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.
World-renowned Honda quality combines proven reliability and superior fuel efficiency, with no oil mixing.
The BF25 and 30 have the largest displacement in their class, at 552 cc (33.7 cubic inches). This provides more torque in midrange operation.
The ergonomically designed tiller handle is longer for improved handling. Adjustments for throttle and steering friction allow easier control. Up front shift lever, PTT switch, and engine alert lamps provide added convenience.
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.Learn More
3 to 3 induction provides smooth, quiet operation, along with instant throttle response and performance. A compact 3-cylinder, 3-carburetor design utilizes one carburetor per cylinder. This design is more responsive than competitive throttle bodies with long intake runners.
A reliable microprocessor accurately controls ignition timing during start-up and across the entire RPM range, providing optimum overall operation.
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.
A patented, "Double Sealed" multi-layered paint process. Sacrificial anodes and stainless steel technology, along with waterproof connectors, all enhance corrosion protection.Learn More
The port-mounted oil filter and oil fillers simplify maintenance. Easy "screw-type" valve adjusters require no shims, reducing maintenance costs.
Patented non-linear rubber mounts provide smoother operation at all engine speeds.
Provides plenty of water to maintain optimum engine temperature in all conditions.
Audio and visual cues combine with RPM reduction circuits to alert the operator of overheating, low oil PSI and over-revving to prevent engine damage.
Unique air intake on the top of the cowl allows cooler air to enter and warmer air to escape. The ventilation system reduces under-the-hood operating temperature, improving performance and long-term durability of the electrical components.
A crankshaft-driven, automotive-style trochoid oil pump ensures long-term durability of critical engine components.
Environmentally conscious technology. All Honda Marine engines exceed the highest CARB 3-Star rating to meet the rigorous California Air Resource Board's standards.
A rectifier/regulator is standard on both manual and electric-start models. On manual models, you have the convenience of 4 Amps to charge the battery, and on electric-start models, a high-output 10 Amp system.
Allows user to trim the unit for maximum performance and handling.
Trim Range: - 4° to +12°
Tilt Range: 64°
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.
Provides easy access to the forward-mounted controls.
Built-in pitot tube in the gear case eliminates the need to drill holes in your boat for installation.
