I have seen several boats listed this way. There will be a Mako, for instance, minus all the factory stickers and tags, and it will be listed as 21' FISHERMAN'S CUSTOM CENTER CONSOLE. Then there will be a bunch of pictures, and sometimes they tell you it was a Mako shell before the rebuild, sometimes they don't.
I dunno... I think I'd rather buy a rebuilt AQUASPORT than a CUSTOM, but I guess it depends on the quality of the rebuild.
IF you are trying to rebuild to sell, maybe you should take a poll. If in doubt, the name brand DOES have name recognition going for it.
