Man Builds a 180HP JET SKI with a Motorcycle Engine | Full Build by @homemade_madness

In this full start-to-finish build, @homemade_madness designs and constructs a fully functional 180HP jet ski powered by a motorcycle engine. From shaping the hull and fiberglassing the body to engineering the jet propulsion system and custom exhaust, every step is built by hand using raw materials. This project combines precise engineering, creative problem-solving, and serious performance to turn an ambitious idea into a working machine. From the first cut to the final test on water, this is a true homemade jet ski build you don’t want to miss.
