📖 Model Background

The Yamaha 300 HP FL300B V6 4-stroke debuted as part of Yamaha’s next-generation 4.2 L DOHC V6 series (first introduced in the early 2010s) designed for offshore performance. With a 60° V6, 24-valve, DOHC powerhead and a displacement of 4,169 cc, it delivers 300 hp at 5,500 RPM while weighing around 260–268 kg—making it noticeably lighter than earlier generations. It features Yamaha’s Variable Cam Timing (VCT), drive-by-wire electronic throttle, and Digital Electronic Control, all aimed at improving mid-range torque, responsiveness, and maneuverability (enhanced by Thrust-Enhancing Reverse Exhaust in DEC models). The FL300B quickly became a top choice for serious offshore anglers and cruisers thanks to its strong power-to-weight ratio and advanced marine technology.
