📖 Model Background

The Yamaha F115C 4‑stroke outboard was produced from 2003 to 2006 as the first-generation DOHC inline‑4 in Yamaha’s mid-HP FourStroke lineup. Powered by a 1.8 L (1,832 cc) DOHC EFI engine with a 35 A alternator, it delivered smooth 115 HP performance while weighing just 171–175 kg—making it one of the lightest 115 HP four-strokes available. During its run, Yamaha refined the EFI components and exhaust design to improve fuel efficiency and reliability.
