Perkins M130C Marine Diesel Engine The Perkins M130C is a robust, inboard diesel engine engineered for reliable marine propulsion, delivering consistent power to drive vessels through demanding seaworthy conditions. As a naturally aspirated, six-cylinder inline powerplant, it combines Perkins’ renowned durability with efficient performance, making it a staple for mid-sized marine applications. Key technical specifications underscore its engineering prowess: It produces 135 horsepower (99 kW) of crankshaft power at 2,600 RPM, with 130 horsepower (95 kW) available at the propeller shaft after transmission losses. The 6-liter (6,000 cm³) displacement features a 100 mm bore and 127 mm stroke for enhanced low-end torque, ideal for marine loads. Weighing 595 kg (1,311 lbs) and measuring 1,398 mm in length, 645 mm in width, and 810 mm in height, its compact footprint suits constrained engine rooms. Freshwater jacket-water cooling ensures optimal thermal management, while an electric starter facilitates quick, dependable ignition. Operating on diesel fuel with natural aspiration, it minimizes complexity without turbochargers, promoting longevity in saline environments. For marine-specific benefits, the M130C excels in corrosion-resistant construction and vibration-dampening inline configuration, reducing structural stress on hulls during prolonged voyages. Its freshwater cooling system prevents biofouling and overheating in humid, saltwater exposures, extending service intervals compared to seawater-cooled alternatives. Low-maintenance design—free of intricate forced-induction components—lowers operational costs and downtime, while the efficient undersquare bore/stroke ratio optimizes fuel economy for extended range. Performance-wise, the engine delivers smooth, balanced operation at its rated 2,600 RPM, providing ample torque for precise maneuvering in harbors or adverse weather, with a high power-to-weight ratio for agile handling without excess mass. Ideal for medium-sized yachts, fishing trawlers, and small commercial workboats, the Perkins M130C offers versatile, cost-effective propulsion that prioritizes reliability and efficiency on the water.
