Ford Lehman 2726TG Marine Engine: Reliable Propulsion for Demanding Seas The Ford Lehman 2726TG is a robust inboard diesel engine from the renowned Ford Lehman series, engineered specifically for marine propulsion in boats and vessels. Delivering up to 250 horsepower, this six-cylinder powerhouse provides dependable, torque-rich performance tailored to the rigors of saltwater environments, ensuring smooth operation and extended service life. Key technical specifications underscore its engineering excellence. With a displacement of 5,950 cm³ (5.95 liters), the engine features a bore of 105 mm and stroke of 115 mm, optimized for balanced power delivery. Its high compression ratio of 15.45:1 promotes efficient diesel combustion via direct injection, while Tier 2-compliant emissions systems minimize environmental impact. The inline six-cylinder configuration—common in marine diesels—enhances torque smoothness, paired with a durable cast-iron block resistant to corrosion and thermal stress. Cooling is managed through an advanced water-cooled intercooler, supporting turbocharged efficiency, and it integrates seamlessly with 3- or 4-speed marine gearboxes for precise thrust control. In marine applications, the 2726TG excels with benefits like superior fuel economy, thanks to its high compression and diesel efficiency, reducing operational costs on long passages. Its inboard mounting minimizes hull vibrations and noise, improving onboard comfort, while the compact power-to-weight ratio allows for agile handling without excessive mass. Reliability is paramount, with corrosion-resistant components and extended maintenance intervals designed to withstand harsh conditions like saltwater exposure and variable loads. Performance-wise, the engine shines in mid-range RPMs, offering strong low-end torque for quick acceleration and sustained cruising speeds, ideal for displacement hulls up to 50 feet. This versatility makes it a top choice for recreational yachts, fishing trawlers, and commercial workboats, where dependable propulsion ensures safe, efficient voyages.
