I-4 V MAX SHO® Series

Mechanical: 175 hp 150 hp Mechanical or Tiller: 115 hp

The In-Line Four V MAX SHO four strokes have achieved the unthinkable—packing signature V MAX SHO hole shot and acceleration into streamlined designs. These 1.8- and 2.8-liter dynamos feature surprising tech packages with 16 valves, double overhead cams and electronic fuel injection—for maximum efficiency and high performance. This makes the I-4 V MAX SHOs perfect for smaller bass, flats and bay boats and other performance hulls. With the addition of 25-inch-shaft options for all of our I-4 V MAX SHO outboards, anglers prowling big waters on multi-species, bay and flats boats have a competitive edge that runs deeper than ever. Find a Demo Tour

Unbeatable Reliability


The I-4 V MAX SHO® 175 and 150 feature a Cowling Drain System and Air Intake Labyrinth System to trap and drain water that enters their cowlings during normal operation.

Convenience & Control

Extra Space 

A four stroke in-line design means there's no need for an external oil tank. That means less weight and more storage room in the boat for tackle and gear.

Ample Charging Power

At 50 amps, the V MAX SHO® 175 and 150 alternators boast an 11 percent increase in charging power over the two stroke 150 HPDI®.

Easy Rigging

I-4 V MAX SHO® outboards feature mechanical controls for easy, convenient rigging with most bass, bay and flats boats, and are compatible with analog, 6Y5 digital or Command Link® gauges.
