Adding ballast to your wakeboard boat's factory ballast system with our exclusive Malibu 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 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.

How It Works
The TankBuster Ballast System Upgrade takes the place of the existing factory hard tank installed in each rear locker of certain Malibu 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 an addition few hundred pounds of 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 Flow Rite quick connect fittings.

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.

Once installed, the three ports on the new ballast bag are connected to the fill, drain

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.

    Perfect in '04 Malibu 23 LSV
    John Morris

    I ordered the TankBuster kit with the 800lb Ronix sacks and couldn't be happier. Everything was included and the install was super easy. All fittings included, hoses cut to proper length. The hardest part was getting the old hard tanks out. Awesome service + fast shipping + great product = winning.

    Easy and awesome

    I have a 04 lsv and this swap out gave me an additional 750lbs vs the 200 that comes stock. Very easy to pull out the old one and very easy to install.

    Great idea - wake sac installation packages.

    Wake sac update packages for your specific boat, nothing to engineer, Awesome, buy and install it. Saving a lot of time = money...

    Malibu tank buster

    Took 2-3 hours. Very easy. The wake is big and I don't have to add as many bags now. The 1500 lbs in the back make a huge wake.

    Malibu Tankbuster Rear Factory Ballast Upgrade - FANTASTIC

    Purchaced two kits to convert my 04 Wakesetter VLV, comprehensive instructions on how to fit. Hardest part was disconecting the hoses from the old hard tanks, but even with this had both tanks changed in one hour. The kit came with everything needed exactly when they said it would arrive. Now have a great wake plus lots of extra storage when empty and it will make winterizing far easier at the end of the season. Many thanks wakemakers.

    Ecellent Product

    This is by far the easiest install I have ever done. It literally took less than 45 min to remove the old tanks and install the tankbuster system. The bags are top qaulity and the kit comes with everything you need to install it easily. The wake behind the boat is crazy now and we couldn't be happier!

    Must have upgrade

    After taking out the hard tanks the install was easy and idiot proof.
    I've got so much more room and love the added ballast.
    The quick connects make taking out the sac for cleaning or drying out so much easier.

    OH YEAH!!!!

    Installation on my 2003 LSV23 took about 30 mins. and was super easy. The setup looks great and like it's supposed to be there. Not just a cheesy add on. The hoses and connectors wear sized correctly and snapped together easily. The wake/wave is insanely huge and makes surfing a snap. I did have to keep a close eye on the left side compartment divider. It is VERY flexable and if the bag is not centered in the compartment the huge amount of weight in the full bag will collapse it out of the mounting tracks. I think some basic reinforcement will be necessary. I'm VERY happy with the product and the customer support from Wakemakers.

    Makes a HUGE difference!

    So convenient to simply push a button and have the sac fill with the rest of the ballast system. Very easy to install. I plumbed it into my factory ballast system easy even a girl can do it! :-)

    Great Addition

    Got everything installed and tested it out today. Pretty awesome wakeboard wake with bags half full and simple surf setup. Just two of us in our boat we filled the right 750lb bag, center ballast with wedge down and it was a super fun surf wake. Thanks again.

    Get rid of the factory hard tanks - TankBuster is the only way to go

    I purchased the 750 TankBuster system for my 07 vRide a few weeks ago and can honestly recommend it to anyone who wants a larger wake. The extra 500 lbs made a huge difference with the added bonus of no more “throwing the pump” which inevitably no matter how careful we where would end spilling some water in the boat. This is so simple – just like the 250 lb factory hard tanks – I flip my factory switch to fill – flip my factory switch to drain.

    Additionally by being able to remove the hard tank, the system gives you a bunch of additional space to store your gear. Installation was easy and when I had a question the crew at WakeMakers where very knowledgeable and willing to help me out. If you are like me and wanted to have a major increase in your wake, but hate the “throw the pump” process – this is the system for you. Oh and in case I forget to mention HUGE WAKE!
