Bukh A/S Bukh DV10LSME Marine Engine The Bukh A/S Bukh DV10LSME is a robust, inboard single-cylinder diesel engine, meticulously engineered by the Danish manufacturer Bukh A/S for reliable marine propulsion. Introduced in 1971, this legacy design prioritizes simplicity and endurance, making it an ideal choice for compact vessel applications where space and maintenance are paramount. Key technical specifications underscore its straightforward engineering: a 482 cm³ displacement with a square bore and stroke of 85 mm each, delivering a maximum continuous power output of 10.0 DIN hp (7 kW) at a rated speed of 3000 rpm. Weighing just 80 kg (176 lbs) and measuring 844 mm in length, 538 mm in width, and 410 mm in height, its lightweight, compact footprint facilitates seamless installation in confined engine compartments. Naturally aspirated and fueled by diesel, it employs an S-drev direct-drive transmission system, ensuring efficient power transfer to the propeller shaft without the complexity of multi-gear setups. Tailored for harsh marine environments, the DV10LSME boasts corrosion-resistant materials and seals that withstand saltwater exposure, while its single-cylinder configuration minimizes mechanical components for enhanced reliability and ease of servicing—even in remote offshore locations. Diesel’s high energy density promotes superior fuel efficiency, enabling extended operational ranges with low lubrication demands and global fuel availability, which translates to reduced lifecycle costs. Performance-wise, this engine excels in low-thrust scenarios, providing steady torque for maneuvering at speeds of approximately 6–8 knots (depending on hull and gearing), though its natural aspiration limits high-speed or heavy-load capabilities in choppy conditions. Its 80 kg-to-10 hp weight-to-power ratio emphasizes efficient, dependable operation over raw performance. Ideally suited for small vessels such as dinghies, tenders, auxiliary sailboat systems, or historical yacht restorations, the Bukh DV10LSME embodies time-tested marine engineering—balancing durability, simplicity, and cost-effectiveness for inshore and leisure boating demands.
