Product category: Outboards Diesel


Designed from a blank sheet of paper for both commercial and recreational use, the CXO300 offers up to 30% better fuel efficiency compared to a 300hp gasoline outboard, a service life that is three times your average outboard, and highly competitive performance, including 479 lb.ft torque (650Nm) at 2250-3000 RPM. The CXO300 offers a new generation of diesel power, delivering the same performance and packaging of a gasoline outboard but with the fuel efficiency, safety, and reliability of a diesel inboard.

About us

Company portrait

Back in 2010, Cox Powertrain started its mission to deliver a revolutionary new concept in ultra-lightweight diesel engines. This ignited the beginning of the CXO300. A high powered, diesel outboard engine.

Since then, Cox has successfully raised over £120 million of private investment, in order to bring the outboard from a dream to a reality. Having begun production in May 2020, the CXO300 is becoming hugely popular in the market and the demand is only expected to rise.

With experienced engineers from premium automotive combustion backgrounds, Cox took the best from the automotive world and combined it with the very best technologies from the marine industry, to design and build the next chapter in diesel engines.

The high powered 300hp diesel outboard engine is an innovative product offering a new marine propulsion option and is redefining standards within the maritime industry. Delivering the same performance and packaging of a gasoline outboard but with the fuel efficiency and reliability of a diesel inboard, this purposefully built outboard has begun to revolutionise the market.
