The world's most powerful diesel outboard engines boosting fuel efficiency

Elevate your maritime adventures with Cox Powertrain’s distinguished offerings: the CXO300 and the new V8 350. These V8 diesel outboard engines are masterpieces of power and innovation, tailored for both spirited recreational escapades and demanding commercial applications.

The CXO300, with its robust 300 hp output, revolutionizes marine propulsion through unmatched torque, superior fuel efficiency, and remarkably quiet operation. Complementing this, the V8 350 stands as a beacon of strength and eco-conscious engineering, claiming the title of the most powerful diesel outboard in the market. Together, they set a new standard, embodying Cox Powertrain’s dedication to performance, durability, and environmental stewardship.

Retrofit compatibility

Although the first of its kind, the CXO300 and the V8 350 has been built for purpose and developed according to industry standards. This means it is compatible with current controls (NMEA 2000), propellers, transom bolt pattern and steering systems. It is as easy to install and handle as any petrol outboard.
