Maximize the factory ballast system in your 2002-2008 Supra or Moomba boat for the best wake.


Quickly and easily upgrade the factory ballast bag in your Supra or Moomba wakeboard boat with our upgrade hardware kit.

This kit is designed for 2002-2008 Supra and Moomba wakeboard boats equipped with the Gravity III wakeboard ballast system from the factory. Determine the perfect weigh for your boat with the option to add between 750 and 1400 pound ballast. Because any upgraded bag will be taller than the factory bag, we include a prefabricated fill hose extension that will quick connect to the factory hose. The extension is made with the same hose and fittings as the factory connection to simplify the install.

Quick Connect DetailPlug and Play Design The secret to our BagBuster upgrade is the pre-fabricated extension hose that connects directly to the Flow-Rite Quick Connect Fitting currently in your boat. That means the entire installation is completely plug-and-play, takes less than two minutes, and requires no modifications to your boat.

Together with the Flow-Rite Quick connectors already installed in the new ballast bag you'll be ready to ride in a matter of minutes, and you can return everything to stock just as fast if you decide you want to sell the boat.

Bag SizeApplication
No BagChose this option if you already have a Fly High Pro X Series ballast bag
565 lbsSuitable for use in all 2002-2008 Supra and Moomba v-drive boats
750 lbsSuitable for use in 2002-2008 Moomba Outback V, LSV and XLV boats and 2002-2008 Supra 20V, 21V, 22V and 24V boats.
1,100lbsSuitable for use in 2006+ Moomba LSV and XLV boats and 2002-2008 22V and 24V boats.

Installation takes less than ten minutes from start to finish, and results in a factory quality installation with the additional weight you need to produce the best wake possible. The installation is accomplished by completing the following steps:

  1. Remove the factory ballast bag by releasing the red locking ring on the fill and drain connectors. Make note of which hose connects to the top of the bag and which hose connects to the bottom of the bag before removal.

  2. Insert the supplied fill hose extension into the end of the factory fill hose slide the red locking collar down to create water-tight connection.

  3. Place the new bag in the boat and reconnect the fill and drain hoses to the connectors, ensure the red locking ring is in the down position.

Absolutely no modifications are required, and the entire installation is completely reversible for resale value, or if you decide to reinstall your factory wakeboard ballast bags.

This upgrade is ideal for setting the boat up for surfing on one side, or both sides with two kits, and can also be used with additional weight in the bow of the boat to create a monster wakeboard wake.

ATTENTION: This factory ballast upgrade kit is sold individually. We sell systems individually so that customers can upgrade just one side of the boat for surfing if they would like. You will need to purchase two systems if you want additional ballast on both sides of the boat for wakeboarding or surfing regular and goofy. Contact us if you have any questions or need help determining the correct upgrade for your application.

    The bag works great!
    Ken Purchased this bag to replace my factory 400#. The 1100# bag shape fits better and makes a great surf wake. Next is the other side.

    Great service and product
    Mike This does what it's supposed to... worked perfectly with the 750lb bag upgrade in my Supra 20V. I'd have given it 5 stars all around except the hoses did not seal entirely from my factory hose to the plastic connector of the extension. Not a big issue, just purchased a couple of hose clamps and all is well, but if anything could be improved, that would be it. Nice product, came with everything I needed to (except hose clamps).

    Awesome and easy upgrade
    Gnarly It doesn't get any easier to upgrade ballast bags. I got the 1100 lb. kit and my 5 year old could of done the install. I can't wait to get on the lake and surf. Also this bag is shorter than the stock bag was so I have a little more storage under the seat since the new bag doesn't extend under it.

    Great product and so easy to do.
    walb0244 Great product. Purchased this bag to be able to create a bigger wave while surfing. The quality is great. I purchased the 1100 lb bags with this kit. Everything was right there in the kit and I had the bags installed in a matter of minutes. It took me longer to find something to cut the tape then it did to install the bag. Hahaha.
