Yamaha Further Defines Fresh Water Performance with V MAX SHO® 115

Posted by admin on February 14, 2015


Super High Output Four-Stroke Series Expands to Include Smaller Boats

Yamaha Marine Group has introduced V MAX SHO for smaller craft, the V MAX SHO 115, an outboard that will bring all the attributes of the V MAX SHO to a much larger group of boaters and anglers.

"The V MAX SHO 115 is compact, light weight and capable of performance typically associated with two strokes, but with the convenience, fuel efficiency and quiet operation of a four stroke," said Ben Speciale, President, Yamaha Marine Group. "Now owners of smaller boats can enjoy the benefits of the V MAX SHO family."

The V MAX SHO 115 arrives on the heels of the successful V MAX SHO 250, V MAX SHO 225, V MAX SHO 200, the new V MAX SHO 175 and the V MAX SHO 150.

Like other members of the V MAX SHO family, the V MAX SHO 115 is light, weighing in at just 377 pounds, and it has the added benefit of not needing two-stroke oil or an oil tank (or the added weight). A competitor's two-stroke weighs 390 pounds. In fact, the    V MAX SHO 115 is the lightest four-stroke DOHC 115-horsepower outboard on the water. It uses a lightweight composite lower pan and cowling, a single-ram power trim and tilt mechanism and a lightweight mounting bracket. 

The 1.8-liter V MAX SHO 115 features Yamaha's advanced 16-valve double-overhead cam (DOHC), four-cylinder design, which means better breathing for better performance. (Another competitor's 115 has only eight valves.) 

Its large intake and exhaust valves generate more power and midrange torque. They are fed by a large (60mm) single throttle body with Yamaha’s long-track intake system and a free-flow exhaust. 

Full-throttle rpm range is 6,300, which means Yamaha can better tailor the gear ratio for low speed thrust and still deliver great top end speed. A knock sensor, an unexpected feature in this class of outboard, allows the engine to operate constantly at peak output. The result is great top speed, 2.7 miles per hour faster than that of the next generation Yamaha F115 recently introduced. 

The V MAX SHO 115 powerhead is based on proven, advanced Yamaha four-stroke technology. It also uses Yamaha’s Phaze Five™ paint system, which includes the electro-deposition of anti-corrosive paint on both the inside and outside passages of the engine block. 

Inside the engine, dimpled cylinder sleeves, like those used on the Yamaha F350 V8, reduce weight and add strength. They also aid in heat transfer and help to keep the engine reliably cooler. 

Because it is a four stroke, the new outboard is quiet by nature. In addition, Yamaha has harmonized all the inertial mass components and added large rubber engine mounts. The result is smooth and quiet operation, unparalleled in its class. 

The new V MAX SHO 115  is expected to be available in early spring 2015.
