Blast off

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.

Charging ahead

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.

Compact Power

The BF40 and the BF50 are light, compact 808cc three-cylinder engines, with strong torque and exciting performance.

How do we do it? By giving them PGM-Fi electronic fuel injection for easy start up, powerful acceleration and outstanding fuel economy. The long, slim inlet manifold and miniaturised electronic components save weight and space, contributing to the compact slim design.

Better performance: Add to that our unique Boosted Low Speed Torque (BLAST™) and the super efficient lean burn control of the ECOmo system, and you’ve got a very impressive combination indeed.

Works hard, plays hard

Both the BF40 and the BF50 are lively and responsive outboards that will provide dependable performance for water lovers whichever water they ply. Both are NMEA2000® compliant, electronic fuel injected engines with optional Trolling Control – no differences there – this outstanding range of 4 stoke engines feature a host of innovative Honda technology, in a fully new design.
