350 Magnum Mercruiser Engine

Features approximately 300 prop shaft horsepower at 4,600 to 5,000 RPMs. If you are replacing a 5.0, 5.7, 305, and 350 marine engines the 350 Magnum is a great choice. Does not allow for converting; the 350 Magnum engine will utilize all of the outside parts of your old 305 and 350 engine. However, all other parts are the same, including the oil pan, timing cover, carburetor, valve covers, distributor, exhaust manifolds, balancer, and flywheel. Testing here at our factory has concluded that no adjustments are necessary to your computer.
