2022 Yamaha F250B – 25″ Shaft brings new levels of convenience and control to a proven performer. The next-generation 4.2-litre F250 Offshore outboard combines a high-performance, big block V6 featuring outstanding power and fuel efficiency with the availability of Yamaha-exclusive built-in Digital Electric Steering and Thrust Enhancing Reverse Exhaust.

Key Features

• 4.2-litre big bore displacement: By using a highly advanced, thermally applied plasma fusion process on the cylinder walls, 2022 Yamaha F250B – 25″ Shaft’s new line of V6 Offshore outboards have no conventional steel cylinder sleeves, yet the cylinder walls are 60% harder than steel. That means larger cylinder bores for increased displacement, resulting in more power and torque, without increasing outer cylinder dimensions. It also results in dramatically lighter weight, better cooling, and “micro-textured” cylinder walls that help decrease friction loss, and further increase performance and enhance reliability.
• Lightest weight in class: From the top of the cowling to the tip of the prop shaft, every ounce of weight savings has been realized for maximum performance without sacrificing durability. There’s even a new advanced polymer composite lower engine pan that lowers weight and increases corrosion resistance.
• Throttle response and acceleration: F250B – 25″ Shaft has Variable Camshaft Timing system advances and retards the angle of the intake camshaft to dramatically increase power and throttle response in the low- and mid-rpm ranges. This feature helps Yamaha’s new 4.2-litre big-bore V-6 Offshore Outboard to deliver awesome hole shot and mid-range acceleration you have to feel to believe.
