Water in Bilge Coming from Keel, or ?

[Geoff H.]

I just joined, having been lured by the fascinating conversation about Formosa sailboats. My intention was to join that conversation, where I can passionately discuss both the pro's and the con's. (I love my Formosa 51, but love is a dangerous thing.)
But now I have a more pressing concern, and am hoping someone can help shed some light. For quite some time there's been a stinky water accumulation in the sump box that sits in my bilge under the engine - it's a glassed-in box cut into the keel that sits right under the flywheel of my engine - I think it was added by someone post construction?? Anyway, I've always believed that the water came from somewhere inside the boat, and I've chased and repaired and rebuilt everything that was ever suspect.
I just discovered that water was seeping from a screw used to hold a bilge switch in place, (just above the cutout box and next to it) and I removed it and water came gurgling out, and it has continued to do so for several days since. It smells, (like resin??) but is otherwise clear. WTF??
I now have attached a hose and pump and have been sucking the water out, and it has now slowed or maybe stopped. I believe a little water may also be seeping into the box from the bottom of the box itself.
Any thoughts?? This is freaking me out pretty good to say the least?
No one I've asked knows of any other Formosa with a bilge sump box cut into the keel.
The shipwright at my boatyard says to just reseal with epoxy and forget about it; that the water has just traveled from forward through voids to this spot, and that it happens. REALLY?

I'm worried.
