2024 Supra SA 400 used

The SA 400 in the Supra Lineup

Supra has been building performance wake boats long enough to earn genuine respect from riders who know the difference between marketing and actual on-water results. The SA 400 sits at the top of the Supra family, and the 2024 model year brought with it the kind of refinement that comes from a brand that has spent decades listening to professional riders and everyday families alike. This is not a boat that tries to do everything adequately. It is built to do a specific set of things at a very high level, and for anyone serious about wakesurfing or wakeboarding, those things matter enormously.

The “400” in the name is not an accident. It refers directly to the 400 horsepower Indmar Raptor 6.2L engine that powers this boat, and that number sets the tone for everything else about the ownership experience. When you have that kind of power working with a hull designed specifically for wave and wake generation, the results speak for themselves on the water. This particular example is a used 2024 model currently available through Southtown Watersports in Charlotte, NC, and it comes loaded with a set of options that make it a genuinely complete package for a new owner.

Hull Design and Engineering

The Platform That Makes It Work

The SA 400 rides on a 22.5-foot hull with a 102-inch beam, and those numbers tell you something important about the design intent. The wide beam gives the boat a stable, planted feel on the water that translates directly into wave consistency. When your hull is moving through the water and displacing it in a predictable, engineered way, the wave you produce at the back of the boat becomes more reliable and more shapeable. Supra has put real engineering time into understanding how hull geometry, weight distribution, and ballast interact, and the SA 400 is the product of that work.

The 28-inch draft keeps the boat accessible on a wide range of lakes and waterways, which matters a lot if you are riding on the shallower sections of Lake Norman or Lake Wylie around Charlotte. You want a boat that can move freely between your favorite spots without constant anxiety about the bottom, and the SA 400’s draft gives you that freedom without sacrificing the deep-water performance characteristics that make it special when you are out in open water.

Ballast and Wave Shaping

One of the most important things to understand about the SA 400 is how its ballast system and surf technology work together. Supra engineered this hull to work with integrated ballast that fills and drains efficiently, allowing you to dial in the weight distribution for your preferred riding style. More weight toward the back and one side produces a deeper, steeper surf wave on that side. Adjusting the distribution gives you a longer, more mellow pocket. The 400 horsepower engine means you have the power to push all of that weight through the water without feeling sluggish or underpowered during acceleration.

For wakeboard riders, the wake shape at various speeds and rope lengths is clean and well-defined. The SA 400 produces a wake with a firm, consistent lip that gives riders a reliable launch point, and the transition from the flat to the wake face is smooth enough that beginners can build confidence while advanced riders find the pop they are looking for. This boat genuinely works for the full range of skill levels, and that versatility is one of the reasons it sits at the top of the Supra range.

Power and Performance

Indmar Raptor 6.2L 400

The engine in this boat deserves its own conversation. The Indmar Raptor 6.2L is a purpose-built marine engine that was developed specifically for the demands of wake sports. It produces 400 horsepower and the torque curve is designed to deliver strong, consistent pull across the RPM range rather than just at peak output. For wakeboarding, that means the rider feels a smooth, confident pull out of the water and a steady tension on the rope throughout the ride. For wakesurfing, it means the boat reaches and holds its optimal surf speed without hunting or surging.

Indmar has a long history of building reliable marine engines, and the Raptor platform specifically was designed with the heat management challenges of inboard wake boat operation in mind. These boats spend a lot of time at low speeds with high loads, which creates a very different thermal environment than a typical runabout or ski boat. The Raptor’s cooling system and component design address those demands directly, and the result is an engine that holds up well over time when properly maintained.

At 400 horsepower, this is also an engine that gives you headroom. You are not running at the top of its capability during normal surf and wake sessions. That margin translates into longevity and a more relaxed ownership experience over the years.

Speed, Response, and Control

The SA 400 uses a speed control system that keeps the boat locked onto your target speed with precision. For wakesurfing especially, speed consistency is critical because even small variations can change the shape and position of the wave. When the boat holds its speed accurately, the wave becomes predictable, and the rider can focus on their riding rather than adjusting for a wave that is moving around. The throttle response from the Raptor engine is crisp enough to give you confidence during acceleration while remaining smooth enough that you are not throwing your riders around during startup.

The steering feel on the SA 400 is direct and confidence-inspiring. The hull tracks well at surf speeds and responds predictably when you need to make corrections. For the driver, this means less fatigue over a long day on the water, and for the riders, it means a more consistent experience because the boat is not wandering off its line.

Options and Equipment

PTMEdge VR-140X Mirror Upgrade

This boat comes with the PTMEdge VR-140X mirror upgrade finished in dark gray with black trim. If you have spent time on wake boats with lesser mirrors, you know how much a quality mirror matters. The PTMEdge system gives the driver a wide, clear view of the rider behind the boat without the distortion or vibration issues that plague cheaper mirror setups. The dark gray and black finish integrates well with the boat’s overall aesthetic, and the build quality of the PTMEdge system is genuinely in a different category from what comes standard on many boats.

Being able to see your rider clearly at all times is a safety issue as much as it is a convenience issue. The VR-140X’s wide field of view means you catch what is happening behind the boat quickly, which is especially important when you have newer riders who may fall unexpectedly or need you to respond fast.

Tower Speakers and Eight-Channel Amplifier

The tower speaker setup on this boat is a two-pair configuration running through an eight-channel amplifier, all finished in black to match the tower. Tower speakers on a wake boat serve a fundamentally different purpose than speakers inside the cabin. When you are wakesurfing 10 to 15 feet behind the boat, the sound from interior speakers disappears into the wind and engine noise. Tower speakers project outward and upward, putting the music where the riders are, and a properly powered setup makes a real difference in the experience.

Two pairs of tower speakers with a dedicated eight-channel amplifier means you have enough output to fill the space around the boat with actual sound rather than just noise. The amplifier gives each speaker the power it needs to perform cleanly at volume, and the result is a system that you can actually hear and enjoy while riding.

PTM ClampForce Board Racks

The PTM ClampForce board racks mounted on the tower handle your wakeboards and surfboards securely while you are underway. Board racks on a wake boat are one of those items that seem minor until you have a board come loose at speed, and the ClampForce system’s clamping mechanism holds boards firmly without requiring you to wrestle with them every time you load or unload. The tower-mounted position keeps the boards out of the way inside the boat, which matters when you have a full crew on board and you want to keep the interior space usable.

Boat Cover

The over-tower-down boat cover in black is a practical and important part of this package. A proper boat cover protects the interior, the tower, and the electronics from UV exposure, rain, and debris between uses. The over-tower configuration means the cover fits over the tower in its lowered position, giving you complete protection without having to partially disassemble the setup every time you put the boat away. For a boat that is going to spend time sitting between sessions, a quality cover is one of the most effective ways to protect your investment.

Boatmate Tandem Axle Trailer

The Boatmate tandem axle trailer included with this boat is a purpose-built towing solution for a boat of this size and weight. Tandem axle trailers distribute the load across four wheels rather than two, which improves stability at highway speeds and reduces wear on the trailer components over time. Boatmate builds trailers specifically for wake boats, which means the fit and support points are engineered for the hull geometry rather than adapted from a generic design. For anyone who plans to trailer this boat regularly, having a quality tandem axle setup from day one is a significant advantage.

The Charlotte Market and Local Riding

Lake Norman and Surrounding Waters

Charlotte sits in one of the best regions in the Southeast for lake recreation, and the SA 400 is built for exactly the kind of riding that happens on these waters. Lake Norman, the largest man-made lake in North Carolina, offers plenty of open water for wake sports along with coves and protected areas where the water stays calmer on busy days. Lake Wylie, straddling the North Carolina and South Carolina border just south of Charlotte, is another popular destination with a strong community of wake boat owners.

The SA 400’s draft and hull design make it well-suited for navigating these lakes, and the power of the Raptor engine means you are never working against the conditions. Whether you are dealing with a light chop on a busy weekend afternoon or glassy morning water at first light, this boat handles the range of conditions you will encounter on Charlotte-area lakes.

Southtown Watersports

Southtown Watersports in Charlotte, NC is the dealer for this boat, and their connection to the Supra brand goes beyond just selling the product. The team at Southtown understands wake sports from a rider’s perspective, and that knowledge shapes how they approach helping customers find the right boat and understand how to get the most out of it. For a boat like the SA 400, which has a range of settings and features that can be dialed in for different riding styles, having a dealer with genuine expertise makes a meaningful difference in the ownership experience.

Located in Charlotte, Southtown is well-positioned to serve the broader region of wake sport enthusiasts who ride on Lake Norman, Lake Wylie, and the other lakes within driving distance of the city. If you are in the Charlotte area and want to see this boat in person, Southtown is the place to start.

Why the SA 400 Stands Apart

Supra’s Commitment to Surf Performance

Supra entered the surf boat segment with a clear philosophy: build the wave first, then build the boat around it. That approach shows in how the SA 400 performs on the water. The wave this hull produces is not an afterthought or a feature that was added to an existing design. It is the result of intentional engineering decisions made at every level of the boat’s development, from the hull shape to the ballast placement to the surf system controls.

For riders who have spent time behind other wake boats and found themselves frustrated by waves that are inconsistent, too small, or difficult to position, the SA 400 offers a different experience. The wave is substantial, shapeable, and consistent, and the controls give you enough adjustment range to find the configuration that works for your specific crew and riding style.

Competing at the Top of the Market

The SA 400 competes directly with the best surf boats from Mastercraft, Malibu, and Nautique. Each of those brands has its strengths, and the competition between them has pushed all of them to build better boats over the past decade. What Supra brings to this competition is a combination of hull performance, value relative to the features you get, and a surf system that holds up against the best in the segment. The 400 horsepower Raptor engine is also a differentiator, because not every competitor in this size class offers that level of power as standard equipment.

For buyers who are evaluating multiple brands, the SA 400 is worth a serious test ride. The on-water experience is the most honest evaluation tool, and the SA 400 tends to make a strong impression when you put it back-to-back with its competition.

Long-Term Value and Ownership

Wake boats at this level of performance are a significant investment, and the long-term value of that investment depends on how well the boat holds up over time. Supra’s build quality has a strong reputation in the industry, and the Indmar Raptor engine is a proven platform with good parts availability and a strong service network. For a used 2024 model, you are getting a boat that is still very much in the early part of its service life, with the engineering and technology of the current generation.

The options on this boat, including the trailer, the cover, and the tower equipment, add real value to the package. Buying a boat that already has a quality trailer, a proper cover, and a capable audio system means you are not spending the first season of ownership tracking down and purchasing those items separately.
