The newly redesigned BF40 are compact and full of advanced features, offering the lightest weight and highest speed in their class.
MIGHTY THREE-CYLINDER LIGHTWEIGHT ENGINES
The BF40 are technologically advanced lightweight outboard engines with excellent power-to-weight ratio, powerful acceleration and impressive fuel-efficiency.
4 stroke - 40hp
3 cylinders – 808cm³
Honda BLAST™ hole shot technology with PGM-Fi electronic fuel injection delivers instant acceleration to get you up on to the plane as quickly as possible. It does this by using improved accurate ignition timing, which develops more torque at low rpm so you can rapidly reach cruising speed.
Cruise more, spend less
Our unique lean-burn control ECOmo system adjusts the fuel to air ratio depending on load and speed to improve your fuel consumption when cruising. When your boat is up on the plane and cruising (in the green area illustrated above ) the PGM-FI system can adjust the air/fuel ratio up to 20% by making the mixture leaner.
New engine design
Wearing a new design, the new BF40 and BF50 have been developed for performance. The gear case is extremely hydrodynamic to reduce water resistance and take the advantage of all the engine power.
The High Output alternator delivers a solid 22 amps, which will keep a battery with a 17 amp charging capacity in top condition; and it’ll keep all your on board electronic equipment powered up too.
Not such a drag
The gear case is extremely hydrodynamic and super sleek. The gears within are machined to fine tolerances, reducing friction and contributing to the overall performance and superb fuel economy at high speeds.
Plug and play
The engines are NMEA2000® compliant, which makes it compatible with all other NMEA2000® compliant electronic devices – like navigation and fishfinder systems. Engine data rpm, temperature and fuel consumption can be displayed through multi-functional gauges.
Engine protection and security
Honda outboard alert systems monitor critical engine functions including engine temperature, oil pressure, fuel injection and charging, and will alert the boat user to abnormal operating conditions.
