Yamaha F25 Portable Mechanical ES F25SWC Outboard Motor 2018

Description

Our 432-cc 25-hp portable outboard boasts a class-leading power-to-weight ratio and a sleek, lightweight design. Actually, it’s the lightest 25-hp outboard—two- or four-stroke—on the water. Despite being 25% lighter due to its streamlined design, it still has interesting features like battery-less EFI. This capability is now available for pull-start models, and the system is built with an automatic decompression device to make manual starting even less labor-intensive.

Convenience and Control

CORROSION PROTECTION: Our unique Phaze FiveTM electro-deposited, anti-corrosive paint technique, when combined with our proprietary alloy (YDC-30), offers a robust, five-layer corrosion barrier. All Yamaha portable four-stroke outboards come equipped with this protection as standard.
MAX MANEUVERABILITY: Excellent maneuverability is possible with a steering angle of 45 degrees in each direction.

EASY ENGINE FLUSHING: For increased convenience and longer engine life, a freshwater flush device enables you to flush the engine without starting it.
PORTABILITY AND STORAGE: simple carrying and on-side storage without oil leaks or cowling scuffs are made possible by incredibly light weights, integrated resting pads and carry handles, a simple oil retention system, and an optional folding tiller handle.

Power and Performance

EFFICIENT POWER: The single overhead camshaft, two-valve-per-cylinder architecture of the F25, F20, and F15 offers increased power and improved ventilation.
OPTIMUM PERFORMANCE: Microcomputer Ignition modifies timing to preserve maximum engine performance, economy, and power under all circumstances, while a crankshaft and labyrinth exhaust provide smooth power.

STREAMLINED INTAKE: The F20 and F15 have a manifold and intake silencer that guide airflow for optimum power and little noise.
RESPONSIVE ACCELERATION: The F20 and F15 have an acceleration pump that provides the engine with the fuel it requires at the right time, such as during rapid throttle advance. This guarantees responsive acceleration.

Reliability and Durability

IDEAL OPERATION: CDI Microcomputer Ignition keeps track of engine speed, throttle position, and atmospheric conditions to accurately adjust ignition timing in any situation for optimal ignition performance, guaranteeing dependable and seamless operation.
WET SUMP: To provide optimal dependability, a pressured oil supply system includes a small, robust oil pump to keep all of the moving components of their SOHC systems lubricated and operating smoothly.

The engine warning system provides a number of safeguards for the outboard, such as shift-in prevention at open throttle, over-rev protection, start-in-gear protection, and low-oil-pressure alert, which immediately lowers the maximum RPM to 2000.
