Cox Powertrain to Perform in-water Demos of High-Performance Diesel Outboard at DSEI

This year’s show will provide a prominent platform to showcase Cox’s CXO300 to the world’s defence and security audience for the very first time

DSEI 2019, ExCel London, 10th to 13th September, Stand S10-248

Lancing, UK, 27th August 2019 – Following the recent announcement of the successful completion of on-water validation programmes by the US Navy, Cox Powertrain will be participating in live action demonstrations of its CXO300 diesel outboard engine to visitors at this year’s DSEI, ExCel London.

The demonstrations will take place twice a day throughout the four-day event and will showcase the engine’s high speed and performance, which will be of particular interest to operators of fast craft within the defence, security and government agency fields.

The demonstrations will offer quayside onlookers the chance to witness the engine’s speed capabilities without any restrictions. During the recent U.S Navy tests, the CXO300 achieved a cruise speed of 43 knots at 3,600 rpm. The demonstrations will also highlight the handling of the engine which boasts 100% higher peak torque at the crankshaft than the leading gasoline 300hp outboards. This enables the craft to move more weight more efficiently, and reach peak torque and top power more quickly.

As a heavy-duty diesel-powered outboard engine, the CXO300 brings reduced maintenance and haul-out costs, reducing disruption to the vessel’s operation, which is another critical requirement for civil and government organisations operating fleets of fast response vessels.

The CXO300 has already 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 gasoline, while also providing exceptional performance and greater range than equivalent 300hp gasoline outboards.
