Mud, stumps, rocks, nothing stops a GO-DEVIL®. Its reputation for unparalleled dependability and service has put a GO-DEVIL® in every state and province of North America. Since 1977, duck hunters, sport and commercial fishermen have experienced access to areas that no other marine engine can deliver with total confidence . Confidence that comes from over 31 years of research and testing in hostile conditions such as heavy vegetation, mud trenches, cypress swamp and rock-laden rivers. It's been called "The Four-Wheel Drive" of marine engines.
