The engines achieved a cruise speed of 43 knots at 3,600 rpm, with Naval Sea Systems Command (NAVSEA) testers reportedly expressing great enthusiasm and excitement about their performance.
The US Navy has been exploring the use of technologically advanced engines with the aim of improving combat readiness, crew safety and equipment supportability. NAVSEA is responsible for delivering the best possible equipment and systems to the US Navy.
Cox Powertrain’s Global Sales Director, Joel Reid, commented: “This first round of the in-field validation programme has gone extremely well and exceeded all expectations. NAVSEA’s testers seemed impressed by the smoothness of the engines and the absence of noise and smoke, which is historically associated with diesel engines. We were delighted that the two CXO300s went beyond their target to achieve a cruise speed of 43 knots”
Winner of the Innovation Showcase award for Marine Power at this year’s Seawork, the CXO300 has generated worldwide interest from civil and government agencies operating fleets of fast response vessels. This game-changing diesel outboard offers the ability to meet the demands of NATO’s single-fuel policy, as a safer alternative to petrol, while also providing exceptional performance and greater range than equivalent 300hp petrol outboards.
Cox’s engineering team, led by Stephen Moore (previously Director, Base Engine Engineering at Ricardo), has spent over a decade developing and perfecting the highest power density outboard ever created for a marine application. With a four-stroke V8 architecture and a package of similar size and weight to a petrol outboard equivalent, the CXO300 delivers the performance and efficiency of an inboard with the convenience and flexibility of an outboard. The CXO300 offers at least a 25% better range and 100% higher torque than leading 300hp petrol outboards, enabling the craft to move higher displacement vessels more efficiently and get vessels onto the plane quicker.
As previously reported in Seawork news, production of the CXO300 is set to commence at Cox’s state-of-the-art manufacturing facility later this year.
