If you look that post was from 2019 and was the end of Yahoo forums.
They had been going down hill prior but that was when they finally pulled everything that was online as an "archived" file.
Fortunately TF had recognized the need / opportunity and created the TF Library function which made a perfect place to post & search for worthwhile " reference material" files.
In the case of Mainship owners, Marlow Yachts provided no notice when they pulled down a treasure trove of legacy MS files that included searchable BOMs, electrical schematics, part pictures with part #s & source info. When contacted (multiple times) to see if they could be retrieved and taken over by someone and posted on another server, they ignored the contact and wouldn't even respond.
It was only through the help of a diligent MS owner that had download the MS, Luhrs, Hunter part pic files, that I was able to post them here and on my Bacchus website. If Marlow had cooperated we could still have had that wealth of info available to the many MS owners.
The only conclusion I could come up with is Marlow had no, none, zero, interest in helping MS owners in any way. They bought (likely stole) the MS name and thatvwas their sole interest. I dont know if they used any of the MS molds?
