AB Götamotorer F-Göta 12 VR: Compact Inboard Marine Propulsion The AB Götamotorer F-Göta 12 VR is a robust, gasoline-fueled 2-stroke inboard marine engine engineered for reliable propulsion in small vessels. Produced by the specialized Nordic manufacturer AB Götamotorer, this twin-cylinder powerhouse delivers consistent performance tailored to demanding aquatic environments, ensuring smooth operation without the complexity of multi-gear systems. Key technical specifications underscore its efficient design: It produces 12 horsepower (8 kW) at a fixed crankshaft speed of 2,500 RPM, with a displacement of 540 cm³ via a square bore-and-stroke configuration of 70 mm x 70 mm. Weighing just 70 kg (154 lbs), the engine features a direct-drive setup, eliminating reduction gearing for simplified mechanics. As a 2-stroke cycle unit, it employs a straightforward oil-gasoline mixing system for lubrication, achieving fuel consumption of approximately 5.0 liters per hour—ideal for extended operations. In marine applications, the F-Göta 12 VR excels with its lightweight, compact footprint, enhancing vessel stability by lowering the center of gravity and minimizing engine bay demands. Its durable crankshaft and pistons are built to endure vibrations, saltwater corrosion, and harsh conditions, providing unwavering reliability for emergency or recreational use. Performance-wise, the fixed-speed operation yields high torque at low RPMs, promoting steady cruising and fuel efficiency while reducing maintenance through fewer moving parts and no transmission losses. This engine shines in niche scenarios, such as primary propulsion for tenders, lifeboats, and coastal fishing craft, or auxiliary power in sailboats navigating inland waterways. Its simplicity and cost-effectiveness make it a go-to choice for operators prioritizing dependability over variable throttling, offering a balanced solution for small-hull versatility in moderate sea states.
