Ultra Magnum Inboard Jet

Go Places You Never Knew Existed.

You’ll never say “if only” in Duckworth’s Ultra Magnum Inboard Jet. The ultimate off-road vehicle, the Ultra Magnum has conquered some of the most challenging, demanding and just plain wild water on the planet…and won! Powered by a powerful V8, this is the biggest, baddest, boldest inboard jet ever! Its Hydro-Flow jet hull accelerates at a stunning rate, reaching planing speed in an instant. Bring it on --- from intimidating whitewater to shallow riffles and everything in-between. Duckworth’s Ultra Magnum makes the unknown your playground.
