About Cox Marine
Cox Marine is transforming the marine propulsion landscape with a bold and innovative approach to diesel outboard technology. As a British company founded with the mission to deliver a cleaner, safer, and more efficient solution for marine operators, Cox Marine has spent over a decade reimagining what an outboard engine can be.
Instead of modifying existing automotive designs, Cox built its engines from the ground up, specifically for the marine environment. The result is the Cox Marine V8 – a 4.4-litre twin-turbocharged diesel outboard engine available in 300HP and 350HP variants, featuring high-pressure common rail fuel injection and advanced cooling systems.
Designed, tested and manufactured at Cox Marine's state-of-the-art facility in Shoreham-by-Sea, England, UK, the Cox Marine V8 produces exceptional torque at low RPM while significantly reducing fuel consumption. It meets the toughest global emissions standards including EPA Tier 3, IMO II and RCD II. Operators can expect up to 30% better fuel efficiency compared to traditional gasoline outboards, translating into real-world operational savings and extended range.
Whether for commercial, military, or recreational use, the Cox Marine V8 is purpose-built to thrive in the most demanding marine conditions. Cox Marine works with a global network of distributors to provide factory-trained support, fast local response, and genuine parts, revolutionizing marine propulsion for a cleaner, more efficient future.
