MAN Engines – a division of MAN Truck & Bus – develops, produces and sells diesel engines for workboats with 6, 8 or 12 cylinders rated at 190 kW to 1,324 kW (258 hp to 1,800 hp).

For heavy duty operation – with unlimited operating hours and working up to 100% full load – such as for tugboats and other working ships, MAN Engines provides a range of outputs from 190 kW to 735 kW (258 HP up to 1,000 HP).


In medium-duty operation (up to 4,000 hours per year at 50% full load), such as for ferries, passenger ships, and fishing boats, the range of outputs extend from 294 kW to 1,029 kW (400 HP to 1,400 HP).
In light-duty operation (up to 1,000 hours per year at 20% full load), the MAN engine range offers efficient 6-, 8- and 12-cylinder engines from 537 kW to 1,324 kW (730 HP to 1,800 HP) for escort, ambulance, and police boats.


A characteristic feature of MAN marine engines is their powerful acceleration coupled with an extremely low fuel consumption. Their advantages are to be found above all in their outstanding power efficiency and compactness. The engines are delivered ready for installation, and are designed for optimum performance in the various conditions of deployment and operation. After installation MAN offers to examine and pass off the engine and to carry out extensive commissioning. All engines comply with the internationally applicable exhaust-gas regulations.
