Engineered for professional performance

The Cox Marine V8 diesel outboard has been designed to offer a direct replacement for petrol engines with none of the safety concerns or inefficiencies.

The commercial advantage of diesel
Safety first
In oil and gas zones, spark ignition engines are banned for good reason. Our compression-ignition diesel outboards eliminate this risk, making them the preferred choice for hazardous environments and border patrol operations alike.
Longer operating range
With at least 30% greater fuel efficiency than petrol alternatives, Cox outboards let you travel further and operate longer – ideal for patrol boats, spill response vessels, and long-haul fishing trips.
Low maintenance, high uptime
With extended service intervals and robust engineering, The V8 is designed to reduce downtime and lower total operating costs – crucial for busy fleets across the Gulf, Indonesia, and Australia.
