📖 Model Background

The Yamaha F80B 4‑stroke outboard was produced from around 2004 to 2012 and stands out in Yamaha’s mid‑power FourStroke lineup. Powered by a 1.8 L SOHC inline‑4 EFI engine shared with the F75 and F90, it produces a smooth 80 HP with strong torque and clean emissions. Notable for its lightweight design and 35 A alternator, the F80B delivers reliable performance and practical fuel economy. The model also features improved exhaust routing (labyrinth design) that reduces noise and vibration, making it a popular choice for recreational and fishing boats seeking quiet, dependable cruising power.
