2018 Honda Marine BF40 L Type

The BF40 and BF50 are an outstanding combination of Honda’s legendary four-stroke engineering and our latest outboard innovations. The result? The lightest, most compact engines in their class. And because they are from Honda, they’re loaded with the unparalleled features and technology you want.

Like BLAST (Boosted Low Speed Torque). It’s activated by a quick movement of the throttle for vastly improved hole shots.

Features may include:

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

NMEA 2000 protocols allow engine data to be displayed on NMEA 2000 compliant dashboard electronics, like sonar and GPS.

Lean Burn Control® increases fuel efficiency by allowing combustion to operate on a leaner air/fuel mixture. At cruising speed, this engine runs on as much as 20% less fuel* than others in its class. *Based on the EPA's Specific Fuel Consumption Mode.

Boosted Low Speed Torque, or BLAST, improves acceleration at low speeds. A quick movement of the throttle control activates the BLAST® system, advancing the ignition curve aggressively. "Hole Shot" is vastly improved as more horsepower gets the hull up on plane quicker.

Programmed Fuel Injection delivers the precise amount of fuel/air to each cylinder. The result is easy starts and instant throttle response with superior fuel efficiency.

There's always plenty of electric power with the 40 and 50hp. Honda’s innovative technology enables these engines to put out nearly twice as many charging amps as the competition’s.

Designed to get you going faster, the BF40 and 50's gearcase reduces drag, greatly reduces hull porpoise and minimizes spray, thus increasing acceleration and top speed.

A longer anti-ventilation plate helps trap water flowing to the propeller to minimize porpoising

A streamlined front and longer bullet reduce drag for enhanced acceleration and fuel efficiency

A front splash plate reduces spray from the hull bottom, maintaining a dry deck above.

Adjusts to a comfortable angle for easiest hull manueverability.

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.

Tiller models feature a new 4-lamp warning system built into the tiller handle, while remote control models deliver alerts via messages through Honda’s multi-function digital gauges or a special indicator built into the unit’s control box.

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

Because of Honda’s elegant design, the BF40 and 50 are the lightest engines in their class. Perfect for aluminum boats, inflatables, skiffs and flats boats.

Environmentally conscious technology. All Honda Marine engines exceed the highest CARB 3-Star rating to meet the rigorous California Air Resource Board's standards.
