Zaloudek's Marine Honda Engines - Portables 20HP  - A portable powerhouse

Zaloudek's Marine - Honda Marine Logo

Performance and Efficiency

  • 4-Stroke Design
  • Available with 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 Exhaust Relief (BFP models)
  • Large Displacement - At 21.4 cubic inches, the 20hp 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 BF20’s ignition timing. This reduces the effort required to pull-start the engine by hand by 40%!
  • Power Tilt - Conveniently allows user to tilt the unit out of the water. At low speeds, Power Tilt acts like a power shallow-water-drive device, permitting access to the shallow water areas.
  • Auto Start Enrichment (ASE)
  • Pendulum Mount System
  • EZ Steer Friction Control - A unique lever design allows you to precisely adjust steering tension for improved control and comfort.
  • 3 Stage Carburetion - Conventional 2-circuit carburetors go directly from a lean mixture at idle to a rich setting at full throttle. The BF20 adds a third stage for better economy and smoother operation.
  • PGM Ignition - A reliable microprocessor accurately controls ignition timing during start-up and across the entire RPM range, providing optimum overall operation.
  • 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


Convenience and Ease of Use

  • Lightweight Design - The lightest 4-stroke model in its class, the BF20 is easy to transport and convenient to mount.
  • High Output Charging - The BF20 provides 2 Amps at 1000 RPM and an amazing 12 amps at only 3000 RPM. This helps to maintain the battery charge or keep electronics going - even at trolling speeds.
  • Integrated Carrying 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.
  • Available in both 15-, and 20-inch shaft models
