Ford Lehman 2726TM Marine Propulsion Engine The Ford Lehman 2726TM is a robust, inboard diesel marine engine engineered for reliable boat propulsion, delivering consistent power to a wide range of vessels navigating coastal and offshore waters. Renowned for its Ford-derived heritage adapted by Lehman for marine duty, this engine excels in demanding environments where durability and efficiency are paramount. Key technical specifications include a 6-cylinder in-line configuration with a displacement of 5,950 cm³ (5.95 L), achieved through a balanced bore of 105 mm and stroke of 115 mm. Its high compression ratio of 15.45:1 optimizes combustion efficiency, while the inboard design integrates seamlessly with direct-drive or gear reduction transmissions. Although exact power output, weight, and RPM ratings are model-dependent, the 2726TM typically produces mid-range horsepower suitable for sustained marine operations, with fuel consumption minimized for extended voyages. In marine applications, the 2726TM offers distinct benefits, including enhanced thermal efficiency that reduces fuel burn and emissions—critical for eco-conscious operators complying with international maritime regulations. The inline cylinder layout minimizes vibration and noise, ensuring smooth, quiet running that enhances onboard comfort and facilitates clear communication during maneuvers. Its rugged construction, leveraging diesel-engine longevity, withstands corrosive saltwater exposure, corrosion, and variable loads, resulting in lower total ownership costs through reduced maintenance intervals and downtime. Performance-wise, the engine provides torque-rich output for efficient planing, towing, and displacement hull propulsion, maintaining stability in choppy seas without excessive throttle demand. This versatility makes it ideal for mid-sized yachts, fishing trawlers, workboats, and pleasure crafts, from leisure cruisers to light commercial operations like charter services or research vessels. Overall, the Ford Lehman 2726TM embodies proven marine engineering, blending power, economy, and reliability to support safe, efficient seafaring across diverse hull types and missions.
