Designed to comply with the latest emissions regulations while anticipating future market needs, a new generation of marine diesel engines 175hp to 245hp is entering the propulsion market, offering high flexibility and long-term reliability for both commercial and leisure vessels.
After an initial concept preview earlier in the year, the new M245 engine family was officially unveiled at METSTRADE, confirming the manufacturer’s belief that high-performance marine diesel engines with adaptable installation layouts will remain a cornerstone of marine propulsion for years to come. The range has been developed to address the diverse requirements of boatbuilders and refit specialists across a wide spectrum of applications.
The lineup includes three six-cylinder propulsion units delivering power outputs of approximately 173 hp, 200 hp and 249 hp at 2,400 rpm. Built around a proven common-rail fuel injection architecture, the latest-generation 7-litre platform has been engineered to ensure durability, operational stability and reduced lifecycle costs, key factors for commercial and leisure marine engines alike.
To support a wide variety of installations, the engines can be specified with multiple configuration options. These include mechanical throttle conversion systems, simplex or duplex filtration, single or double-wall fuel lines, and a selection of compatible marine gearboxes. Each unit can be tailored to meet specific classification society rules and certification requirements, offering a high degree of flexibility for new builds and refits.
Cooling solutions are equally versatile, with choices ranging from heat exchanger systems to keel cooling, separate cooling circuits or combined solutions. This adaptability ensures compatibility with different hull types, operating profiles and onboard layouts, reinforcing the appeal of these flexible marine diesel engine solutions.
Recognising the increasing pressure of global emissions legislation, the engines in the 175hp–245hp range are fully compliant with current international standards. These include RCD II, EPA Tier 3, IMO II and EU Stage V (for the lower power variants), delivering a future-proof marine propulsion system that supports regulatory compliance and long-term investment.
From a maintenance perspective, the engines are designed to simplify servicing and reduce downtime. Features include extended service intervals of up to 500 hours, a self-priming fuel system, self-tensioning belts with replacement intervals of up to 1,500 hours, gear-driven water pumps and automatic hydraulic valve adjustment. All routine service points are easily accessible, and optional flexible engine mounts further simplify installation.
Customers can choose between standard sensor packages or advanced alarm and shutdown systems, depending on operational requirements. Starting from a base configuration for each power rating, engines can be factory-specified and supplied ready for installation, providing a cost-effective response to the increasingly competitive marine propulsion engines market.
