THE ENGINE IS STILL THE SAME. SINCE IT IS THE BF 250, but with all the improvements that Honda has brought over time. The look has changed and the performance has improved. The new look is significant, because, for the first time since Honda has been producing outboards, customers will be able to choose a livery that is different to the traditional grey colour schemes.

Beneath the seal cover, however, a lot of new things have been introduced to produce even better performance. It has a lot of power and produces a lot of thrust. We did over 47 knots top speed and just three seconds were needed to start planning. So, it’s clear, there is torque and power. I was on board a H26SD, with SD standing for “Sun Deck”. An open-style boat that is 7.55 metres long overall, with a small cabin for two people. It is made by Ranieri International exclusively for the Honda sales network. But it is something more than a package, because the logo is that of the Japanese firm, so the 4XC Design, but the rigging is also made by Honda. Everything pre-assembled and fitted out, so as to avoid mistakes when it is being put together.


Every model comes out of the yard in Soverato with the precise indications for the Honda sales network. There is also plentiful information about which propeller to fit, and how high to install it. And then there are the displays. They are the fruit of the synergy between Honda and Raymarine. Very beautiful, and not just in terms of the look. Despite the perpendicular light on the screen the visibility is exceptional, and the positive characteristics aren’t limited to that. Thanks to the NMEA portal all the data comes from the engine, including the time spent in motion and snap fuel consumption levels, but above all great work has been done on the display graphics.


The Honda BF250 is fitted with ECOmo, the lean carburetion system which has been developed to reduce fuel usage as much as possible when you travel at a constant speed.

The ECOmo intervenes particularly between 2000 and 4500 rpm, and in a few words, increases the amount of air in the combustion chamber, so as to save fuel. The new display that is already mounted on the dashboard, has a very intuitive graphic. The rev count is actually shown highlighted by a coloured circumference. When it is green, that means that the ECOmo is working and that fuel usage is very low, whereas when it is red that means that lean carburetion isn’t working. That way, even when you jump across the waves on a slightly rough sea, you just have to take a quick glance at the instrument screen to work out if your consumption levels are low. And then the high consumption levels aren’t actually that high, if you take into account that to do 40 knots you need around 100 litres per hour, and more or less 2.5 litres per mile. But in the ECOmo band between 2000 and 4500 those figures are even lower, because litres per hour vary between 30 and 77 and litres per mile nearly always stay under two.


The hull by Ranieri behaved extremely well. I liked how it reacted on the waves, and the way it protected from the spray. And indeed, with waves of 40 centimetres, the hull didn’t suffer at all, not even when we pushed up to 6000 rpm. The boat was always very stable, and it always made good headway, even when taking the waves on the bow. It was also great to have the deck dry. The waves weren’t excessive, but the wind was more challenging. At least twenty knots, with gusts a bit more than that. That should have been quite enough to get wet, but I didn’t. Of course, you have to take some precautions, but if you don’t make a bad mistake with the throttle and the wheel, you won’t even get splashed. And finally, like all self-respecting packages, it has a competitive price. For the base version, boat and engine together, the list price is just over Ä 60,000. Then, if you like there is a long list of optional extras: from flaps to the hard top, to the teak on the deck, to the underwater lights, but even if you are taken by a compulsive optional buying urge, the cost still stays very appealing.


The small cabin can also be used for short-range cruises or as a place to change bathing costume during a day on the sea.
