Nanni 2.45 HE Eco S: Compact Power for Marine Propulsion The Nanni 2.45 HE Eco S, engineered by Nanni Industries SAS, is a high-efficiency inboard diesel engine designed for reliable propulsion in small marine vessels. This 4-stroke, 4-cycle, twin-cylinder powerhouse delivers 10 horsepower (7 kW) at the crankshaft, making it an ideal choice for boaters seeking dependable performance without compromising on efficiency or environmental responsibility. Key technical specifications underscore its robust engineering: a displacement of 479 cm³ ensures optimal power output, while the lightweight 129 kg (284 lbs) dry weight facilitates straightforward installation. Measuring 803 mm in length, 503 mm in width, and 655 mm in height, its compact footprint suits tight engine bays. The engine achieves a maximum operating speed of 3,600 RPM, paired with an S-Drev transmission featuring a 2.2:1 reduction ratio for precise torque delivery. Freshwater cooling via a closed-loop system protects against corrosion in harsh marine environments, complemented by an electric start system (ENS-7i) for effortless ignition. Powered by diesel fuel, it operates as an inboard drive, with no specified minimum RPM for versatile low-speed maneuvering. Tailored for marine applications, the Nanni 2.45 HE Eco S excels in durability and sustainability. Its “HE Eco S” designation highlights eco-friendly optimizations, including reduced emissions and superior fuel efficiency to meet stringent environmental regulations. The robust construction withstands saltwater exposure, vibrations, and constant humidity, while the 4-stroke design promotes longevity and quieter operation compared to 2-stroke alternatives. Low maintenance demands arise from the simplified twin-cylinder configuration, minimizing downtime during extended voyages. Performance-wise, this engine offers balanced characteristics: smooth, vibration-free operation at high RPMs for responsive acceleration, coupled with low fuel consumption that cuts operating costs. It provides quiet, efficient cruising, enhancing onboard comfort without sacrificing power. Ideal for day cruisers, tenders, small yachts, and recreational coastal vessels, the Nanni 2.45 HE Eco S combines compact versatility with eco-conscious reliability, empowering mariners to navigate with confidence and minimal ecological footprint.
