Instantly improve the surf wake behind your 2002-2004 Malibu Wakesetter boat with the fastest and most affordable hard tank replacement factory ballast system upgrade.


New and Improved!

Our exclusive Malibu TankBuster upgrade solution has been completely re-engineered for better performance, more accurate control of water level in the bag, and even easier installation.

Get the Wake You've Always Wanted

Unlock your boat's performance by adding over triple the capacity to the factory ballast system.

The factory rear hard tank in your boat currently holds 250 pounds of water. Our TankBuster upgrade will add over 600 pounds of wake building capacity to that number by removing the factory tank and replacing it with a larger capacity bag. That gives you almost 900 pounds* of total weight in each rear locker! Just imagine the improvement in the surf wake you'll see with that much additional weight.

A Perfect Fit For Your Malibu

Designed specifically for the boat they will be installed in, our TankBuster upgrade systems are guaranteed to fit and perform perfectly.

Simple installation and a perfect fit is the goal with our factory upgrade solutions. Trust the experts that your system will work exactly as you expect, because it's made just for your boat. We always recommend getting the maximum capacity possible in each rear locker, as that will give you the ability to build the best wake, even if you don't use that full capacity every day.

Easy DIY Friendly Installation

Seriously, install it yourself in 20 minutes, no trip to the dealer necessary.

Our TankBuster upgrades are designed to be installed quickly and easily by you! In fact, the entire installation can be performed with just a screwdriver and many customers tell us they finish the installation in less than 15 minutes. Oh, and did we mention it's completely reversible with no modifications if you decide to sell your boat?

Of course if you would prefer to let the professionals handle it, any dealership or marine service center will be happy to take care of the installation for you.

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.

    Easy and awesome
    jeff 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.
    Clary 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
    Matt 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
    PAUL 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
    buck 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
    Daniel 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!!!!
    Higbee646 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!
    KrisT 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
    Jeremy 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
    Mike 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!
