The exciting new F25 delivers the weight and performance you would expect from a two-stroke, with all of the advantages that comes with Yamaha’s industry-leading four-stroke technologies. This new generation outboard is not only an improvement on the four-stroke model it replaces, but also exceeds the all-round capabilities of Yamaha’s legendary 25N two-stroke outboard. For the first-time in Yamaha’s four-stroke history, the new F25 comes with battery-less fuel injection – delivering easier starts, better fuel economy and an improved overall operating performance.Through smart design, the new compact F25 is now the lightest 25 horsepower outboard in its class - 20Kg lighter than its four-stroke predecessor and less than 10 kg heavier than Yamaha’s 25N two-stroke. This engine comes packed with additional features including Yamaha’s variable trolling and YCOP remote security, and is compatible with Yamaha’s range of command link gauges.

Built-in See Through Fuel Tank

For increased range and convenience this engine includes a switch-over facility which allows for the quick connection of an additional external fuel tank, should it be required.
Two-Way Throttle Control
Throttle is controlled by a two-way cable rather than relying on a traditional throttle return spring. This ensures long term durability, added safety and an enhanced feeling of immediate control.
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 systems. A unique YDC-30 aluminium alloy and 5-stage exterior paint protects the engine's exterior parts, while high-quality, marine-grade, stainless steel componentry is used throughout.
