Why operators choose Cox diesel outboards

Spark-free safety

Compression ignition removes petrol-engine explosion risk – a vital advantage in fuel-sensitive port areas and offshore zones.

Extended range and endurance

Better fuel economy than petrol alternatives keeps crews offshore longer with fewer refuelling stops.

Low maintenance, high reliability

Built for continuous heavy-duty use, the V8 features extended service intervals and robust marine-grade design.

Responsive control

Peak torque at low RPM ensures smooth starts and precise handling, even when fully loaded or in rough seas.
