Model Description


Small-engine convenience. Big-engine performance.


If you’re looking for the winning combination of easy handling, smooth power and great control, then look no further than the F15, F20 or F25.


These versatile twin-cylinder, 4-stroke engines offer the optimum power-to-weight ratio, along with standout fuel economy. Which means they’re kinder to your pocket – and to the environment – cutting exhaust emissions to a minimum.

For professional or leisure use, these compact engines are ready to deliver.
