Marine Equipment Trade Show, Amsterdam, 15th to 17th November 2016, Superyacht Pavilion Stand 11.401

British diesel engine innovator, Cox Powertrain, will preview its revolutionary marine diesel outboard engine, the CXO300, at this year’s Marine Equipment Trade Show. As the first ever 300hp marine diesel outboard, the CXO300 is the world’s highest power density diesel outboard, providing gasoline outboard performance, with diesel economy and reliability.

Cox has brought together highly skilled engineers from Formula 1 racing and premium automotive engine design to develop this completely new concept engine. The CXO300 is a patented opposed-piston, diesel outboard that is fully compliant with all the current emission regulations. Delivering 300hp and weighing only 300kg, it is the largest diesel outboard engine to be developed for the luxury yacht market eliminating the need to carry gasoline and associated equipment on board. It offers significantly lower running costs than its gasoline equivalent, longer service intervals and an expected lifecycle three times longer than a gasoline outboard.

Cox Powertrain is led by former Cosworth CEO Tim Routsis who commented, “METS is a highly important event for us to showcase our technology to the superyacht market and talk about its pedigree. In taking a clean sheet of paper approach through a five year development programme, our aim was to deliver diesel engine designs that combine best engineering practice with patented technologies to unlock new levels of performance and packaging.The CXO300 is now entering the final stages development so we are excited at the prospect of introducing this game-changing technology to the market ahead of its launch. ”

Cox is a British company based in West Sussex, dedicated to answering the demands of professional marine operators, with a reliable and powerful diesel outboard that eliminates the need for carrying gasoline. The development of a viable diesel outboard for RIBs and tenders, offering the comparable power and weight of a gasoline engine, has been an important factor in the rapid expansion of Cox Powertrain.

A full size model of the CXO300 will be displayed on Cox’s stand in the Superyacht Pavilion section of the Marine Equipment Trade Show. For further information, visit
