Features

Convenience & Control

  • 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.
  • PORTABILITY AND STORAGE: Incredible light weights, built-in resting pads and carry handles, an easy oil retention system and an optional folding tiller handle, allow for easy carrying and on-side storage without oil leakage or cowling scuffs.

Features

  • Prop Shaft Horsepower - 25 hp at 5,500 rpm
  • Compression Ratio - 9.3:1
  • Recommended Fuel - Octane 87
  • Recommended Fuel Filtration - Yamaha 10-micron fuel / Water separating filter (external)
  • C.A.R.B. Rating - 2-Star
  • Intake - 4
  • Spark Plug - DPR6EB-9
  • Ethanol Blend Limit - 10% maximum
  • Compatible with Remote Mechanical Control
  • Compatible with Command Link®, Y-Cop®

Power & Performance

  • EFFICIENT POWER: The F25 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

Reliability & Durability

  • 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.
  • 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.
  • 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.
