Our story so far

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.

Vision turned into reality

Having met David in 2008, Charles became Chairman in 2009, and with his investor group, becomes the financier of Cox Powertrain and spearheads the development of David’s lightweight diesel into the powerhead for an outboard engine.
