Supra Swell Surf w/ AutoWake


The Supra Swell System delivers tall waves with long pockets and optimal push that are consistent on both sides. Perfect for riders who like to transfer from side to side. Together with our game-changing AutoWake, you’re always in a position to throw the ideal wake or wave

Precision engineered wakes and waves.

AutoWake® takes the guesswork out of wakes and waves. This patented, industry-exclusive hull management system automatically manipulates the hull position to produce a precise wake or wave — every time. And it does it all without interrupting passengers or distracting the driver. Not only is AutoWake technologically impressive, it’s also an impressive feat of engineering. It’s as simple to operate as it is effective

All-new Heated Captain’s Chair


Boldly designed with exposed frame and inset accents, these advanced seats offer many standard features not seen in competitive products like software integration, power motion and heated base and back.

3,500 lbs Sub-Floor Ballast


The Mega Velocity Ballast System in the SL holds a huge 3,500 lbs sub-floor ballast. The system uses six pumps to reduce fill times and uses advanced ballast sensors to deliver pro-level wakes and waves

JL Audio


In addition to dual 10” M-6 subwoofers, 7.7” bow and 8.8” cockpit speakers, add up to four 8.8” M-6 JL tower speakers to push your premium JL Audio sound to the next level

Torque: A Wakesport Philosophy

Off-the-line boat planing and lightning fast rider pulls are now a reality thanks to Raptor by Indmar’s low-end RPM power technology—aka—Torque Centric Performance (TCP). TCP provides best-in-class torque and horsepower where you need it most: between 2,500 and 3,500 RPMs. Even with full ballast and a maxed out crew onboard, Raptor delivers immediate throttle and plane for unparalleled performance in wake sport applications

Standard 1.76:1 Transmission Gear Ratio

Your Supra engine is fueled by Raptor power that’s matched to a new standard 1.76:1 transmission gear ratio to maximize torque. This ideal gearing squeezes more performance from the powerband where it’s used most often, particularly when surfing

Smarter Engines Sip Fuel.

Raptor 6.2L engines run inherently more efficiently, giving you more low-end power with less fuel consumption. The Raptor’s wide-band 02 sensors deliver better fuel economy through a broader RPM range with dual spark plugs creating more efficient cylinder combustion. It means more time on the water and less time at the pump
