F25

Small engine. Serious power. Serious features.

Open up the throttle on the F25 and you’ll understand why it’s in a class of its own. This is a versatile twin-cylinder 4-stroke with big performance, a smooth ride, and brilliant fuel economy. It also handles easily and is kinder to the environment, with reduced exhaust emissions.

And, you also enjoy benefits normally only found on larger engines, such as computer-controlled ignition, a special light-load starting system, and a large-volume silencer. Additional features include precise single-lever steering friction adjustment, a high-output alternator and Wide Range Power Trim & Tilt system.

It all adds up to a great choice for commercial, professional or leisure use.
