AB Götamotorer F-Göta 18 RE: Reliable Inboard Propulsion for Compact Marine Vessels The AB Götamotorer F-Göta 18 RE is a robust, gasoline-powered inboard marine engine engineered for dependable boat propulsion. Rooted in Swedish manufacturing heritage, this 4-stroke engine embodies simplicity and durability, delivering consistent power for small to mid-sized vessels navigating coastal or inland waters. Key technical specifications include a compact 3-cylinder horizontally opposed (flathead) configuration with a displacement of 710 cm³, achieved through a symmetric 70 mm bore and 70 mm stroke for balanced operation. It produces 18 horsepower (13 kW) at a fixed operating speed of 2000 RPM, utilizing gasoline fuel for straightforward refueling and ignition. The air-cooled system eliminates the need for liquid coolant, while the manual transmission provides direct mechanical control without hydraulic complexities. Weighing in at a lightweight profile (exact figures unavailable), it features no reduction gear, optimizing it for fixed-pitch propeller setups. In marine environments, the F-Göta 18 RE excels with its inboard mounting, which lowers the vessel’s center of gravity for enhanced stability and reduced hull penetration requirements. The air-cooling design resists seawater corrosion and fouling, minimizing maintenance risks in remote or tropical conditions, while the single-carburetor setup ensures reliable starts and longevity with basic servicing. These attributes make it a cost-effective choice, avoiding the infrastructure demands of diesel systems. Performance-wise, the engine offers steady torque delivery at its optimized 2000 RPM, ideal for efficient cruising without variable-speed variability—though this limits fine maneuvers like slow-speed docking. It prioritizes fuel economy through its small displacement and fixed operation, suiting applications where oversized propellers can maximize propulsion efficiency. This engine is perfectly suited for tenders, fishing boats, cabin cruisers, or auxiliary generator duties on vessels carrying 1–4 passengers. For operators valuing operational simplicity, Swedish-engineered resilience, and low upfront costs over high-performance versatility, the F-Göta 18 RE stands as a timeless solution in marine propulsion.
