Our story so far

Back in 2009, 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.

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.

Thirteen years on, 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.

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.


How it all began

Charles Good begins his search for a lightweight diesel engine capable of satisfying the large global demand for a diesel outboard engine which he had identified.


Vision turned into reality

Charles meets David Cox and becomes Executive Chairman, 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.


First Fire

The first fire of Cox’s concept engine and commencement of designs for the Alpha engine.


Alpha Engine

Significant Growth

Tim Routsis joins as CEO, driving the business on and taking on new premises at Shoreham (Brighton City) Airport.


Distribution Network

Work to secure a global distributor network begins with an expected 50 distributors worldwide to support the launch of the CXO300.


Production line is built

World-class production facility at Brighton City Airport is built in anticipation for launch of the CXO300. Production staff commence employment.


Production Begins

Following EPA Tier 3, RCD II and IMO Tier II certification, Cox Powertrain commences production of the CXO300 with the first units shipped to the market in July 2020.
