Yamaha expands the successful V MAX SHO family to include the 115-horsepower segment - where smaller boats and other craft play. And it's every bit a V MAX SHO, compact, lightweight and capable of performance typically associated with two strokes, but with the convenience and quiet of a four stroke. Who could want more?

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. 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.
 
The I-4 V MAX SHO 115 is Yamaha’s fastest 115hp four stroke, ever, with a top speed of nearly 51 mph.* On top of its impressive speed, it features tech unheard of in its class, including a long-track intake system, free-flow exhaust and knock sensor.
KEY FEATURES
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: With 35 amps for the VF90, the alternators produce enough power for battery charging and a range of on-board electronics.

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.
