What Are Aftermarket Surf Tabs?
If you own a wake boat built before 2018 — or any inboard without a factory surf system — you've probably dealt with the old-school way of building a surf wave: load one side of the boat with as much weight as possible, pile your passengers to that side, and hope the result is rideable. It works, sort of. But it's inefficient, uncomfortable for everyone on board, and makes the boat handle poorly.
Aftermarket surf tabs solve this. They're aluminum plates mounted to the transom of your boat with hydraulic actuators. Deploy one tab and it redirects the water flow to create a clean, surfable wave on that side. Deploy the other and the wave switches. Deploy both and you've got trim tabs that get a loaded boat on plane faster.
The result is a symmetrically weighted boat that's easier to drive, safer for passengers, and produces a better wave than the old list-and-pray method — all controlled from the driver's seat with a joystick or switch panel.
Why Evolution Tabs
WakeBallast carries Evolution Tabs because they're the best-performing aftermarket surf system we've tested at a price point that makes sense. Here's what sets them apart.
More than a surf system
Most aftermarket surf devices do one thing: shape a wave. Evolution Tabs are fully functional trim tabs that happen to also produce an elite surf wave. You'll use them every time you're on the water — getting on plane faster when loaded, trimming the boat for rough conditions, leveling the hull at cruising speed, and improving fuel efficiency. The tabs create lift instead of drag, which means your engine runs at lower RPMs even when fully ballasted.
Built in the USA by people who surf
Evolution Tabs are designed and manufactured in St. George, Utah by Rob Andrus and his team. Every tab is professionally cut, bent, welded, and powder-coated in their own shop — not sourced overseas. Rob built these because he wanted a wave good enough to surf behind with his young daughter driving. That standard shows in the product.
Customer support that actually helps
Every system ships with written instructions and install videos. But the real differentiator is direct access to the people who built it — by phone, text, or FaceTime. If you get stuck during install, you can literally video call Rob's team and they'll walk you through it. That level of support is rare in marine accessories.
The wave speaks for itself
Evolution Tabs are engineered to produce tall, clean waves with serious push and length. The tab geometry creates consistent results every session — not a wave that varies depending on who's driving or how the weight shifts. Push the button and surf.
Which System Is Right for Your Boat
WakeBallast carries three Evolution Tabs systems. Here's how to pick the right one.
EVO SURF TABS
Most PopularThe newest standard-size tab design from Evolution. 20% less surface area than the Classic with two dagger fins, new mounts, and an updated shape — producing taller, steeper waves with less ballast weight. Compatible with all previous Evolution mounting hardware. The kit includes everything you need: tabs, actuators, controller, wiring, and mounting hardware.

NewestThe most advanced tab Evolution has ever built. PRO TABS feature removable, adjustable EVO FINS that let you fine-tune aggressiveness on the fly. Streamline the fins for high-speed wakeboarding and cruising, or angle them for maximum surf and hydrofoil performance. The first and only aftermarket tab that adapts to your activity — not the other way around. Complete system with everything included.

Specialty FitSame wave-shaping technology as the standard tabs, built at just 14 inches wide for boats with restricted transom space. If your boat can't fit full-size tabs, this system gives you a serious surf upgrade without forcing compromises. Perfect for 2004–2012 MasterCraft X Star, Toyota Epic boats, and Centurion Warriors.

Boat Compatibility
Evolution Tabs fit virtually any inboard wake boat produced after 2003. The system has been installed on every major brand:
If your boat isn't listed or you're not sure which system fits, text a photo of your transom to 801-404-3744 (Evolution's direct line) and they'll tell you which kit to buy. You can also contact WakeBallast and we'll help figure it out.
Installation — What to Expect
This is a permanent install, but it's well within DIY range. Evolution estimates 2-3 hours for someone with basic tools and garage mechanic confidence. Here's the overview:
Mount the tabs. The aluminum tabs bolt to the transom using Evolution's custom billet mounts. Placement is the trickiest part — especially on boats with contoured transoms — but the instructions are clear and the team will FaceTime you through it if needed.
Install the actuators. Lenco hydraulic actuators connect to the tabs and provide the movement. They mount above the tabs on the transom using the included upper mounting brackets.
Wire the controller. The joystick controller mounts on your dash. Wiring runs from the controller to the actuators. It's plug-and-play — no splicing into your boat's electrical system. Push left to surf left, push right to surf right, push forward to deploy both as trim tabs.
Auto-retract. The system auto-retracts the tabs when you turn off the boat. No forgetting to pull them up before trailering.
Tabs + Ballast = The Best Wave
Here's something every Evolution Tabs owner figures out on their first session: the tabs shape the wave, but ballast weight determines how big it gets. More weight means the boat sits deeper in the water, which gives the tabs more water to redirect. The result is a taller, longer, more powerful wave.
This is where WakeBallast's core product — steel shot ballast bags — pairs perfectly with Evolution Tabs.
Why steel shot bags are the ideal ballast partner for surf tabs
Symmetric weighting. With surf tabs, you don't need to list the boat anymore. You want equal weight on both sides. Steel shot bags in 25 and 50 lb increments let you distribute weight precisely and symmetrically throughout the boat.
Fill the gaps your water ballast can't. Your factory hard tanks and rear bags provide the foundation. Steel shot bags fill the spaces they can't reach — under seats, in the bow, along locker walls — adding another 200-400 lbs of ballast in spaces a water bladder won't fit.
Dial in while driving. You can physically move a 50-pound steel bag while the boat is running to fine-tune the wave. Try repositioning a full water bladder mid-session.
No pumps, no fill time, no drain time. Steel shot is always ready. Toss the bags in before you launch, arrange them where you want, and surf. When you're done, leave them in or pull them out in 60 seconds.

Will surf tabs work on my boat?
If you have an inboard wake boat made after 2003, almost certainly yes. Evolution Tabs have been installed on every major brand — Malibu, MasterCraft, Nautique, Axis, Centurion, Supra, Tige, Moomba, and more. If you're unsure, text a photo of your transom to 801-404-3744 or contact us.
Can I install these myself?
Yes. Most owners complete the install in 2-3 hours with basic hand tools. Evolution provides written guides, video walkthroughs, and direct phone/FaceTime support. If you'd rather not DIY, they can refer you to a professional installer.
What's the difference between EVO Surf Tabs and PRO TABS?
EVO Surf Tabs have fixed dagger fins and deliver excellent surf performance out of the box. PRO TABS add removable, adjustable EVO FINS that let you tune the tabs for different activities — more aggressive for surfing and foiling, streamlined for wakeboarding and high-speed cruising. If you do multiple water sports, PRO TABS give you more range.
Do I need the Narrow Tabs?
Only if your boat has limited transom space. The primary candidates are the 2004-2012 MasterCraft X Star, Toyota Epic boats, and Centurion Warriors. If you're not sure, measure your transom or text Evolution a photo.
How much ballast do I need with surf tabs?
More weight = bigger wave. Most Evolution owners run their full factory ballast system plus 200-500 lbs of supplemental steel shot ballast bags. Start with your factory ballast and add steel shot incrementally until you find your ideal wave. A common setup is 4-8 bags (200-400 lbs) distributed symmetrically.
Do the tabs work as regular trim tabs too?
Yes. Deploy both tabs simultaneously and they function as traditional trim tabs — getting a loaded boat on plane faster, improving handling in rough water, and reducing fuel consumption. This is one of the biggest underrated benefits. You'll use them every time you drive, not just when surfing.
What colors are available?
Evolution Tabs come in powder-coated black as standard. Some systems are also available in red, white, and blue.
Is there a warranty?
Evolution Tabs are backed by a manufacturer warranty. Contact us or Evolution directly for current warranty terms.
