Texas-based boater and EV fan Scott Masterson combined his two loves to create a Tesla-powered speedboat. He bought a 2016 Bayliner 175 Bowrider and immediately pulled out its 3-litre Mercruiser engine – swapping in an HPEVS three-phase, sealed marine electric motor.

What did he use for energy storage? Tesla modules, of course. They were pulled from a Smart ForTwo Electric Drive. Masterson said the boat pack contains 330 cells, arranged in eight modules, configured for 24 kilowatt-hours of capacity. “These work particularly well in 48-volt marine and cart applications,” he wrote on his EValbum page.
