VM Motori MR704LH Engine (NEW): Powerful and Advanced 2.8L Marine Engine.
The VM Motori MR704LH Engine (NEW) is a modern 2.8-liter, four-stroke, turbocharged, and intercooled marine diesel engine designed to ensure maximum reliability, powerful thrust, and low fuel consumption even under the most intense marine operating conditions. This model belongs to the new generation MR704 series, renowned for its high torque at low revs, robust construction, economical combustion process, and durability. The MR704LH is one of the most versatile 2.8 L category marine engines, suitable for both recreational and commercial vessels.
The engine is designed on the four-stroke turbodiesel principle, using an electronically controlled direct injection system. This system ensures extremely precise fuel delivery to the cylinders, improves combustion efficiency, and reduces fuel consumption by 10–15% compared to older models. More precise fuel dosing also results in smoother engine operation and lower noise levels. This feature makes the MR704LH an excellent choice for vessels requiring quiet, stable, and comfortable sailing.
The large 2.8-liter displacement ensures powerful torque, which is especially important for marine use. The engine responds quickly to load changes, performs excellently in low rev ranges, and provides sufficient thrust even in rougher seas. The MR704LH is appreciated by captains and yachtsmen who sail in various weather conditions and want a power unit capable of offering high thrust without delay.
The MR704LH achieves high power thanks to an efficient turbocharger and intercooling system. The intercooler reduces the intake air temperature, allowing for improved combustion efficiency and increased overall power without adding extra load to the engine’s temperature. This technology enables better performance over long distances, reduces the risk of overheating, and maintains high performance throughout the sailing regime.
A key feature of this model is the modern dual cooling system, using both fresh and saltwater. The fresh water circuit protects the engine from deposits and corrosion, while the saltwater circuit efficiently cools the heat exchanger. Removable hoses facilitate daily engine maintenance, making servicing simpler and faster even in confined engine spaces.
The MR704LH is designed to minimize the number of external flexible hoses. This solution significantly reduces the likelihood of failures and improves engine longevity. Fewer components also mean easier maintenance and greater reliability on long journeys. For shipowners, this is particularly important as it reduces both operating costs and the risk of technical work.
The engine’s dimensions and weight are designed for easy installation in various types of vessels. Compact dimensions of 850 × 758 × 805 mm and a weight of about 360 kg allow it to be installed even in small engine rooms, maintaining good vessel balance and stability. This makes the MR704LH an excellent choice for boats, RIB-type vessels, 25–40 foot yachts, commercial boats, and workboats.
The MR704LH is also manufactured to meet international emission standards – IMO, BSO, and RCD I. This means that this engine can be used in various European countries and international waters without restrictions. The eco-friendly combustion process and optimized exhaust gas management reduce environmental impact.
The new VM Motori MR704LH Engine (NEW) is valued in the market for its power, reliability, and versatility. Its technologies, engineering solutions, and ease of maintenance make it one of the best choices in 2025 for those seeking a high-quality marine diesel engine for their vessel. This engine is an excellent combination of economy, durability, and high torque, providing a safe, stable, and comfortable sailing experience.
