A german company Duetz makes lots of air cooled Diesel engines - max power I have seen is 190 hp - often used in generators/ air compressors etc...

Here's an article: http://teamscarab.com/news.htm seems Larry Smith's new boats only come with diesels. Does anyone here know or have seen one of these boats before? I have never heard any talk on here about Kona boats, but everyone has heard of Scarab.

New builds and resto jobs are both fun in their own way
