Super High Output Four-Stroke Series Expands to Include Smaller Boats
Fall, 2014 — Yamaha Motor Canada introduced today a V MAX SHO for smaller craft, the V MAX SHO 115, an outboard that will bring all the attributes of the four-stroke series to a much larger group of boaters and anglers.
“The light and compact V MAX SHO 115 offers smaller boat owners the performance usually associated with two strokes, with all the advantages of a four stroke –convenience, fuel efficiency and quiet operation,” says Yamaha Motor Canada’s National Manager Marine, Jean Francois Rioux.
Along with the new V MAX SHO 175, the V MAX SHO 115 arrives on the heels of the successful V MAX SHO 250, V MAX SHO 225, V MAX SHO 200 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 engine 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-litre 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 mid-range 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 MAXSHO 115is expected to be available in Spring 2015.
