BF40

Powerful Acceleration and Outstanding Fuel Economy – Made Possible by Advanced Control Technology, Compact and Lightest in Class


Features

LIGHTEST IN CLASS
Honda’s elegant new design is the lightest engine available in its class. Perfect for aluminum boats and inflatables.

BLAST
A quick movement of the throttle control activates the BLAST TM 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.

ECOmo
Along with Honda’s Programmed Fuel Injection, the BF40 incorporates Lean Burn Control technology, which allows combustion to operate on a leaner air/fuel ratio than stoichiometric air/fuel. An O2 sensor, together with the ECM, precisely controls the air/fuel mixture for the best fuel economy at cruise setting. The mode in which lean burn control is used during cruising to achieve higher fuel economy is referred to as ECOmo (Economy Controlled Motor).

NMEA2000 COMPATIBLE
The BF40 can communicate with onboard electronics to deliver a wide-range of information to head-unit displays. When networked with a Lowrance HDS unit, for example, engine data such as speed, revs, temperature, fuel usage and other data can be displayed on the unit’s screen.

HIGH PERFORMANCE GEARCASE
Designed to get you going faster, this all new gearcase reduces drag, reduces hull porpoising and minimises spray, thus increasing acceleration and top speed.

SUPERIOR BATTERY CHARGING
There's always plenty of electric power with the BF40. Honda’s innovative technology enables this engine to output nearly twice as many charging amps as the competition’s.

3 POSITION TILLER HANDLE
Adjusts to your comfort for easiest hull manoeuvrability.

ENGINE ALERT SYSTEM
Uses visual, audio and rpm reduction circuits to alert the operator of overheating, low oil PSI and over-revving, preventing engine damage.

CORROSION PROTECTION SYSTEM
A patented 'Double Sealed' multi-layered paint process. Sacrificial anodes and stainless steel technology, along with water resistant connectors, all enhance corrosion protection.

EASY MAINTENANCE
Easy 'screw-type' valve adjuster sytem requires no shims and reduces maintenance costs. Easy access side-mounted oil filter and oil filler make for easy maintenance.

MIKUNI INTAKE SYSTEM
Honda’s BF40 engine features the lightweight Mikuni long tube intake track system, which helps build low-end torque.

800 RPM TROLLING
Another great advantage for anglers, Honda engineers reduced the trolling speed of the BF40 from 950rpm to 800rpm.
