Diesel outboards powering oil and gas operations

Safer, cleaner marine propulsion for offshore energy

Supporting energy operations where it matters most

From the Gulf of Mexico to offshore fields along the US coast, offshore oil and gas operations demand equipment that meets the highest standards for safety, reliability, and environmental performance. Cox Marine diesel outboards are engineered to thrive in these critical environments, providing a dependable and spark-free alternative to gasoline-powered engines.

Cox Marine diesel outboards are already in use supporting oil and gas activity across the US Gulf region – whether it’s assisting with spill response or operating on support vessels kept on standby.

In many oil-rich areas, gasoline engines are banned due to the risk of explosion. The Cox Marine V8 diesel outboards eliminates this hazard with compression ignition, making it the obvious choice for offshore platforms and high-risk zones.

Why Cox Marine diesel outboards are ideal for the oil and gas industry

Spark-free safety

Gasoline outboards pose an ignition risk that diesel engines eliminate. In regulated environments where spark-ignition engines are prohibited, our outboards offer a compliant and inherently safer solution.

Extended operating range

With greater fuel efficiency than gasoline alternatives, operators benefit from longer running times and fewer fuel stops – ideal for vessels engaged in emergency response, logistics, or continuous support roles in the US.

Low maintenance, high uptime

Extended service intervals and ease of maintenance mean reduced downtime and lower operational costs – a crucial factor for vessels supporting 24/7 offshore activity.

Trusted by the industry

Cox Marine works closely with US distributors, operators, and OEMs across the oil and gas supply chain to deliver engines that meet the needs of today’s energy sector. From real-time support to planned maintenance programs, our commercial diesel outboards are backed by a nationwide service network and a deep understanding of the industry.

Key features – built for oil and gas environments

Ready for rough seas

Our twin-turbo V8 diesel outboard delivers high torque at low RPM, giving operators the control and power needed to navigate tough conditions with precision.

Easy to install and maintain

A universal transom mounting pattern and commercial-grade design make installation and servicing straightforward – even on large standby or spill-response vessels.

Minimising emissions, maximising impact

The V8 is certified to the latest environmental standards (EPA Tier 3, RCD II, IMO II) and delivers up to a 30% reduction in fuel consumption compared to similar gasoline outboards.
