Yamaha’s New F115 lightest in 115 four-stroke class

KENNESAW, Ga.–(BUSINESS WIRE)– Yamaha Marine Group introduced today its newly redesigned F115 outboard, which is not only more powerful and compact, but also now the lightest outboard in the 115 horsepower four-stroke class.

“With a host of enhanced features and benefits, our redesigned F115 is a true category leader,” said Ben Speciale, Yamaha Marine Group President. “The outboard’s incredible versatility makes it the perfect choice for applications ranging from pontoons to flats boats.”

At 377 pounds, the new F115B is 24 pounds lighter than the previous generation (F115LA). Weight savings are derived from a variety of new materials, such as a composite lower pan and cowling, a single ram power trim and tilt mechanism, and a new lightweight mounting bracket. The F115’s all-new powerhead provides increased bore and stroke, which now measures a full 1.8 liters. The outboard’s double-overhead cam (DOHC) four-cylinder design now has larger intake and exhaust valves for easier breathing, more power and better midrange torque.

Complementing the new valves and cylinder head is a new 60mm single-throttle body with Yamaha’s long-intake track system and a new free-flow exhaust manifold. Compression ratio is increased, and so is the full-throttle rpm range: 5,300 to 6,300 rpm.

A knock sensor allows the engine to operate constantly at peak output. One result is terrific acceleration and a zero-to-200-foot time that’s 0.7 seconds faster than its predecessor*.

The new F115 model is mechanically controlled and compatible with Yamaha’s Command Link^® gauges and hardware as well as Y-COP^® theft deterrent system. To help mitigate corrosion, the F115 uses Yamaha’s Phaze Five^TM paint system, which involves the electro-deposition of anti-corrosive paint on both the outside and inside passages of the engine block. The outboard also includes Yamaha’s Variable Trolling RPM Switch (VTS^®) and can be equipped with Yamaha’s award-winning Multifunction Tiller Handle.

The new F115 outboard is expected to begin shipping in the second quarter of 2014.
