In case anyone was accusing supercharged, the 556-horsepower LSA V8 that powers the Cadillac CTS-V of lacking versatility, refer to this video and stand corrected. Custom boatbuilder Seven Marine has taken the enormously powerful engines and adapted them to a marine outboard application.
According to Seven Marine, its 557 is the most powerful outboard ever made. The grunt is channeled to the water through an electronically-controlled ZF transmission. The Seven Marine 557 is also the first outboard ever to be joystick-controlled.
According to Seven, it can be hung as a single-engine setup on a 25 to 27-foot boat, or in a double, triple or quad setup on boats ranging up to 55 feet. Seven Marine claims the engine should be good for a 10-20 percent efficiency and performance increase over standard onboard engines because it requires fewer gear sets to operate, which means less drag. You can check the CTS-V-powered marine setup in the video after the jump.
