Dan loaded up his 2008 Moomba Outback V for wakesurfing using the Moomba Gravity III factory ballast system and two additional Launch Pad ballast bags. The result as you can see from the video above is a very surfable wave. To get the most out of your Moomba Outback V Gravity 3 Ballast System replace your 400lb. rear ballast bag with the Wakemakers Moomba BagBuster Ballast Upgrade (2002-2008) or the Moomba BagBuster Rear Ballast Upgrade (2009-2011) depending on the year of your boat. Both ballast kits include the fittings and any necessary hose extensions you will need to replace the factory rear ballast bag with a larger Fly High Fat Sac.
