Maximize the ballast system in your 1999-2001 MasterCraft wakeboard boat.


Tired 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.

Malibu TankBuster Applications

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

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.

    Simple Installation, with Caveats

    First off, WakeMakers provided their usual quick service and fast shipping. The main advantage of buying here, though is the service you get both before and after the sale. I talked with the WakeMakers folks several times before my purchase, just to make sure that I was purchasing the right equipment for my application. I placed the order on Monday and had the TankBuster kit on Wednesday.

    Friday evening I surveyed the rear lockers in my 2001 Mastercraft X30. I knew that I would have to remove the hard tanks, but I realized I also needed to relocate the dual batteries that were sitting right in the middle of the locker. Several extra pieces of carpet-covered plastic had been installed to mount the Perko switch, breakers, etc. These had to be removed, but once they were out, there was plenty of room for the batteries well out of the way of the sacs.

    Saturday morning I completed the relocation of the batteries and I started removing the hard tanks. The brackets were sort of hard to reach, but once they were out the first tank came out easily. The second one got turned to a weird angle, so it took about thirty minutes to get it realigned where I could remove it from the boat. Once they were out, the actual TankBuster installation probably only required about an hour, tops.

    The only problem (if you can call it that) that I encountered was getting the barbed fittings into the existing hoses. Detergent, heat gun, brute force, and lots of cussing later, it was together. I haven't had a chance to get the boat on the water, but I am excited about the day I get to use my new toys.

    One thing to pay attention to: there are brackets with heavy bolts by the engine compartment that could present a possible hazard to the bags. I'm sure that most boats have the same situation. Just make sure you have some leftover carpet or other type of material to prevent damage to the vinyl.

    The only issue
