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.

Outstanding performance

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.
