Diesel Power


The 300 hp diesel outboard that redefines standards

CXO300 from innovative Cox Powertrain is a high powered V8 diesel outboard engine designed specifically for commercial and recreational use. The 300 hp engine delivers high torque at low revs, giving the boat outstanding performance and manoeuvrability. Moreover, this commercial rated diesel outboard promises 30% better fuel efficiency, lower maintenance cost and three times longer service intervals compared to petrol-powered outboards. It runs quietly, with minimal noise or vibration.


The CXO300 is primarily suitable for planing boats in transport, governmental agencies, maritime rescue, and professional duties as well as for larger leisure boats / yachts.

Retrofit compatibility

Although the first of its kind, the CXO300 has been built for purpose and developed according to industry standards. This means it is compatible with current controls (NMEA 2000), propellers, transom bolt pattern and steering systems. It is as easy to install and handle as any petrol outboard.

Owning a COX diesel outboard gives you access to a global 24/7 customer support network should you need service or assistance. There is also an online Customer Portal where you can access knowledge articles, request assistance of book service.
