To start, SHO stands for “super high output.” These outboard motors will get you zooming across the water at efficient speeds you've never experienced before.

A single-overhead-camshaft design with four valves per cylinder and 1.8-liter displacement make the I-4 V MAX SHO 90 a class leader in torque, top speed and efficiency. Even still, it's one of the quietest 90-horsepower outboards on the water. That makes for some pretty stealthy fishing.

In 2009, the world of high-performance outboarding changed with the introduction of the 4.2L V MAX SHO. Here was an outboard that was light weight with the speed and acceleration that bass boaters had been demanding, but in a high performance four-stroke engine platform.

Yamaha's line of VMAX SHO® are built with efficiency in mind. From their super high-performance designs, impressive torque curve, and excellent hole shot acceleration, V MAX SHO® provides an improved experience out on the water versus Yamaha's standard line of outboards.

Some SHO models offer a bigger power advantage over the "standard" model than others. Some require 89 octane fuel (for optimum performance) compared to 87 octane for the standard models. 89 octane fuel is required for some, but not all, of the SHO models.

Yamaha Vmax has a top speed of 220 kmph.

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.

Twin test: Ducati XDiavel vs Yamaha V-Max Here's our verdict... "Yamaha's VMax is still the king of the strip, still the ultimate muscle bike, and capable of destroying a rear tyre in one day's hard riding. It's far from a bad bike, but the new Ducati XDiavel makes it feel prehistoric.

The FX HO reaches a top speed of 62.6 MPH.

It's loaded with features and its 1.8lt supercharged engine delivers scintillating performance.
