Cruising gently I can get down to about 40 litres an hour (that's paying a lot of attention to the fuel consumption gauge and not the speedo!). I had, until recently a 7m Solent with a 225hp Suzuki (same block as the 250) and I don't really notice a huge increase based on a day generally razzing around. The 9m hull, compared to the 7m is a vast improvement though (7m and 7.5 are same hull, one just slightly longer, 9m is a totally different design). I found the 7, (and indeed the 6.5) to be quite slammy and "sharp", whereas this is like sitting on a motor cruiser; doesn't slam at all, just cuts through anything that gets in the way. The 9m is considerably beamier as well. The finish on this one is a lot better than my 2005 7m. If you do buy one, get a 300 on it
