Most Powerful Outboard Engine Ever: Seven Marine 627

Seven Marine accomplished the feat by taking a 6.2L V-8 with a supercharged aluminum powerhead, built by GM for the Cadillac CTS-V, adding a computer-controlled disc-clutch ZF Marine transmission and double-walled stainless-steel exhaust, and turning the engine horizontal. Latham Marine helped design an internal power steering system, and the engine swings custom Herring propellers. These monster outboards immediately became popular, especially on high-powered center console yachts.
