📖 Model Background

The Yamaha F300B 4‑stroke outboard, part of Yamaha’s next-generation 4.2 L V6 FourStroke lineup, was produced from around 2010 through the mid‑2010s. It delivers a powerful 300 HP at 5,500 RPM from its 4,169 cc 60° DOHC V6 engine with Variable Cam Timing (VCT) and fuel injection—while maintaining a dry weight of just 260–268 kg. Notable features include plasma-fused sleeveless cylinder walls (making them ~60 % harder than steel), digital electronic control (DEC), power trim & tilt, Thrust Enhancing Reverse Exhaust, and the lightweight Saltwater II SDS propeller. These advancements combined for exceptional acceleration, fuel efficiency, quiet operation, and precise handling—earning the F300B a reputation as one of the lightest and most advanced 300 HP outboards of its time.
