Very interesting read. I am not quite ready to make the plunge, but when I do, Scania is top of my list. They have been doing ferries and tugs in Europe and the Netherlands for years. Light, efficient and powerful. To think their 12 Liter 6 cylinder is putting out 250 more HP then my 12v-71s! so cool. I have run them, and they are beastly. If you want more info, I have a guy...
