VM Motori MR704LX Engine (NEW): Powerful, Modern, and Reliable 2.8L Marine Solution for 2025
The VM Motori MR704LX Engine (NEW) is one of the most powerful and modern 2.8 L marine diesel engines, designed for professional use in both recreational and commercial vessels. This four-stroke, turbocharged, and intercooled engine is distinguished by exceptional reliability, impressive torque figures, and advanced technologies that allow for maximum performance with minimal fuel consumption. With an excellent power-to-weight ratio and compact dimensions, the MR704LX is one of the most popular VM Motori solutions in 2025.
The engine features an electronically controlled direct fuel injection system “Common Rail,” ensuring precise fuel delivery, cleaner combustion, and reduced vibration. This means quieter, smoother operation and lower operating costs. Common Rail technology also increases engine power at low RPMs, which is especially important for vessels needing instant thrust when climbing waves, maneuvering in ports, or sailing against higher resistance.
The 2.8-liter displacement of this series is one of the main advantages of the MR704LX, allowing it to achieve high torque even at low RPM ranges. The engine maintains consistent performance, making sailing easier, more stable, and safer even in challenging sea conditions. The MR704LX is ideal for vessels that require a powerful yet economical engine capable of operating continuously for many hours.
The engine is equipped with a modern turbocharger with intercooling. The intercooler reduces the intake air temperature, improves fuel combustion efficiency, and allows for maintaining higher power without adding extra thermal load to the system. This gives the MR704LX engine an advantage over older marine units, which often experience temperature fluctuations and wear out faster during intensive use.
The MR704LX features a dual cooling system—one circuit for fresh water and another for saltwater. This design protects the engine from corrosion, reduces thermal load, and enhances the longevity of the entire system. Removable hoses significantly ease maintenance by allowing easy access to key components even in small engine rooms.
In addition to the cooling system, the MR704LX stands out for its minimized number of external flexible hoses. This significantly reduces the risk of leaks, increases the structure’s resistance to vibration, and enhances overall engine safety. Fewer external components mean fewer potential failures and simpler maintenance, which is especially valued by commercial vessel owners.
Compact dimensions and optimal weight allow this engine to be installed in a wide variety of vessels. The MR704LX is perfect for 25–45 foot yachts, powerful RIB-type boats, high-speed recreational and sports boats, commercial coastal vessels, technical workboats, and larger sailing yachts requiring a strong auxiliary power unit. This model is extremely versatile and can be used in both new-build vessels and as an excellent replacement for older engines when modernizing a vessel’s power unit.
The engine complies with international emission standards IMO, BSO, and RCD I, making it suitable for use in European and global waters. Such compatibility allows for international routes without legal restrictions. The modern pollution-reducing design not only saves fuel but also reduces environmental impact.
The standard MR704LX package includes a flywheel with housing, a powerful 12V starter, a 110A alternator, air, fuel, and oil filters, a bronze sea water pump, a fresh water circulation pump, a stainless steel gas-water mixer, an expansion tank, elastic mounting elements, and an electronic instrument panel with alarms. Additionally, a hydraulic reverse gear and flying bridge control console can be ordered if the vessel has an upper post.
The new VM Motori MR704LX Engine (NEW) is a combination of modern engineering and reliability, designed for those who want to experience true power, efficient fuel use, and contemporary comfort in one power unit. It ensures smooth operation, easy maintenance, high thrust, and maximum durability, making it an ideal choice for both professional mariners and recreational equipment owners.
