Tom,
There was indeed a previous I/O on that boat. However, when I purchased it, no engine nor drive were there. Only the hull.
We need to patch-up the transom in order to reinforce it. It will then be drilled to the drive dimensions in the upcoming weeks.
It seems the same as been applied in Sweden for that Lancer project.
Here the very intersting link :

I keep you posted.
