  • Reliability in a Compact Design

    With a high output 350cc displacement and long-stroke design, the BF15 and BF20 are top performers, providing optimum torque at any speed. Programmed Ignition (PGM-IG) also accurately controls ignition timing during start-up and across the entire rev range for optimum overall operation.

    A 12amp (electric start) alternator also ensures excellent charging power to keep batteries in top condition. Thanks to their incredible lightweight, the engines are also very easy to transport. A foldaway handle positioned at the exact balance point of each engine makes it easy to carry the outboard in a level position.

    Superior Handling Power

    The BF20 is equipped with Power Tilt and Gas Assist Tilt variations – perfect for effortless engine tilt operations and shallow-water running. Cruising is improved and more comfortable with Honda’s unique pendulum-motion mounting system. This system, featured in both the BF15 and BF20, is specially designed to reduce vibration and maximise user comfort.

    A convenient Forward Mount Shift Lever allows fingertip shifting, while a Twist Grip Throttle and Tensioner ensures superior throttle friction, minimising driver fatigue.

  • Power Tilt & Gas Assist Tilt

    Honda’s exclusive Power Tilt, Gas Assist Tilt and Manual Tilt variations put these engines in a class of their own.

    Reverse Exhaust Relief

    Exhaust gases are diverted away from the
    propeller while in reverse, allowing the propeller to run in clean water.

    Highest Amps

    12amp (electric start) and 6amp (manual start) alternators keep batteries in top condition with a lot more charging power.

    Broad Range of Models

    The BF20 is available in nine separate model variations including manual or electric start, power or gas assisted tilt, and tiller or forward control.

    High output 350cc displacement engine. Provides superior torque throughout the entire rev range. Auto Start Enrichment (on electric start models) automatically adjusts the air/fuel mixture for quick, easy starting and warm-up just like fuel injection.

    12amp (electric start) alternator ensures battery charge is maintained while operating electronics and other accessories. Convenient foldaway handle positioned at the exact balance point of each engine makes it easy to carry the outboard in a level position.

    4-Front Corrosion Protection. A patented, ‘double-sealed’ multi-layered paint process. Sacrificial anodes and stainless steel technology, along with waterproof connectors, all enhance corrosion protection.
