Exceptional power & performance
The BF40 is packed with power and exceptional torque. Featuring a unique set of Honda-Exclusive technologies, the BF40 will easily power all of your adventures.
Features
Boosted Low Speed Torque (BLAST)
Honda’s revolutionary BLAST™ technology provides strong hole shot performance, getting the hull on the plane quicker. This air/fuel ratio and ignition-timing technology boosts engine torque at low RPM under rapid acceleration conditions. It’s NMEA compatible, meaning all engine data including speed, fuel consumption, cruising distance, etc can be displayed on the GPS screen.
Best in class charging
You’ll get best in class charging performance with the BF40 thanks to a 17-amp alternator. This means your outboard is able to charge the battery faster and power more accessories, so that you can now run a bit of extra tech on the boat to help you find the perfect catch.
Multi-function tiller handle
The BF40s multi-function tiller handle incorporates a power trim-tilt switch in the tiller handle, so the operator can trim the engine while underway and remain completely focused on the water. It also has a reversible shift lever, which can be mounted on the left or right side.
Programmed Fuel Injection (PGM-FI)
Honda’s renowned Programmed Fuel Injection is controlled by an advanced Engine Control Unit (ECU). Engine sensors precisely control the supply of fuel to the engine, providing easy starting, instantaneous throttle response and superior fuel economy.
Lean Burn Control
Honda’s Lean Burn Control technology, ECOmo, permits combustion to operate on a leaner air/fuel ratio. Sensors precisely measure the air/fuel mixture, ensuring best fuel economy in cruising mode.
Trolling control
Trolling Control is available from BF40 – BF150 & BF200-250 (DBW only). Available on selected Honda outboards, engine speed can be controlled in increments of 50RPM from idle speed to 1000RPM/1100RPM (model dependent). A switch required to activate this feature is available through your authorised Honda Marine dealer as an optional accessory.
