📖 Model Background

The Yamaha 115 HP FL115B (often designated F115B) debuted in 2014 as a second-generation 115 HP inline‑4, replacing the long-running F115A introduced in 1999. The engine features a larger 1,832 cc DOHC EFI powerhead yet weighs ~14 kg less, thanks to a lighter bracket, cowling, and composite lower unit. Yamaha engineers also upgraded vibration damping with rubber mounts and a harmonized flywheel. The result: a quieter, smoother, and more responsive outboard with stronger mid-range torque, better fuel efficiency, and top-in-class power-to-weight, making it a popular pick for versatile boats like pontoons, cruisers, and inflatable tenders.
