Craftsman CM4.80 – Marine Diesel Engine 80 HP

Craftsman CM4.80 80 HP – Reliable Mitsubishi-Based Diesel

Overcoming the reliability challenges of offshore cruising, the Craftsman Marine CM4.80 delivers 80 HP at 2500 RPM. Built on a heavy-duty Mitsubishi industrial block, this 4-cylinder engine is a favorite for American sailboat owners and motor-sailers who require a “bulletproof” auxiliary power source. The CM4.80 provides massive low-end torque for motoring through heavy head-seas, offering USA boaters a mechanically simple and robust power plant that is easy to maintain in remote coastal locations from the Atlantic seaboard to the Gulf of Mexico.

Meeting applicable EPA emission standards, the CM4.80 focuses on thermal efficiency and low vibration levels to enhance the environment on deck. The engine features a high-grade freshwater cooling system and a saltwater-resistant heat exchanger, specifically engineered to withstand the corrosive conditions of the American maritime environment. Its high-output alternator and compatibility with various gearbox options ensure that American yacht owners can customize their propulsion system for maximum reliability during long-distance American coastal voyages.
