Yamaha introduces new F175A and F115B four-stroke engines.

The Yamaha F175A fills a gap in the in the current range of in-line four-cylinder outboards.

Yamaha has announced two new models in Australia: the new F175A and F115B. According to Yamaha, the new F175 fills a gap in the current range of inline four-cylinder outboards, while the F115B will replace the Yamaha F115A

 

YAMAHA F175

Yamaha says the F175 is based on the award-winning 2.8lt F200 platform, sharing the same displacement and four-cylinder, 16-valve double-overhead-camshaft design. It uses a single-throttle intake valve that is said to reduces weight while increasing efficiency, and a knock sensor allows the engine to run at peak efficiency and performance at a high rev rate regardless of conditions.

The engine has a 50amp electrical output to keep up with today’s electronic accessories. It is also compatible with the Yamaha Command Link gauges and hardware, as well as the Y-COP theft deterrent system. The outboard also includes Yamaha’s Variable Trolling function when fitted with Yamaha’s Command Link gauges.

The F175 is compatible with Yamaha’s Shift Dampening System (SDS) range of propellers. This system utilises a splined rubber hub designed to absorb the force created when an outboard is shifted into gear. The F175 is mechanically controlled for ease of use in both new boat and repower applications.

 

 YAMAHA F115B

Yamaha says the new F115B, at 171kg, is 15kg lighter than the previous generation F115A; Yamaha also says it is 11kg lighter than the nearest four-stroke competitor. Weight savings are derived from a variety of new materials, such as a composite cowling, a single-ram power trim and tilt mechanism, and a new lightweight mounting bracket.

The F115B has increased cubic capacity, which now measures 1.8 litres. The outboard’s Double-Overhead Cam (DOHC) four-cylinder design now has larger intake and exhaust valves for easier breathing, more power and better mid-range torque. The compression ratio has been increased, and so has the full-throttle RPM range – now up to 6,300rpm. A knock sensor allows the engine to operate reliably at peak output. Yamaha says the result is great response throughout the RPM range and terrific acceleration.

The new Yamaha F115 is mechanically controlled and compatible with Yamaha’s Command Link gauges and hardware as well as the Y-COP theft deterrent system. The outboard also includes Yamaha’s Variable Trolling function when fitted with Yamaha’s Command Link gauges or Multi-function Tiller Handle.

Yamaha added that the new F175A outboard will be available from April 2014; the new Yamaha F115B outboard will be available from the beginning of May.
