The M 25 C, part of the MaK long-stroke engine generation, is based on the proven design characteristics of the M 20 C, M 32 C and M 43 C engine series. When developing this new engine generation, the objective was to achieve a high benefit level for the customer. In all design and development considerations, therefore, three criteria had the highest priority: reliability, economy and environmental compatibility. Other points of significance in the engine's design and development work were ease of maintenance, long maintenance intervals, long component life and ease of installation.

Intelligent simplicity

This MaK design principles is most clearly reflected in the reduction in the number of components. About 40 % of parts have been dispended. It has resulted in a marked gain in operational reliability and a reduction in operating costs.

Reliable energy supply

The complete diesel engine is notable for its ease of installation, reliable operation, ease of maintenance and good component accessibility.

Low fuel consumption

Ready for installation

In addition to many outstanding technical features, the long-stroke M 25 C engine is also easy to install and provides good maintenance access to all components.
