Solé Mini 23: Reliable Inboard Diesel Propulsion for Compact Vessels The Solé Mini 23 is a compact, inboard diesel engine engineered for dependable marine propulsion in smaller boats. As a three-cylinder powerhouse, it delivers robust performance tailored to recreational and coastal applications, ensuring smooth operation in demanding saltwater environments. Key technical specifications underscore its precision engineering: Manufactured by Solé, this diesel-fueled engine features a 979 cm³ (60.3 in³) displacement, with a bore of 73 mm (2.87 in) and stroke of 78 mm (3.07 in). It produces 20 hp (14 kW) at 3000 RPM per DIN 6270B standards, paired with a 2:1 reduction ratio transmission for optimal torque delivery to the propeller shaft. Weighing just 155 kg (341 lbs), its lightweight yet sturdy construction facilitates easy installation in tight engine compartments without compromising hull balance. In marine-specific applications, the Solé Mini 23 excels through inherent diesel advantages, including superior corrosion resistance to saltwater exposure and reduced vibration via its robust inboard mounting. The engine’s high energy density fuel system promotes exceptional fuel efficiency during extended cruises, while its lower flammability enhances onboard safety compared to gasoline alternatives. Simplified three-cylinder architecture minimizes mechanical complexity, extending service intervals and operational longevity in harsh, humid conditions. Performance-wise, the Mini 23 balances power and efficiency, achieving steady cruising speeds with minimal noise and emissions. Its 3000 RPM maximum ensures reliable low-end torque for maneuvering in confined waters or light towing, while the reduction gear optimizes propeller efficiency for economical operation. Ideal for small yachts, tenders, and recreational day boats like the namesake Solé Mini 23 hull, this engine suits leisure boating where space, reliability, and fuel economy are paramount. It embodies Solé’s commitment to resilient marine engineering, empowering vessel owners with confidence on every voyage. (248 words)
