303 TEST RUN ONBOARD Magnum-Donzi Triple 1250BP Mercury Outboards
September 18, 2025 test run of the 303 at Lincoln Rock State Park. Turn up the volume! At the beginning, we didn't know the starboard engine had died so that's why it was not accelerating properly at first. This boat is a 1967 Magnum-Donzi hull powered by 3 Mercury 1250BP Engines. The boat was purchased directly from Mercury Racing and Carl Kiekhaefer in the early 1970's. #mercuryracing #vintageoffshore #donzi #classicboat #boating #mercuryoutboards #raceboats #boatracing #mercurymarine #2stroke #towerofpower
