Honda BF20 Outboard Motor 2024 – 20HP Four Stroke

Honda BF20 2024: Top Output from Honda’s 350cc Twin

The 2024 Honda BF20 is the strongest tune of Honda’s 350cc long-stroke OHC twin — a full 20HP (WOT 5,000–6,000 rpm) at just 104 lbs, lighter than some 9.9s on the market. The big displacement produces optimum torque across the entire rpm range, microprocessor-controlled ignition times every spark precisely, auto start enrichment kills the choke ritual, and the class’s highest-output charging system powers electronics even at trolling speed. Available in manual, electric, tiller, remote, power tilt, and Power Thrust (BFP) configurations — the premium heavyweight of the 20HP outboard class.
