Ultra Magnum Inboard Jet

UPWARD MOBILITY, LITERALLY. NOT TO MENTION NAUTICALLY

Throttle one up. Now with a wider 7’ bottom, redesigned gunwale, and available with new 6.2 liter supercharged V8, the Ultra Magnum is the biggest, boldest, baddest inboat jet ever! Its Hydro-Flow jet hull accelerates at a stunning rate, reaching planing speed in mere seconds. Smart engineering has achieved thrust and horsepower with a smoothness and sheer grace only once imaginable. The Ultra Magnum can handle everything from intimidating whitewater rapids to extremely shallow riffles and wide-open lakes. Whether on water, highway, or driveway, its styling is unmistakable. The craftsmanship is detailed to the point of absolute perfection. As the flagship of the Duckworth line, the Ultra Magnum offers something that’s quite nautically noble for the upwardly mobile.
