Power and Performance
PrimeStart™ Auto-Enrichment System: Provides easy, turn key starting, smooth acceleration, and maximum fuel economy.
Composite Intake Manifold: The long tube intake tracks are tuned to increase 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 air noise while the surge tank reduces air turbulence for smoother operation.
Microcomputer Ignition: Adjusts timing to maintain optimum engine performance, economy and power under all conditions.
Single Overhead Cam: Provides a compact, lightweight, space-saving design that won the "Motor Boat and Sailing" award for innovation!
Reliability and Durability
Top-Mounted Flywheel: Helps protect sensitive electrical components from harmful corrosion.
Three-Year Limited Warranty: Our Three Year Limited Warranty protects every Four Stroke for pleasure use.
Freshwater Flush Device: Allows you to flush the engine without running it, for added convenience and long-engine life.
YDC-30 Alloy: Yamaha's Exclusive YDC-30 Alloy is the most corrosion-resistant base material in the industry. Used with Yamaha's Exclusive ACP-221 Paint Process, it provides an extra-tough barrier against corrosion. They're both key components of our renowned Ultimate Corrosion Protection System that's standard on all Yamaha Midrange Four Stroke engines.
Convenience and Control
Single Throttle Valve: Simple, lightweight design allowing for quick and easy adjustment. The air silencer box reduces intake air noise to a minimum with the use of a highly porous nylon cloth that soaks up the noise making these engines whisper quiet while the surge tank reduces air turbulence for smoother operation.
Multi-Function Tiller Handle: The New, Multi-Function Tiller Handle puts easy control at your fingertips in a sleek, ergonomic new design.
High Output Alternator: Keeps your batteries charging even when you're running multiple electronics.
Federal EPA Emission Requirements: All Yamaha four strokes meet all Federal EPA emission requirements. Our entire four stroke line-up (except the F2.5) has earned a California C.A.R.B. three-star rating for ultra-low emissions. Our F2.5 model has earned a two-star rating for very low emissions.
