2023 Yamaha 20HP For Sale – 20″ Shaft

• Efficient Power: The F25, F20 and F15 all feature a two-valve-per-cylinder, single-overhead-camshaft design that provides better breathing and more power.
• Optimum Performance: An optimally balanced crankshaft and labyrinth exhaust deliver smooth power, while Microcomputer Ignition adjusts timing to maintain maximum engine performance, economy and power under all conditions
• Streamlined Intake: An intake silencer and manifold on the F20 and F15 result in more direct airflow, for minimum noise and maximum power.
• Responsive Acceleration: An acceleration pump on the F20 and F15 gives the engine the fuel it needs–when it needs it–like during rapid throttle advance. This ensures responsive acceleration.

• Optimal Operation: CDI Microcomputer Ignition monitors throttle position, engine speed and atmospheric conditions in order to precisely adjust ignition timing under all conditions for optimum ignition performance, ensuring smooth and reliable operation.
• Wet Sump: A pressurized oil delivery system incorporates a compact and durable oil pump to keep all of the moving parts of their SOHC systems lubricated and running smoothly for maximum reliability.
• Engine Warning System: Protects the outboard with a range of functions including: overheat protection and low-oil-pressure warning (automatically reducing maximum RPM to 2000), over-rev protection, start-in-gear protection and shift-in prevention at open throttle.
• Corrosion Protection: Combined with our proprietary alloy (YDC-30), our exclusive Phaze Five™ electro-deposited, anti-corrosive paint system provides a tough, five-layer barrier against corrosion. This protection is standard on all Yamaha Portable four-stroke outboards.

• Max Maneuverability: A 45-degree steering angle in each direction means great maneuvering potential.
• Easy Engine Flushing: A Freshwater Flush Device allows you to flush the engine without running it, for added convenience and extended engine life.
