📖 Model Background

The Yamaha F225B 4‑stroke outboard was introduced in 2012 and remained in production through 2016 as part of Yamaha’s acclaimed 4.2 L Offshore V6 FourStroke lineup. It’s powered by a 4,169 cc 60° DOHC 24-valve V6 engine featuring Variable Cam Timing (VCT), multi-point EFI, and digital electronic control (DEC), delivering 225 HP at 5,500 RPM. Despite its power, the F225B weighs just 255–261 kg (562–575 lb), thanks to Yamaha’s plasma-fused sleeveless cylinder technology and advanced polymer lower-pan design. It comes standard with features like a 70 A alternator, Thrust Enhancing Reverse Exhaust, power trim & tilt, and compatibility with Shift Dampener System (SDS) props—delivering smooth acceleration, excellent mid-range torque, and rugged offshore performance.
