Description
Yamaha 9.9 outboard electric 2013 Long shaft with control box Engine Specs Displacement: 212cc, 2-cylinder in-line SOHC Bore x Stroke: 56mm x 43mm Full throttle range: 5,000–6,000 RPM Weight (long shaft): ~40–42 kg Gear ratio: 2.08:1 Oil capacity: 0.8 litres Fuel tank: Separate 12-litre tank Will consider swap for a short shaft ✅ What Owners Love Fuel efficiency — A cruising loop at mixed throttle settings showed an average burn of just 1.8 litres/hour, giving around 6.6 hours from a 12-litre tank TradeABoat — excellent economy for a 9.9hp motor. Torque & performance — The twin-cylinder four-stroke develops significantly more torque than comparable two-strokes, easily outperforming them even with the added weight. TradeABoat Quiet & clean — Owners consistently praise the quieter running and better fuel efficiency compared to 2-strokes, and there's no more mixing oil with fuel. Stufishing Handy flush system — The Yamaha 9.9 features a flushing pipe that lets you attach a garden hose and flush the cooling system without even starting the engine Stufishing — very convenient after saltwater use. Build quality — With a little TLC, this Yamaha should give at least a decade of reliable power. TradeABoat Made in Japan is a strong quality indicator. ⚠️ Known Downsides Weight — At 43kg, some owners find it a struggle to lift onto the transom, and a few have downgraded to a smaller 6hp just to avoid the physical effort. Stufishing Side storage issue — Four-strokes don't like being stored on their side — oil can get into the cylinders causing hydrolock, making starting very difficult. The Hull Truth Always store upright if possible. 🏆 Overall Verdict The 2013 Yamaha F9.9 4-stroke long shaft is widely regarded as one of the best small outboards available — reliable, fuel-efficient, quiet, and built to last.
