📖 Model Background

The Yamaha 15C 2‑stroke outboard was produced from 2003 through 2006 as part of Yamaha’s compact two-stroke line. Powered by a 363 cc SOHC twin-cylinder engine with CDI ignition and a carburetor fuel system, it delivered a smooth and reliable 15 HP at around 5,000 RPM. Weighing approximately 41–44 kg (90–97 lb), the 15C offered both manual and electric start options, with tiller or remote steering availability. Its lightweight build, dependable oil-injection system, and low-noise exhaust design made it a popular choice for inflatables, dinghies, and small fishing boats.
