Cox 300 V8 / 350 V8 · Single-fuel strategy
NATO compliant.One fuel.Simpler logistics.
No need for a separate petrol supply.
Fewer fuel types to manage. Safer fuel handling.
SAFER HANDLING / SIMPLER SUPPLY
Diesel’s higher flash point reduces the risk of fuel vapour ignition compared with petrol, making it safer to store and handle. Cox specifies compatibility with NATO’s Single Fuel Policy for its 300 V8 and 350 V8 diesel outboards.
The policy. The fuel. The engine.
Cox 300 and 350 V8 outboards are approved for a wide range of commercial diesel and NATO fuels, including EN 590 diesel, HVO meeting EN 15940, and NATO F-54, F-75 and F-76.
Contact Pontus Liljequist for approved fuel specifications and guidance for your application.

Diesel outboard range / Neander & Cox
Different platforms.
The right propulsion.
Select for the task. Compact support boats, fast-response craft and uncrewed platforms demand different power, payload and endurance. Neander and Cox give you distinct diesel options — with Dpower defining the configuration and integration around your operational brief.

Outboards / Built around the task
Fast response.
Flexible platforms.
Patrol. Interception. Troop transport. Different tasks demand different hulls — and propulsion selected for the load, speed and time on station.
01 / Patrol & maritime securityCover more water.
Stay on task.
Cox diesel outboards burn less fuel than comparable petrol outboards, giving patrol craft longer range from the fuel on board. Fewer refuelling stops. More time on task.
02 / Fast response & interceptionSpeed with
the working load.
Cox V8 torque delivers strong acceleration with crew and equipment aboard. Power to get loaded craft moving and reach the task quickly.
03 / Troop transport & landing supportSpace for people.
Capacity for equipment.
With the engines on the transom, more space inside the hull is available for troops, equipment and supplies.

Already in military applications
Proven applications.
Future ambition.
Cox diesel outboards are already used in military applications. In 2025, Cox announced a 92-engine order for a European military fleet, through De Wolf Maritime Safety.
MAN engines also power the Armed Forces of Malta’s P21–P24 inshore patrol vessels, each equipped with two D2842 LE410 engines.
