Features

Weighing in at a mere 101 pounds, Honda Marine’s BF15 and BF20 are the first four-stroke outboards of their kind to weigh less than most comparable 9.9hp engines on the market.

The BF15’s light weight, combined with PowerThrust, an Integrated Carrying Handle and exceptional quietness at cruise, make it the perfect choice for pontoons and inflatable yacht tenders, or as a “kicker” on a larger fishing boat.

The BF15 from Honda Marine…make a quiet entrance.

4-Stroke Design World-renowned Honda quality combines proven reliability and superior fuel efficiency, with no oil mixing.

Power Thrust Design (BFP) The 10" x 7 5/8" Power Thrust 4-blade propeller creates 60% more thrust in reverse and 15% more in forward. The result-improved maneuverability and performance.

Reverse Exhause Relief Additional exhaust relief above the cavitation plate produces more thrust by allowing the prop to run in clean, exhaust-free water.

Large Displacement At 21.4 cubic inches the 15hp has the largest displacement in its class! Along with the long-stroke design, this provides optimum torque throughout the RPM range.

Lightweight Design The lightest 4-stroke model in its class, the BF15 is easy to transport and convenient to mount.

Easy One Hand Starting A built-in decompression release and digital CDI system set the BF15’s ignition timing , greatly reducing the effort required to pull-start the engine by hand!

PGM Ignition A reliable microprocessor accurately controls ignition timing during start-up and across the entire RPM range, providing optimum overall operation.

High Output Charging Generating 12 Amps at only 3000 RPM to maintain battery charge and keep electronics running at trolling speeds, the BF15 has the largest alternator in its class.

Auto Start Enrichment (ASE) Standard on electric start models, Auto Start Enrichment automatically adjusts the air/fuel mixture for quick and easy starts and warm-ups.

Pendulum Mount System Honda's exclusive triangulated rubber mount system absorbs vibration and provides unbelievably smooth operation.

Integrated Carring Handle Situated at the exact top/bottom balance point of the engine, the BF15’s integrated carrying handle make transporting it a breeze.

3 Stage Carburetion While conventional 2-circuit carburetors go directly from a lean mixture at idle to a rich setting at full throttle, the BF15/20 adds a third stage for better economy and smoother operation.

Engine Alert System The integrated warning system protects the engine from severe damage due to low oil, over-revving and overheating.

Corrosion Protection System A patented, "Double Sealed" multi-layered paint process. Sacrificial anodes and stainless steel technology, along with waterproof connectors, all enhance corrosion protection.

Fresh Water Flushport Flushes debris and saltwater out of the engine, extending the life of the outboard.

Longer Tiller Handle Made of a new lightweight composite, the BF15’s longer tiller handle improves control while reducing steering effort.

Up Front Tiller Controls A convenient front-mounted shift lever allows fingertip shifting while a Twist Grip Throttle & Tensioner minimize driver fatigue.

EZ Steer Friction Control Unique lever design allows operator to precisely adjust steering tension for improved control and comfort.

Shallow Water Drive Allows you to run in shallow water and greatly reduces the risk of engine damage.

Positive Lubrication A crankshaft-driven, automotive-style trochoid oil pump ensures long-term durability of critical engine components.

Ultra Low 3 Star Carb Emissions Environmentally friendly technology.
