BF40 – BF50
The newly redesigned BF40 and BF50 are compact and full of advanced features, offering the lightest weight and highest speed in their class
Overview
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 AND PLAYS HARD
If you’re out fishing or just having fun blasting across the water, you’ll still want the best engine for the job. But which one?
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.

Key Features
Up, Up and Away!
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.
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.
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.
Warranty
6 Year Limited Warranty (Pleasure use only), there’s a simple reason why you see so many older Honda Marine products still hard at work: they’re built better to last longer.
This is supported by the longest and most comprehensive guarantees you’ll find anywhere. For example, every one of our outboard engines is backed with an industry leading 6 year domestic warranty (and 2 year warranty for commercial users), covering both parts and labour.
