📖 Model Background

The Yamaha 225G 4‑stroke outboard, produced from 1998 to 2003, was part of Yamaha’s first-generation 3.4 L V6 FourStroke lineup. Powered by a 3,352 cc DOHC 24‑valve V6 engine with multi-point EFI, it delivered 225 HP at 5,500 RPM while maintaining a dry weight around 283–289 kg—delivering excellent power-to-weight balance. Designed for inshore and offshore performance, the 225G featured digital electronic control (DEC), power trim & tilt, and compatibility with Shift Dampener System (SDS) props.
