TOPIC: Dorsett St Juan Renovation

I have a 1963 Dorsett St Juan. Has the original (I think) Volvo Penta engine and the IO Aquadrive. Engine runs, but has not done much since 1996.......same with IO. Can I still get parts for old Volvo Penta engines? Can I still get parts for the Aquadrive? My boat yard says that I should consier installing an inboard and modern engine. I am sure I have seen some posts on the web about Dorsetts with complete inboard, but cant find them now. Did Dorsett provide an inboard option for the St Juan? Has anyone come across a inboard conversion from an IO on a Dorsett?

please add a picture or two. we like pictures. Is it a San Juan? How long is it. I don't recall seeing anything for dorsett's as a straight inboard but I am no expert.
