V MAX In-line 4 90 hp 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.

Super High Output four- SHO stands for Super High Output four-stroke technology. The old 3.3L engine has been upgraded to a 4.2L engine. The outboard is 34 pounds lighter than the V MAX Series II two-stroke engine it replaces in the Yamaha product line. No other outboard with the same horsepower is lighter, in fact.

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.

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.

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. The Yamaha V MAX SHO boasts its iconic four-stroke fuel economy, which is much quicker than a classic two-stroke.

Yamaha Vmax has a top speed of 220 kmph.

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.

SHO is a stud, exactly zero concerns running in salt. No issue with a SHO in salt water.
