Maximize the factory ballast system in your 2002-2017 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 2002-2017 Supra and Moomba wakeboard boats equipped with the Gravity III wakeboard ballast system from the factory. Determine the perfect weight for your boat with the option to add between 610 and 1400 pounds of ballast using our WakeMAKERS UniversalFIT Rear Ballast Bags. For 2002-2008 models 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. 2009 and newer models will not require this extension.

Moomba BagBuster Plug 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.

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 a 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.

    Best ballast upgrade kit on the market
    Steve iovinelli

    I bought the 1140# WakeMAKERS Moomba BagBuster Rear Factory upgrade with the engine divider panel saver kits for both rear lockers and the surf wave is now incredible. Plenty of push with a long riding area. Couple this purchase with a Mission Delta Wake surf device from WakeMakers and we have one of the biggest waves to surf on the lake. 2007 Moomba XLV, 2700# G3 ballast. Thanks WakeMakers.

    Perfect and so easy!
    Greg Bringhurst

    Came quick, literally take out your old bags and plug these right in. Came with the hose extensions needed for the bags being bigger. Went from rear stock 400's to 910's and couldn't be more happy. Perfect fit.

    Happy at this point
    Bobby Shaffer

    I ordered these bags and it was so easy to install that my wife installed the first bag (I just had shoulder surgery). The second bag had an issue with the plug not fitting correctly. I contacted wake makers late Friday and was told a new bag would be expedited on Monday. I will update soon but at this point I am very satisfied. Super easy install and great price!

    Quick and Easy

    I have a 2005 Moomba XLV and these 1,100 lbs bags made a HUGE difference in my wake for surfing. Very happy with this purchase. The guys were great to work with and gave me some good ideas. Will buy from Wake Makers again!

    The bag works great!

    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

    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

    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.

    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.
