Bukh A/S Bukh DV36SME Marine Diesel Engine The Bukh A/S Bukh DV36SME is a reliable, inboard-mounted diesel engine engineered for marine propulsion, delivering steadfast performance in demanding nautical environments. As a 3-cylinder, naturally aspirated SSOH (square stroke-over-bore) diesel powerplant, it excels in small to medium vessels where simplicity and durability are paramount. Key technical specifications underscore its robust design: a displacement of 1,447 cc (bore and stroke both 85 mm) provides balanced power output, with a maximum continuous rating of 36.0 hp (26.0 kW DIN) at a minimum operating speed of 3,600 rpm. Weighing just 310 kg (683 lbs), it measures 1,097 mm in length, 608 mm in width, and 850 mm in height, facilitating seamless integration into space-constrained hulls. Fuelled by diesel for superior energy density and longevity, the engine features a direct-drive S-drev transmission, minimizing parasitic losses and ensuring efficient torque transfer to the propeller shaft. Introduced in 1974 with refinements in 1977, its proven architecture prioritizes mechanical simplicity over electronic complexities. For marine applications, the DV36SME offers distinct advantages, including corrosion-resistant materials to combat saltwater exposure and enhanced vibration dampening via its inboard configuration and fixed tubular exhaust systems. Its naturally aspirated setup enables reliable cold starts in sub-zero conditions, ideal for polar or temperate operations, while the lightweight construction reduces vessel draft and enhances maneuverability without compromising stability. Performance-wise, the engine balances fuel efficiency with responsive power delivery, achieving optimal cruising speeds with minimal consumption—perfect for extended voyages. The square bore-stroke ratio optimizes thermal efficiency and reduces friction, contributing to low maintenance demands and extended service intervals in remote at-sea scenarios. Ideal for auxiliary propulsion in sailboats, dinghies, small fishing craft, or lifeboats, the Bukh DV36SME embodies timeless engineering reliability. Though it lacks modern emissions controls or electronic fuel injection, its unyielding dependability makes it a favored choice for mariners valuing proven, no-fuss performance over high-output sophistication.
