not included in the stated compatibility.

Four built-in handles offer points for keeping the bag secured on the platform step. Tie-downs are not part of the package and must be selected separately. The supplied plug and W730 fitting connect with the FATSAC Supa Tsunami pump system.

The valve/cap package contains two W731 assemblies, one W749 and one W730. One bag is included; the pump is not included. Check the Yamaha model year and rear-platform arrangement before installing the ballast bag. Browse more general boat outfitting.
