Honda
BF80 – BF100
Power your adventures on the open water with an engine that gives you 4-stroke reliability and efficiency in a slim and stylish design. These compact and potent engines are just the thing for larger inflatables and sports boats.
Overview
A Forceful Four
Attach a four-cylinder engine and experience smooth, satisfying power – and a whole new level of excitement.
The wow factor comes from the Single Over-Head Cam, 16-valve 1.5-litre engine. It’s got PGM-Fi electronic fuel injection for easy start up, and Honda BLAST™ for powerful acceleration. Then there’s VTEC™ on the BF100. When it’s combined with ECOmo, it not only gives you outstanding fuel economy, it delivers exciting performance at higher revs. These engines are light and compact, and with NMEA2000® connectivity you can see why they’re a big favourite with powerboat enthusiasts everywhere.
Functional design
Above the water both engines are super-slim for a four-cylinder 4-stroke. The removable engine hood fits snugly over the engine and all its working parts to provide excellent engine protection throughout. Below the water the hydrodynamic gear case has a low drag coefficient. You can see the difference right away – it’s so slim – providing better fuel economy at higher speeds.

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.

One Step Ahead of the Rest
The unique Honda VTEC technology (Variable Valve Timing and Lift electronic Control) optimises engine performance and reliability throughout engine rpm range (only on BF100).

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.

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 ) you’ll be saving up to 20% of your fuel by making the mixture leaner – saving you money.
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.
