2020 Supra SL 450

The 2020 Supra SL 450 is a 23.4-foot inboard surf and wake boat built on a fiberglass deep-V hull with 4,000 lbs of subfloor ballast and Supra’s AutoWake hull-management system. It seats 17, runs on a 450-hp Indmar Raptor 6.2L V8 inboard, and is controlled through a multi-screen Vision Control Center touchscreen. The SL is Supra’s flagship full-size tow boat in the 450 series, offering the largest ballast capacity and most premium feature content in that class. A 73-gallon fuel tank and 102-inch beam give you range and stability for a full day on the water.

This rig handles the afternoon chop that builds on Flathead and won’t bog down when the wind turns on Whitefish Lake. The ballast system lets you shape the wake for wakeboarding or wakesurfing without constant adjustment, and the touchscreen gives you one-hand control of trim, ballast, and engine functions. You’ll find it on the floor at Whitefish Marine, or call us at 406-862-8594.
