The F115 delivers on Yamaha's desire to make each new generation of outboards lighter and more efficient.The redesigned F115 started with the venerable DOHC in-line, four-cylinder 16-valve engine that set the standard for reliability and durability, then added new technologies to make a highly efficient package.

COMPACT, LIGHTWEIGHT

In-line 4-cylinder design is quiet, clean-burning and fuel efficient with Yamaha's famous durability.


16-VALVE DOUBLE OVERHEAD CAM

By using four valves per cylinder with 1 cam for the intake valves and 1 cam for the exhaust valves this DOHC design efficiently exchange intake and exhaust gases for responsive power and fuel efficiency.


DIRECT DRIVE

Valves are activated through direct contact with the camshaft, for more precise valve timing control. Therefore rocker arms and their adjustment are eliminated for increased reliability and less maintenance.


MULTI-POINT ELECTRONIC FUEL INJECTION

Independent fuel injectors are electronically controlled to deliver the precise amount of fuel for each individual cylinder for superior engine performance and maximum fuel economy.


SINGLE THROTTLE VALVE

Simple, lightweight design for
greater precision, reliability and ease of serviceability.


COMPOSITE INTAKE MANIFOLD

The long tube intake tracks are tuned to maximize air flow increasing low end and midrange torque performance resulting in a more powerful hole shot and increased acceleration. The air silencer box reduces intake noise while the surge tank reduces air turbulence for smoother operation.


MICROCOMPUTER IGNITION

Adjust timing to maintain optimum engine performance, economy and power under all conditions. Along with reliable electronics, including a knock sensor letting the engine self detect combustion problems and adjust itself accordingly before damage could occur.


ACP-221 PAINT PROCESS AND YDC-30 ALLOY

Yamaha's exclusive YDC-30 alloy is the most corrosion-resistant base material in the industry. Used with Yamaha's exclusive paint process, it provides an extra-tough barrier against corrosion. They are both key components of our renowned Ultimate Corrosion Protection System.


FRESHWATER FLUSH DEVICE

Allows you to flush the engine without running the engine using a standard household garden hose, for added convenience and long engine life.


THREE YEAR LIMITED WARRANTY

Every Yamaha Four Stroke is protected by our 3-Year Limited Warranty for pleasure use.


OPTIONAL COMMAND LINK

Yamaha instrumentation puts all vital system information right at your fingertips. You know they're accurate, because they're designed for your Yamaha outboard. They're easy to read, and engineered to withstand the elements. Command Link® Digital Gauges gives you access to more information, using fewer gauges, and they allow you to configure the information any way you want.


OPTIONAL MULTI-FUNCTION TILLER HANDLE

All control features are located on the tiller handle for convenience. The throttle, throttle friction control, shift lever, key switch, stop switch, power trim and tilt switch. Additionally, the tiller handle is extra long and centre-mounted for
added convenience.


OPTIONAL TILT-UP STOPPING DEVICE

Allows to adjust the fully tilt-up setting and meet the specific requirements to avoid contact between the engine and the boat.
