Solé Mini 28: Reliable Inboard Diesel Propulsion for Compact Vessels The Solé Mini 28 is a robust, inboard diesel engine engineered for dependable marine propulsion in small to medium-sized boats. Originating from a proven 1975 design by Solé Diesel, a specialist in marine power systems, this engine delivers consistent performance through its horizontally opposed twin-cylinder configuration, ensuring smooth operation and minimal vibration even in challenging sea conditions. Key technical specifications underscore its practicality: It produces 28 horsepower (20.6 kW) with a displacement of 1,346 cm³, optimized for efficient power delivery at a minimum operating speed of 2,500 RPM. Weighing just 248 kg, the compact unit features electric starting for effortless ignition in damp or remote environments, eliminating the need for manual cranking. As a diesel-fueled inboard drive, it employs a durable combustion process that enhances torque output per liter of fuel, with a dry weight that facilitates straightforward installation in tight engine compartments. In marine applications, the Solé Mini 28 excels with marine-specific benefits tailored to saltwater endurance. Its inboard placement lowers the vessel’s center of gravity, promoting superior stability and handling during coastal passages or light chop. The diesel architecture provides inherent advantages, including high fuel efficiency for extended range without frequent refueling, reduced risk of fouling or overheating in humid conditions, and corrosion-resistant construction implied by Solé’s marine expertise. The twin-cylinder layout further minimizes component stress, contributing to low maintenance demands and exceptional longevity compared to gasoline alternatives. Performance-wise, the engine offers balanced torque for reliable low-speed maneuvering and steady cruising, though its modest output suits displacement hulls rather than high-speed planing. Ideal for classic sailboats, tenders, or small cruisers engaged in leisurely coastal voyages or inland waterways, the Solé Mini 28 combines timeless simplicity with proven reliability—perfect for budget-conscious operators seeking hassle-free propulsion without modern emissions complexities.
