  • Shallow water drive
  • High output charging
  • Large displacement for more power
  • Available Power Thrust for increased performance
Performance and Efficiency
  • 4-Stroke Design: World-renowned Honda quality combines proven reliability and superior fuel efficiency, with no oil mixing.
  • Available with Power Thrust Design (BFP) - better performance: 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 - increased manueverability (BFP models): The exhaust relief feature creates more power in reverse by minimizing cavitation around the propeller blades. The exhaust relief is located above the cavitation plate, allowing the prop to run in clean, exhaust-free water.
  • Large Displacement: At 21.4 cubic inches, the 15hp has one of the largest displacements in its class. Along with the long-stroke design, this provides optimum torque throughout the RPM range.
  • Easy One Hand Starting: A built-in decompression release and digital CDI system set the BF15’s ignition timing. This reduces the effort required to pull-start the engine by hand by 40%!
  • Auto Start Enrichment - easy starts: Auto Start Enrichment acts as an automatic choke. Just like a fuel injection system, it automatically adjusts the air/fuel mixture for quick, easy starting and warm-up.
  • Pendulum Mount System: Honda's exclusive triangulated rubber mount system absorbs vibration and provides unbelievably smooth operation.
  • 3 Stage Carburetion: Conventional 2-circuit carburetors go directly from a lean mixture at idle to a rich setting at full throttle. The BF15 adds a third stage for better economy and smoother operation.
  • EZ Steer Friction Control: A unique lever design allows you to precisely adjust steering tension for improved control and comfort.
  • Shallow Water Drive: An innovative shallow water drive feature lets you tilt the motor up, allowing you to easily operate in shallow areas. Shallow water drive greatly reduces the risk of engine damage.
Reliability and Durability
  • Engine Alert System - Keeps you informed: The integrated warning system protects the engine from severe damage due to low oil, over-revving and overheating.
  • 4-Front Corrosion Protection System - Fights the elements: A patented, "Double Sealed" multi-layered paint process. Sacrificial anodes and stainless steel technology, along with waterproof connectors, all enhance corrosion protection.
  • 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 conscious technology. All Honda Marine engines exceed the highest CARB 3-Star rating to meet the rigorous California Air Resource Board's standards.
  • True 5 Warranty: Honda's True 5 Warranty is the best in the business. This transferable, non-declining warranty is the same on the first day as it is on the last.
Convenience and Ease of Use
  • Lightweight Design: The lightest 4-stroke model in its class, the BF15 is easy to transport and convenient to mount.
  • Power Tilt: Conveniently allows user to tilt the unit out of the water. At low speeds acts like a power shallow-water-drive device, permitting access to the shallow water areas.
  • High Output Charging: The BF15 has the largest alternator in its class. It generates 12 Amps at only 3000 RPM. This helps to maintain battery charge and keep electronics running at trolling speeds.
  • Integrated Carring Handle: A integrated carrying handle makes transporting the engine a breeze. The convenient, foldaway carry handle is situated at the exact top/bottom balance point of the engine. This means the engine carries more easily in a level position.
  • Longer Tiller Handle: A convenient longer tiller handle improves control and reduced steering effort. The extended handle is made of a lightweight composite, increasing its durability while decreasing the motor's weight.
  • Up Front Tiller Controls: A convenient front-mounted shift lever allows fingertip shifting. The Twist Grip Throttle & Tensioner minimize driver fatigue.
