BF50

Introduction

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

This high-torque, three-cylinder engine features smooth and quiet performance and very low hydrocarbon emissions.Standard electric start and a digital CDI ignition system provides instant and reliable starting in hot or cold weather. A high-capacity intake silencer substantially reduces intake noise while a resin cylinder head cover takes care of high-frequency noise.  

The BF50 is available in standard, long and extra long shaft lengths allowing for a wider range of boat applications. Honda’s industry leading integrated warning system protects the engine from severe damage due to low oil, over-revving and over-heating situations. Standard on all tiller handle models is Honda’s exclusive multi-function tiller handle, featuring the indicator lamp, throttle control, power trim & tilt switch and gear shift lever all on the tiller handle. The standard freshwater flush port allows easy flushing of the engine to clear debris and salt water, extending the life of the outboard.

Comfortable Cruising

The BF50 features a unique design which positions the crankshaft and flywheel assembly directly above the pivot shaft. This gives exceptionally smooth idle and a reduction in overall vibration for smoother running.

Easy on Fuel

Honda engines are powerful on performance and low on fuel consumption to offer quiet, clean and fuel-efficient operation. The BF50 consumes up to 50% less fuel on average than a conventional 2-stroke engine. So you can go further and stay longer.
