Back in the 1970s, the Spirit Marine Wetbike made Suzuki-powered waterbike dreams come true. Right now, if you move fast, you can get your hands on a 1978 example that’s located in Utah, before the 2023 summer months even hit North America.
It’s powered by a 723cc two-stroke twin cylinder engine, which made a claimed 50 horsepower when new. (By the way, if you’re wondering whether horses can swim, the answer is yes—and their large lungs apparently make them quite good at it if they stay on the surface.) This engine uses a pair of Mikuni carburetors, as well as a reed valve intake system to breathe. This specific example also had its battery replaced in anticipation of the sale.
