The 2023 MasterCraft NXT21 is a 21-foot fiberglass ski and wake boat powered by a single 380-horsepower ILMOR 6.0L MPI engine. With 38 hours on the engine, this one-owner boat was serviced in April 2026 and has been used exclusively in freshwater.
The boat comes equipped with the Surfstar System for wake shaping, featuring side-to-side switching, electric over hydraulic actuator controls, positioning sensors, an attitude adjustment plate, and tracking fins. The ballast setup includes stock tanks and plumbed bags for customizable weight distribution. A Z6 tower with dual silver S70 cans and pop-up ski pylon supports water sports operations, complemented by a stereo transom remote and acrylic walk-through door.
The entertainment system pairs a Klipsch Commander radio with Bluetooth connectivity to four 7-inch speakers, a 10-inch subwoofer, DSP module, zone control, and an 8-channel amplifier. Onboard conveniences include a depth finder with water temperature display, mooring cover, Bimini top, SeaDek tan flooring, cleats, anchor cleat, and dual battery switch. A 2023 MasterCraft trailer is included with the boat.
