So after more hours than I care to remember stripping, fairing and sanding the bottom in preparation for new barrier coast and baltoplate, I've found something odd. As I was sanding away the old bottom paint from around the prop strut, I found a few cracks peeking through. When I pried at them with my chisel, brittle, almost ceramic like filler kept prying away until I had unearthed a "moat" all the way around where the prop strut meets the hull!

Like WTF mate? What would account for this? So strange! I'm going on the assumption that, as it is center-line, I'm dealing with just glass here. My question is, can I just fill this in with thickened epoxy and go upon my merry way or should I pair it back and do new fiberglass all the way to the edges of the strut?
