Yamaha 60FEDOS Marine Outboard Engine The Yamaha 60FEDOS is a robust, gasoline-powered 2-stroke outboard engine engineered for reliable boat propulsion in demanding marine environments. Delivering 60 horsepower (44 kW) of crankshaft power, this compact powerhouse is tailored for small to medium vessels, ensuring seamless integration with various hull designs for enhanced maneuverability and efficiency. Key technical specifications underscore its engineering excellence: a 3-cylinder configuration with 849 cm³ displacement provides balanced power delivery, while the 12:28 reduction ratio amplifies torque for superior low-end thrust. Weighing just 95.5 kg (210 lbs) and featuring a 381 mm shaft length, it maintains an operating RPM range of 4,500–5,500, offering a 1,000 rpm bandwidth for smooth acceleration. Equipped with an electric start system, it eliminates manual cranking hassles, and its marine-grade aluminum alloy construction resists corrosion from saltwater exposure. In marine applications, the 60FEDOS excels with its lightweight profile, which reduces overall vessel displacement and improves fuel economy without compromising stability—critical for navigating choppy waters or shallow drafts. The 2-stroke design delivers high power-to-weight efficiency, minimizing operator fatigue during extended outings, while accessible service points for fuel, oil, and electrical systems facilitate straightforward maintenance in remote anchorages. Performance-wise, the engine’s torque-rich gearing enables rapid planing and responsive handling against wind and current resistance, with peak output optimized for dynamic RPM operation. This results in consistent thrust for activities demanding quick bursts, such as towing or tight maneuvers. Ideal for recreational pursuits like water skiing, wakeboarding, or day cruising on dinghies and runabouts, the Yamaha 60FEDOS combines Yamaha’s renowned durability with user-centric features, making it a versatile choice for boaters seeking spirited, low-maintenance propulsion in coastal or inland waters.
