YAMAHA F25 PORTABLE MECHANICAL ES

Convenience & Control

– 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.
– 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.

Power & Performance

– 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.

Reliability & Durability

– 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.
