Following an intensive ten-year development programme, British diesel engine innovator, Cox Powertrain, has revealed the final concept of its highly-anticipated diesel outboard engine, the CXO300, at Seawork International, the commercial and workboat exhibition and conference taking place in Southampton, UK, this week.
The long-awaited engine will begin production in Q2, 2019 with order books opening in November this year.
The final concept of the CXO300 is based on the proven technology of a 4-stroke, V8 architecture. Cox Powertrain says it is the world’s first 300hp diesel outboard engine ever to have come to the marine market and claims it will deliver many advantages over competing gasoline outboards.
Cox Powertrain claims that for commercial operators, it offers at least a 25% better range compared to a gasoline outboard and is designed to last up to three times longer. It has a 100% higher peak torque at the crankshaft than the leading gasoline 300hp outboards and is 60% higher compared to a leading 350hp. This enables the craft to move more weight more efficiently, reach peak torque and top power more quickly.
The manufacturer says that users of equivalent powered diesel inboards will benefit from the flexibility of installing such a commercially graded diesel outboard engine. The CXO300 will deliver a package volume around half that of a state-of-the-art diesel inboard with comparable fuel efficiency. Benefits of reduced maintenance and haul out costs, minimised disruption to operation for engine service and repairs will be a big advantage.
The CXO300 has been designed and developed in-house from the ground up for professional maritime use in collaboration with Ricardo, an engineering and environmental consultancy. In a relationship that has lasted for ten years, Cox’s team of engineers have worked closely alongside Ricardo to deliver an engine technology that it says, will be transformational for the marine industry.
Sea trials of the CXO300 will commence in October this year and order books will open in November. The engine will go into full production in Q2 2019.
