Honda BF 25
Honda’s 25 horsepower engine has a powerful three-cylinder design for maximum torque. The convenient Auto-Start Enrichment automatically adjusts the air-fuel mixture for quick, easy starts and warm up. Like the 30 / 40 / 50 HP, the 25 features a new center mount tiller handle for ease of operation and control. And it’s available with an all new power trim and tilt system.
