Cox Marine

Cox Marine is a British company that designs and manufactures high-performance diesel outboard engines for boats. Their focus is providing an alternative to traditional gasoline outboard motors by offering diesel-powered propulsion systems that are built for greater efficiency, durability, and safety in demanding marine environments. The company primarily serves commercial operators, government agencies, military users, and some recreational boaters who need reliable long-range performance rather than lightweight or casual boating equipment. Their core products are large V8 diesel outboard engines, and they also provide supporting services such as dealer support, maintenance, and technical assistance to help operators use and maintain their engines effectively.
