Honda BF2.3 - Features and Technical Specifications

Weighing only 29.5 pounds, the Honda Marine BF2.3 is the lightest four-stroke outboard motor in America.  The single-cylinder, 57.2 cc engine incorporates a number of innovative features, including Shallow Water Drive, Twist Grip Throttle, Front-Mount Carrying Handle, and 4-Front Corrosion Protection. Within this striking new package is an engine that optimizes performance, has best-in-class fuel economy, and offers reduced emissions (as compared to the Honda BF2 model it replaces).

The Centrifugal Clutch on the Honda BF2.3 maintains a smooth idle for easy trolling, automatically engaging the propeller when the throttle is advanced.  The engine also incorporates a Full Swivel Bracket designed to enhance overall durability by reducing vibration to the tiller handle.  And since the outboard does not require a water pump, clogging and drainage from weeds or sand are never a concern.
