The newly redesigned BF40 and BF50 are compact and full of advanced features, offering the lightest weight and highest speed in their class
The BF40 and BF50 are technologically advanced lightweight outboard engines with excellent power-to-weight ratio, powerful acceleration and impressive fuel-efficiency.
Features to suit a variety of boats.
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.
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.
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.
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.
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.
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.
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.
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.
Trusted technology from our car and motorcycle engines goes into the electronic fuel injection system, delivering better performance and economy.
Power trim and tilt allows you to find the sweet spot, and tune the boat for better economy and performance.
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.
Precise control at slow speed is just as important as high-speed handling, especially if you're fishing. The optional Trolling Control will simply adjust the speed through increments of 50rpm - making it ideal for fishing.
Here are the engine choices available to you.

Improving the quality of our own lives means nothing if we don’t consider the living things around us first. And when it comes to the marine environment, there’s simply no excuse for allowing fuel from boats to pollute our oceans and waterways.
Soichiro Honda had a simple idea to make outboard engines cleaner, quieter and more friendly towards aquatic life – he made them 4-stroke. It was a solution that made Honda pioneers in marine engine technology, but more importantly it made us more responsible towards this fragile environmental resource.
Clean, clear water to enjoy whatever your sport may be.
1. A patented double-seal anodising treatment to the aluminium alloy base. 2. An epoxy primer undercoat. 3. An acrylic aqua marine silver paint. 4. An acrylic clear resin topcoat.
The reason is clear: better salt water protection through better anti-corrosion technology and superior servicing with specially trained Honda technicians. Every Honda Marine customer has the support of a domestic or professional warranty, as long as you stick to the service schedule. It will maintain the same value throughout its warranty period. That means your last day of cover is as good as your first. We think that’s pretty unbeatable too.
We first anodise the aluminium casing with our patented ‘Double Seal’ process. Then an epoxy primer is applied before the shimmering silver paint. For further protection from UV rays, we apply a clear resin topcoat to finish. And to be doubly sure, a sacrificial anode is fitted so all connectors are waterproof. Corrosion doesn’t stand a chance.
Engine reliability is essential if you live and work on the water.
