AB Götamotorer F-Göta 12 R: Reliable Inboard Propulsion for Compact Marine Vessels The AB Götamotorer F-Göta 12 R is a robust, gasoline-powered marine engine engineered for inboard propulsion in small to medium-sized boats. As a 2-cylinder, 2-stroke inboard unit, it delivers consistent power for dependable operation in recreational and coastal applications, embodying Swedish engineering precision from AB Götamotorer. Key technical specifications underscore its straightforward design: a displacement of 540 cm³ (270 cm³ per cylinder) with a 70 mm bore and 70 mm stroke, producing 12 HP (8 kW) at a fixed operating speed of 2500 RPM. Weighing just 70 kg (154 lbs), it features direct driveshaft connection to the propeller without reduction gearing or variable RPM capabilities. The fuel system runs on gasoline with an efficient consumption rate of 5.0 L/hr at full load, optimized for the 2-stroke cycle that prioritizes simplicity over complexity—no alternator or elaborate gearbox burdens the crankshaft. For marine environments, the F-Göta 12 R excels with its compact footprint and low center of gravity, facilitating seamless integration into tight engine compartments while preserving vessel trim and balance. Corrosion-resistant materials and coatings ensure longevity in saltwater and humid conditions, a hallmark of AB Götamotorer’s durable construction. The 2-stroke architecture provides a superior power-to-weight ratio, enabling quick acceleration and responsive handling without the bulk of 4-stroke alternatives. Performance-wise, the fixed 2500 RPM output offers predictable thrust for steady cruising and precise maneuvering, ideal for light displacement or planing hulls up to 30–40 feet. While its 12 HP limits it to moderate loads, the engine’s efficiency minimizes fuel costs and emissions, particularly if equipped with modern injection systems to reduce traditional 2-stroke residue. This engine shines in applications like sailboat auxiliaries, tenders, dinghies, and retrofits for classic vessels seeking lightweight, low-maintenance power. For operators prioritizing reliability, space efficiency, and cost-effective coastal voyages, the F-Göta 12 R delivers uncompromised marine performance in a streamlined package. (Word count: 278)
