If there were sheets, brochures, articles etc... that are readily available, we would try and have them on this site.
That's not to say they don't exist but no one I know of is waving them like a flag. I look all the time. A lot is stuff we have (think e-bay) and when we come across something new, we try and add it to our collection. You just have to keep searching and get lucky.
I don't think a lot of the older stuff had much material available during production, at least not to the general public. Dealers and actual production employees may have received more technical stuff.
As far as how these boats are put together, the rebuild section contains as much data as any place you could find. This of course is hands on acquired rather than factory spec.
Good luck.
