2016 Yamaha VF250XA VMAX SHO Outboard NEW

More details

The four stroke  Yamaha VF250XA VMAX SHO Outboard offers all the advantages of a two stroke in a clean burning, fuel efficient four stroke. It’s a level of performance that pro anglers have always wanted on the tournament circuit. And it’s officially put two strokes on notice.

A MotorBoating Best Of in 2009 and 2010, the Four Stroke V MAX SHO® features:

Lightning-Fast Hole Shot: The V MAX SHO® has a 4.2L big-bore design that shoots it out of the hole up to 13% faster than its two stroke competitors. Its variable camshaft timing increases throttle response in the low and midranges, resulting in unbelievable acceleration, top-end and midrange punch.

Brute Strength: Its 4.2L big-bore design gives the V MAX SHO® class-leading displacement and power-to-weight ratio.

Smart Innovations: Micro-textured cylinder walls and a new intake system greatly improve fuel economy. In fact the V MAX SHO® boasts up to 12% better fuel economy than competitive two strokes, and is C.A.R.B. 3-Star Rated for Ultra Low Emissions
  • Cleaner Fuel: All V MAX SHO® outboards utilize a large, on-engine water separating fuel filter with a water sensor. Used in conjunction with Yamaha’s 10-Micron Water Separating Fuel Filter, it helps separate water and contaminants from the fuel before they can reach the outboard’s other filters and fuel injectors.
  • Outstanding Fuel Economy: The 4.2 liter big-bore V MAX SHO® four stroke outboard averages 12% better fuel economy throughout the RPM range than our venerable 3.3 liter direct-injected 250HP 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 help ensure the precise amount of air and fuel necessary for optimum power and fuel efficiency. The reduction in friction from the Micro-Textured Cylinder Walls further adds to this outboard’s amazing fuel economy.
  • Low and Midrange Throttle Response: Yamaha’s Variable Camshaft Timing system advances and retards the position 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 liter big-bore V MAX SHO® four stroke provide awesome hole shot and mid-range acceleration you have to feel to believe.
  • 4.2 Liter Big-Bore Displacement: 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, further increasing performance and enhancing reliability.
  • Responsive Power: 4.2 liters 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.
  • Smart Design: Yamaha’s exclusive In-Bank™ Exhaust System exits downward through the center of the engine between the “V” of the cylinders, rather than on the exterior side. This increases combustion efficiency for more power and torque, and also provides for a more compact shape.
  • Smooth and Quiet: 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.
