I have originals of both those schematics that came with my boat. They measure about 24" X 14", and I tried unsuccessffully last summer to find somewhere to scan them so I could load onto this site, if anyone has any suggestions for specialist shops I will try them.
I think the value of the electrical one is limited, since the original wiring is inaccessible in most places, and was of such a low quality that it will need full replacement by the time it is 25-30 years old.
