Diesel outboards for passenger transport and marine tourism
Cleaner, more efficient propulsion for ferries, water taxis and unforgettable experiences on the water
Supporting passenger transport and tourism with sustainable performance
From island-hopping ferries to luxury eco-tours, Cox Marine diesel outboards are redefining what operators can expect from marine propulsion. Whether transporting tourists, local communities, or private charter guests, our V8 diesel engines offer a safer, more economical and more enjoyable alternative to petrol outboards – reducing emissions and keeping services running smoothly in some of the world’s most stunning and demanding marine destinations.
Passenger and tourism vessels must perform reliably in high-frequency service, often operating in harsh climates, saltwater conditions and tight turnaround schedules. The Cox Marine V8 is built specifically for this challenge, delivering high torque at low RPM, exceptional fuel economy and extended service intervals – all while supporting a smooth, quiet and comfortable experience for every passenger.
Why operators choose Cox Marine diesel outboards
Safe by design
Our diesel engines use compression ignition, removing the spark risk found in petrol outboards. This spark-free design enhances safety in busy marinas, enclosed spaces and resort docks.
Fuel-efficient for longer journeys
With better fuel economy than petrol alternatives, Cox Marine engines help keep running costs low while extending range between refuelling. This is particularly valuable for long-shift ferry services, island-hopping tours and remote destination access.
Reliable performance, reduced downtime
Designed for high-duty commercial use, Cox Marine outboards have extended service intervals and proven durability. That means less time in the yard and more time on the water.
Quiet, smooth operation
Passenger comfort matters. The Cox Marine V8 runs with significantly less noise and vibration than typical diesel engines, making it well suited for scenic cruises, luxury transfers and public transport alike.
