2025 Yamaha Outboards VF250 VMAX SHO

The Yamaha V MAX SHO. Quicker, stronger, smarter and lighter...outperforming two strokes on hole shot, displacement, fuel economy and weight.

Features may include:

• By using a highly-advanced thermally-applied plasma fusion process on the cylinder walls, the V MAX SHO has 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 the "micro-textured" cylinder walls help reduce friction loss, further increasing performance and enhancing reliability.

• 4.2 litres of class-leading displacement teams with individual intake and exhaust camshafts to provide more precise valve timing control with fewer moving parts than conventional rocker arm systems for increased reliability. This superior design also allows for use of 4 valves per cylinder which exchange intake and exhaust gases more efficiently for responsive power and increased fuel economy. Intake valves are 14% larger and exhaust valves are 10% larger than our 3.3L DOHC system.

• Yamaha's 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 MAX SHO four stroke provide awesome hole shot and mid-range acceleration you have to feel to believe.

• The Yamaha V MAX SHO is faster than even the vaunted V MAX Series 2 that it replaces. This means four stroke smoothness, convenience, and reliability; with top speed better than that of our direct-injected two-stroke of comparable horsepower.

• Engine exhaust is routed through a maze before exiting above the waterline through the idle exhaust relief outlet, for unbelievably smooth and quiet operation. A mufflerless design creates a more direct exhaust flow and a pleasing sound of power at idle.

• Averaging 12% better fuel economy throughout the RPM range than our venerable 3.3-litre direct-injected V MAX Series 2 two stroke. All air entering the engine block of the V MAX SHO is routed through a single 75mm electronically controlled throttle valve. Working in concert with the Precision Multi-Point Fuel Injection System, they together help ensure the precise amount of air and fuel necessary for optimum power and fuel efficiency.
