Yamaha F115
Technical details
Producer: YAMAHA (JP)

Yamaha Marine Group introduced 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. 

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 FiveTM 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.
