A life on the water

There comes a time when you’re ready to move up to the next level,and spend more time out on the water.

Maybe it’s teaching the kids how to water-ski or doing some fishing with a few friends at the weekends. Whichever way you go, the BF80 or BF100 will be your perfect partner. They’re reliable, compact, light and have all the qualities you need to get the most out of your time on the water. It goes without saying that if you need them for work, they're very reliable working companions.

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.

Sparkling silver finish

We think something that works beautifully should look great too.

The power within the BF100's slim elegant design delivers exciting performance.

The finish is stunning in Honda aqua marine silver. The sleek, sculpted design is liquid smooth. It looks good just fixed to the back of the boat, but in the water – where it really belongs – it looks even better.

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.

Inside, the gears are machined to ultra-fine tolerances to reduce friction as well as fuel costs.

Our winning ways

From the world's racing circuits, to the waters of the world.

In 1959 we entered the Isle of Man Motorcycle TT race with dreams of winning the world championship. We made our presence felt two years later by finishing first – as well as second, third, fourth and fifth. Today’s machines are proof that dreams can come true, and improving their performance is a continual challenge – and joy – for us.

Track technologies

Proven technology from the racetrack is passed on to our marine engines. Every innovation, no matter how small, is like a trophy to us. We’re always looking around the corner to see what’s coming next.

A watertight warranty

Like our engines, a Honda warranty is the best you can get.

Time for a service. The small wrench symbol will tell you when you need to talk to our technicians.

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.

Four lines of defence

We first anodise the aluminium casing with our patented ‘Double Seal’ process. Then an epoxy primer is applied before the shimmering silver paint and for further protection from UV rays, we apply a clear resin topcoat to finish. Just to make double sure, a sacrificial anode is fitted and all connectors are waterproof. Corrosion doesn’t stand a chance.
