MAN D2676 LE 461: Reliable Marine Propulsion Powerhouse The MAN D2676 LE 461, engineered by MAN Truck & Bus AG, is a robust six-cylinder diesel marine engine tailored for primary propulsion in commercial and recreational vessels. Delivering dependable thrust for diverse boating applications, it exemplifies MAN’s commitment to marine-grade engineering, blending high torque with operational efficiency to navigate demanding seaworthy conditions. At its core, the D2676 LE 461 boasts key technical specifications that underscore its prowess: a crankshaft power output of 200 hp (147 kW), derived from a substantial 12.4-liter (12,420 cm³) displacement across six inline cylinders. Optimized for low-speed, high-torque performance, it operates up to a maximum of 1,800 rpm, ensuring smooth power delivery with minimal vibration—ideal for sustained maritime voyages. Performance characteristics shine in its balanced design, featuring advanced thermal management through reinforced cooling pathways and precision-machined components, as evident in its cross-sectional architecture with high-strength alloys for enduring temperature fluctuations. This configuration promotes fuel efficiency during partial-load operations, while its low turbocharging onset minimizes consumption without compromising responsiveness. Tailored for marine rigors, the engine’s corrosion-resistant materials and sealed bearings safeguard against saltwater ingress and humidity, meeting stringent Tier III and IMO emissions standards to curb NOx and SOx outputs. Its modular construction facilitates low-maintenance servicing in remote ports, enhancing uptime and reducing lifecycle costs. Compatibility with diesel-electric hybrid systems further amplifies its versatility, integrating seamlessly with battery-assisted propulsion for optimized energy use. Ideal for medium-sized yachts, patrol boats, or auxiliary power generation on larger ships, the MAN D2676 LE 461 offers a compelling fusion of durability, efficiency, and eco-conscious operation—empowering vessel operators to conquer open waters with confidence and precision.
