The Honda BF8 and BF9.9 deliver more of what boaters want: stronger battery charging, easier-to-use features, quieter operation, and dependable performance in a lightweight, portable package. A reliable PGM ignition system keeps timing precise across the full RPM range, while easy one-hand starting and Auto Start Enrichment (an automatic choke) make startup nearly effortless. Shallow water drive and available power tilt let you access shallow areas with minimal risk of engine damage, and the rounded, lightweight design with an integrated carry handle makes transport simple. Front-mounted tiller controls, a longer composite handle, and EZ Steer friction control add up to more comfortable operation on the water.

An integrated engine alert system guards against low oil, overheating, and over-revving, and a multi-layered corrosion protection system keeps the engine looking and running like new. Best-in-class charging output — 2 amps at 1000 RPM up to 12 amps at 3000 RPM — keeps your battery and electronics powered even at trolling speeds, while Honda’s pendulum mount system smooths out vibration for a comfortable ride.
