Update. The leaking areas are accessable from the q-berth
Went down to the boat this weekend, froze my butt off but it was time well spent. Both of the starboard scuppers that are leaking are accessable from below by unzipping the headliner in the q-berth. The sealing material used does not appear to have the consistency of 3M 5200, it looks more like polysulfide like BoatLife or maybe a different 3M product? It is easily trimmed back with a utility knife, even at 25*. The leaking areas are easy to identify, the black streaks are obvious. It appears to me that be trimming the sealer back and/or cleaning the area back with a dremmel tool, additinal sealer can be added. There is also a 1/4" bolt on either side of the scupper tha I plann on loosening. I'll add the new sealer then re-tighten the bolts. I imagine that the port side scuppers are accessable from the cockpit locker, but it was just too cold to investigate that.
