Honda BF 20

20 HP14.7 kW350 cm³OHC – 2 cylinders

The lightest 20 HP four-stroke outboard in its class, engineered to remain surprisingly portable despite its impressive output. Proven PGM-IG electronic fuel management – borrowed from higher-horsepower models – delivers the optimal air-fuel mixture at any speed, making it significantly more economical than conventional carburetted designs. The 350 cc twin-cylinder powerhead boasts the largest displacement in its class, producing outstanding torque across the full RPM range. A pendulum-mounted engine cowl provides virtually vibration-free cruising. Multiple electronic safeguards – oil-pressure monitoring, overheat detection and over-rev protection – keep the engine safe under all conditions. Available with tiller or remote steering, recoil or electric start, short or long shaft, and even an optional power-tilt version. The optional Power Thrust propeller kit delivers 60% more thrust in reverse and 15% more forward – ideal for heavier hulls and demanding manoeuvring.
