2021 Yamaha Marine F115 Jet Drive

The F115 has been redesigned, receiving a state-of -the-art air intake and fuel injection system. With added technology and its proven DOHC four-cylinder 16-valve 1741cc engine the efficient F115 makes for the best choice to power your boat for years to come.

Features may include:

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

• 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.

• 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.

• 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.

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

• 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.

• 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.

• 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.

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

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