Cox diesel outboard showcased on Axopar 37

Cox Powertrain’s Germany-based distributor, Diesel Power, has successfully installed a twin CXO300 diesel outboard configuration on an Axopar 37.

The British diesel outboard manufacturer Cox Powertrain has been working closely over the last few months with its Germany-based distributor, Diesel Power, and Axopar’s German dealer, Boote Polch, to commission the twin installation of the 300hp CXO300 diesel outboard on board an Axopar 37.

Cox Powertrain says of the installation: ‘With one of the most fuel-efficient hulls for fast motorboats, the Axopar 37 is an excellent candidate for showcasing the twin CXO300 configuration.’

According to the outboard manufacturer, the CXO300 diesel outboard engine offers 25 per cent better fuel efficiency compared to similarly rated gasoline outboards, a service life three times longer and highly competitive performance figures, including 479lb-ft torque (650Nm) at 2,250-3,000rpm.

“Axopar is at the forefront of boatbuilding innovation and is leading the recreational adventure boat segment,” comments Jan-Erik Viitala, founding partner at Axopar. “Cox’s CXO300 is an exciting alternative and, for the first time, represents a genuinely viable diesel outboard solution for the market; perfectly aligned with the needs and preferences of our ’go anywhere‘ type of boaters.”

During the sea trials with Axopar 37, which took place in Lymington, UK, Cox reports that with a smooth to moderate sea state, the Axopar 37 consumed 142.08 litres per hour at 4,000rpm, reaching a top speed of 41 knots. When further trials were carried out on the Mosel River in Germany in calm conditions, the Axopar 37 reached top speeds of 46.3 knots at 3,900rpm.

Peter Nauwerck, managing director at Diesel Power AB, adds: “The combination of the high-performance Axopar 37 and the market-revolutionising CXO300 diesel outboard is attractive for many market segments including the boat tender sector, geographical markets with a limited availability of gasoline and also for those looking for a dramatically improved range.”

The CXO300 has successfully received certifications from the main emission-governing bodies including EPA Tier 3, RCD II and IMO II, as well as BSO-II.
