Bukh DV18ME Marine Diesel Engine: Reliable Inboard Propulsion The Bukh DV18ME, manufactured by Bukh A/S, is a compact, twin-cylinder inboard diesel engine engineered for dependable marine propulsion in small to medium-sized vessels. Since its introduction in 1977, this timeless design has powered countless boats with robust efficiency, leveraging naturally aspirated diesel technology for smooth, vibration-dampened operation in demanding saltwater environments. Key technical specifications underscore its practicality: a displacement of 851 cm³ from a 85 mm bore and 75 mm stroke configuration, delivering a maximum continuous power output of 18.0 hp (13 kW) per DIN standards. Weighing just 118 kg (260 lbs), it measures 783 mm in length, 472 mm in width, and 513 mm in height, making it ideal for confined engine bays. The engine operates on diesel fuel with a typical RPM range of 1,100–3,600, emphasizing low-end torque for efficient cruising without the complexity of turbocharging. Marine-specific benefits shine through its corrosion-resistant construction, designed to endure humidity, vibrations, and thermal extremes inherent to offshore use. The simplified natural aspiration system minimizes maintenance demands, reducing downtime and servicing costs—essential for remote voyages or owner-operated fleets. Diesel efficiency translates to superior fuel economy, extending range on long passages while lowering operational expenses. Performance-wise, the DV18ME excels in balanced power delivery, providing reliable thrust at displacement speeds up to 3,600 RPM without excessive noise or emissions, aligning with modern eco-conscious boating. Its lightweight footprint enhances vessel trim and maneuverability, while inherent durability ensures longevity under heavy loads. Ideal for sailboats, tenders, cruisers, and small commercial craft, the Bukh DV18ME offers versatile, low-maintenance propulsion that blends classic engineering with practical marine reliability—perfect for enthusiasts restoring vintage hulls or seeking cost-effective inboard solutions.
