📖 Model Background

The Yamaha 9.9C 2‑stroke outboard, produced from 2003 to 2006, was built for boaters seeking compact, dependable propulsion. Powered by a 212 cc SOHC two-cylinder engine with CDI ignition and carbureted induction, it delivers a reliable 9.9 HP at around 5,500 RPM. With manual start, tiller steering, and weighing approximately 39–42 kg (87–93 lb), it offered exceptional portability and reliable performance for small inflatables and dinghies. Yamaha included start-in-gear protection and pre-mix lubrication recommendations (100:1 fuel/oil ratio) to enhance safety and engine longevity.
