I-4 V MAX SHO Series

The Yamaha In-Line Four V MAX SHO four strokes have achieved the unthinkable—packing signature V MAX SHO hole shot and acceleration into streamlined designs. This powerful family now includes the all-new I-4 V MAX SHO 90, which packs the biggest punch of any 90-horse on the water. Overall, this series of 1.8- and 2.8-liter dynamos features a surprising tech package with 16 valves, single- or 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 option of a 25-inch shaft 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.
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.
With 50 amps for the I-4 V MAX SHO 175 and 150, and 35 amps for the 115 and 90, their alternators produce enough power for battery charging and a range of on-board electronics.
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.
