Wakeboard ballast for MasterCraft BoatsTired of the above floor factory hard tanks in your MasterCraft wakeboard boat taking up too much storage space and not offering enough ballast? Replace them with our exclusive TankBuster ballast system upgrade for a massive wakesurfing or wakeboarding wake.

Instantly triple the ballast capacity in each rear corner, while at the same time restoring full use of the lockers for storage when you don't need the biggest wake possible.

Add an additional 400lb. 750lb. or 1100lb. ballast bag to your wakeboard boat's factory ballast system with our exclusive TankBuster Wakesurf Ballast System. Interested in adding more ballast to your boat for surfing, but don't want to mess with throwing pumps over the side of the boat? The WakeMAKERS MasterCraft TankBuster Wakesurf Ballast System is designed to integrate with your factory ballast system, be controlled using the switches on your dash, and not required any additional effort to fill and drain.


This TankBuster system is designed to work with any first generation X Series MasterCraft v-drive wakeboard boat with aerator pumps that has hard ballast tanks that installed above the floor in the rear lockers. That includes, but is not limited to, the following models:

- 1999-2001 X-Star

- 2001 X-10

- 2001 X-30

How It Works

The MasterCraft TankBuster Ballast System Upgrade takes the place of the existing factory hard tank installed in each rear locker of first generation X Series MasterCraft wakeboard boats. Once installed, the new ballast bag is controlled completely from the driver's seat, and uses the factory pumps and plumbing. Everything functions exactly the same as it did from the factory, but you've added more capacity. Additionally, when the bags are empty, the entire rear locker is available, dramatically increasing the amount of storage space for gear and equipment. This kit includes everything needed for the installation, including a new ballast bag and the necessary Fly High quick connect fittings.

Once installed, the three ports on the new Fat Sac are connected to the fill, drain and vent hoses from the factory ballast system, making the MasterCraft TankBuster a direct replacement. For convenience, Fly High Quick Connect fittings are used allowing you to easily remove the bag for cleaning, storage or winterization. Triple the capacity, double the storage space, all controlled using the factory dash switches makes the TankBuster is the perfect ballast upgrade.


The installation process is incredibly simple, completely reversible, and only has to be done one time to use the TankBuster system. Removing the factory tank and installing the new TankBuster bag typically takes a couple of hours to do both sides of the boat, so plan on leaving yourself and afternoon for the project.

Step 1: Locate and identify fill and vent hoses at the top of the factory ballast tank. The fill hose will come from down in the bilge of the boat, while the vent hose will go directly from the ballast tank to a fitting in the side of the boat.

Step 2: Remove hose clamps securing the factory fill, vent and drain hoses to the hard tank located in the rear compartment.

Step 3: Remove factory "L" brackets used to secure ballast tanks to the floor of the boat.

Step 4: Remove the drain pump from the factory hard tank by un-threading it.

Step 5: Remove the factory hard tank from the boat and retain in a convenient storage location.

Step 6: Insert pre-assembled fill and vent hose extensions into the factory fill and vent hoses and secure with the provided hose clamps.

Step 7: Attach the pre-assembled drain pump adapter to the factory drain pump.

Step 8: Secure the Quick Release connectors on the ends of the fill hose extension, vent hose extension and drain pump adapter to their appropriate connections on the new ballast bag.

Step 9: Test system for correct, leak-free, operation.

For specific questions on fitment, and for possible compatibility with other models, please contact us.

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.
