The World's First Professional Diesel Outboard

Lancing - United Kingdom, April 2017

The CXO300 diesel outboard engine is quite simply revolutionary. For the first time, the F1 concept of opposed piston architecture has been applied to a marine diesel outboard engine. The result is the most powerful, professional commercial diesel engine ever developed, with levels of efficiency and reliability to match.

Delivering an astonishing 300hp at the propeller and 550Nm Torque. Increased torque compared to 4-stroke gasoline outboards. Lasting three times longer than the average gasoline outboard.

Patented Opposed Piston Diesel (OPD) enables the four-cylinder, eight-piston supercharged 2-stroke CXO300 to achieve 1HP/KG - double the amount of a standard diesel outboard engine.


The CXO300 is designed specifically for commercial, government and military use where performance, durability and fuel efficiency are paramount

The simplicity of the design requires fewer parts; meaning less weight, less maintenance and less risk of failure. The perfect balance of the engine significantly reduces vibrations. Eliminating lubrication breakdown also prevents cylinder degradation and power loss.

As you'd expect from an engine designed for professional use, the CXO300 diesel outboard engine will also endure the most unforgiving marine conditions. A tough build and the reduced number of parts mean longer service intervals of around 1,200 hours and zero downtime in between. Oil and filter changes can be carried out without dropping the leg or dry-docking your vessel, while off-the-shelf propellers and minimum tool requirements also serve to minimise the time and cost of maintenance.

Dependable leg technology

Based on traditional leg technology to maintain a rugged simplicity, the CXO300's leg has been upgraded to handle the torque and durability requirements of professionals.

Centrifugal supercharger

In addition to a central fuel injector for optimal combustion, a centrifugal supercharger delivers greater fuel efficiency and is robust against water and salt ingestion.

Anti-corrosion systems

The CXO300 diesel outboard engine is predominantly oil cooled, with minimised internal surface area in contact with salt water. The lightweight aluminium alloys are protected by anodising and electrocoating. Paints developed with marine coating experts protect the external surfaces for the life of the outboard.

The power, performance and weight of a gasoline engine. The efficiency and reliability of a diesel outboard motor. Now you can benefit from the best of both worlds and leave compromise trailing in your wake.
