📖 Model Background

The Yamaha F225C 4‑stroke V6 outboard was produced from 2003 to 2009 as a performance-focused variant of Yamaha’s 3.4 L FourStroke V6 lineup. It features a 3,352 cc 60° DOHC V6 engine with Variable Cam Timing (VCT) and multi-point EFI, delivering 225 HP at 5,500 RPM while maintaining a dry weight around 283 kg—making it one of the lightest in its class. Introduced for long‑shaft (20") transoms, the F225C incorporates unique features like a lower-mounted powerhead, exclusive ECM tuning, longer intake manifold, and a new piston design for sharper throttle response. Equipped with digital electronic control (DEC), shift-dampener (SDS) prop compatibility, and thrust-enhancing reverse exhaust, it became a top choice for ski-boat racers and offshore anglers seeking responsive performance and high-speed agility.
