Not only is the design of Honda's BF40 supremely elegant, but it's also the lightest engine available in its class. Perfect for aluminium boats and inflatables, it combines class-leading lightweight, compact packaging, enhanced with PGM-FI electronic fuel injection delivering the precise amount of fuel/air to each cylinder. The result is an easy start and instant throttle response with superior fuel efficiency. Throw in Honda's original Boosted Low Speed Torque (BLAST™) air/fuel ratio and ignition-timing technology, and lean burn control, and your 'hole shot' is vastly improved as more horsepower gets the hull up on plane faster.
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).
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. The BF40's Engine Alert System also uses visual, audio and RPM reduction circuits to alert the operator of overheating, low oil PSI and over-revving, preventing engine damage.
