Honda Marine Outboard Motors
BF40

Honda’s completely-redesigned BF40 and BF50 EFI four-strokeoutboard engines have arrived!

Retaining their class-leading lightweight and compact styling,the new engines are enhanced with electronic fuel injection,Honda’s revolutionary Boosted Low Speed Torque (BLAST™) air/fuel ratio and ignition-timing technology, and Lean Burn Control to deliver powerful start-up and acceleration together with outstanding fuel economy during cruising.

BLAST™, along with a newly-designed, streamlined gear case and other improvements, contributes to greater acceleration and a higher top speed, while Lean Burn Control results in a 22% improvement in fuel economy over the previous models.

Battery charging capacity has also been increased to 17amps – over 1.7 times that of the previous BF40 and BF50.

The new models are compatible with Honda’s latest general purpose engine diagnostic system (Dr H) and also feature a new one-touch plastic cap, which permits easy inspection of anode wear inside the engine, for significantly improved ease of maintenance.

Consistently leading the world in environmental performance, Honda has also managed to reduce noise levels by 1.0dB over previous models through such improvements as a longer exhaust pipe and an optimised rib design inside the upper portion of the extension case.

Both models exhibit outstanding environmental performance and exceed: 2008 CARB emissions standards – the most stringent in the world; US EPA standards for 2006; and domestic Japanese voluntary regulations.

As is the case with every other model in Honda’s outboard engine range, the new BF40 and BF50 also achieve the Outboard Engine Distributors Association’s (OEDA) three-star rating for ultra low emissions.
