They are made by Rob Pols. This is the same (Dutch)guy who home made the very very nice lower units (pics on my site) But they are pretty big. About 100 cm. For a 11 or 13 CC engine
On page one the second to the last picture has a picture of an outboard on a stand. What kind of lower unit is that and where do I find one? also where do I get one of those mercury cowls that covers the motor?
