Good Evening, this post is somewhat older but I am newer and just reviewed. I own number 17 Pearson 530, and I do have a lot of the original documentation, including the original manual that outlines much of the locations and systems. In addition, I am in the process of doing a complete re-fit of her, from hull up.. so I have touched every part of her. If I can be of assistance, let me know. jharrisoncs@gmail.com. Also, just started a website on her as well... svdeviation.com. In the upcoming months I will post much of the documentation and changes as well. Hope that helps.
