M 25 E Marine Propulsion Engine
Commercial Propulsion Engines
-
Specification Summary
- Power Range2100-3150 kW
- Speed Range720-750 rpm
- EmissionsIMO II
- AspirationTurbocharged
- Bore255 mm
The new M 25 E has been designed to completely meet the ultimate customer requirements, providing the lowest cost of operation while maintaining the highest uptime in the industry. Since one engine standard typically does not fit all applications, different M 25 E configurations will be available to support various application-specific requirements. Based on the proven M 25 C, all versions have been extensively optimized for best fuel consumption and load acceptance, leading reliability and durability, and efficient Selective Catalytic Reduction (SCR) operation. The service and maintenance-friendly design, remote condition monitoring and diagnostic capabilities, as well as our unmatched global product support, respond to the industry’s desire to lower operational costs and down times beyond today’s standards.
