British diesel specialist Cox Powertrain shared final production and performance data and announced that production of its high-powered diesel outboard, the CXO300, is imminent at the Fort Lauderdale International Boat Show, October 30 to November 3, 2019.
Following the global launch of the CXO300 at last year’s show, the key message for this year was that the CXO300 is entering the pivotal stage of production, with the first deliveries scheduled for the end of 2019.
Final production specifications and data has been collected from comparison tests of a pre-production twin CXO300 installation and a comparable petrol installation on Intrepid’s Nomad 345 34-foot Centre Console. At cruise speeds between 40-46mph the CXO300 performed fuel burns of between 20-28gph. The twin petrol 300hp engines on the same boat produced a fuel burn of 24-35gph at the same cruise speeds.
During the demonstrations, the engines were consistently reported to have low vibration, low operational noise, impressive torque, good responsiveness and no smoke.
Delivering 300hp at the propeller, the twin turbo CXO300 is the world’s highest-powered diesel outboard engine. Designed specifically for marine application, the engine is based on the proven technology of a 4-stroke, V8 architecture. The final production engines in three leg lengths – 25”, 30”, 35” – will weigh just 380kg.
