About this engine

For mid and smaller horsepower needs, there’s plenty of punch in the Honda BF30 and BF25. But it’s power you’ll feel and never hear. That’s because all Hondas are whisper quiet. So extraordinarily quiet, we don’t have to put extra dampening insulation in the cowling like most manufacturers do. Instead we pack ‘em full of features. Like a Center Mount Tiller with up-front controls. The 3 to 3 Induction system that provides smooth, quiet operation. And Autostart Enrichment, which makes starting a breeze. And of course, the exceptionally durable BF25 and BF30 are backed by the best standard warranty you can get. The end result? More good times on the water.

Key features

  • Increased Displacement For More Power: The BF25 and 30 are among the largest displacement in their class, at 552 cc (33.7 cubic inches).
  • 3 to 3 Induction: 3 to 3 induction provides smooth, quiet operation, along with instant throttle response and performance.
  • PGM Ignition: A reliable microprocessor accurately controls ignition timing during start-up and across the entire RPM range, providing optimum overall performance.
  • Forced Air Ventilation: The unique air intake on the top of the cowl allows cooler air to enter and warmer air to escape.
  • 3 Inlet Cooling: Provides plenty of water to maintain optimum engine temperature in all conditions.
  • Honda Quality: Our outboards share many technologies and components used in Honda vehicles, with all the benefits of years of proven Honda engineering, precision manufacturing and reliability.
  • Unmatched peace of mind: Honda's True 5 Warranty is the best in the business.
  • Engine Alert System: The Engine Alert System uses visual, audio and RPM reduction circuits to alert the operator of over-heating, low oil PSI and over-revving.
  • Honda Corrosion Protection: Your Honda can continue to look and perform like new, thanks to our corrosion protection system.
  • Easy Starting: Auto Start Enrichment acts as an automatic choke.
  • High Output Charging System for more power: A rectifier/regulator is standard on both manual and electric-start models.
  • Easy Maintenance: Easy access side-mounted oil filter and oil fillers simplify maintenance, while "screw-type" valve adjusters reduce maintenance costs.
  • Convenient Controls: The center mounted, ergonomically designed tiller handle is longer for improved handling.
  • Forward Mounted Shift Lever: Provides easy access to the forward-mounted controls.
  • Gas Assist Tilt: Acting much like a pressure strut on a car's trunk lid, the gas-filled cylinder makes it easy to tilt the engine for running in shallow water, or to raise it completely out of the water for protection.
  • Power Trim/Tilt: Allows you to trim the unit for maximum performance and handling.Trim Range: - 4° to +12°Tilt Range: 64°
