The four-valve, two-cylinder, Single Overhead Camshaft delivers sufficient torque from low to mid speed ranges for a quick response and smooth running.
Battery-Less Fuel Injection
The F25 is the first battery-less fuel injection system in Yamaha’s four-stroke range, making engine set-up more simple and convenient for pull-start models. The system takes into account engine requirements to achieve maximum engine performance including ‘first-time, every-time’ hot and cold starting.performance including ‘first-time, every-time’ hot and cold starting.
Digital Gauges Compatible
The F25 is fully compatible with Yamaha's Digital Network Gauges (Command Link), giving you the information needed to maximise engine performance and efficiency. This engine is also NMEA2000 compatible allowing the F20 to share information with third party multi-function displays, GPS and fish finders.
Fresh Water Flushing System
Simply connect a hose to the easy access connector to flush salt and dirt from the outboard without having to run the engine. Flushing the engine after each usage reduces corrosion and extends the engines life.
A 16 Amp high-output alternator ensures that power is always available to start the engine, even after long periods of idling or running at low revs. This not only provides extra starting power, but delivers sufficient power to run the wide array of on-board electronic devices used in modern boating. (Battery charging kit optional)
Optional Multi-Function Tiller
With the latest technologies, ergonomic design and features, Yamaha's Multi-Function Tiller Handle delivers effortless control, maneuverability and comfort. Trim, shift, throttle, stop switch, variable trolling and integrated overheating and low oil pressure warning alerts are also built into the handle.
Yamaha’s push-button control makes engine tilt adjustments quick, smooth and easy, across a wide range (Power Tilt model only).
Variable Trolling Control
Yamaha’s variable trolling control allows you to precisely adjust the engine’s idling speed from 750 to 1050 RPM, in 50 RPM increments. The ability to finely tune the trolling speed allows fisherman to perfect their lure presentation when chasing different species of fish.
Wide Span Mounting System
The large rubber mounts and the wide length between the mounts help to reduce engine vibration.
Mechanical Steering Control
The F20 has the choice between tiller or forwards mechanical control options.
Anti-Corrosion Paint System
Yamaha engines are known for their durability and high re-sale value. Part of this lies in the anti-corrosion protection. A unique YDC-30 aluminium alloy and 5-stage exterior paint coating process protects the engine's exterior parts, while high-quality, marine-grade stainless steel componentry is used through-out.
