I have the same problem. Seems to be coming from the starboard bow corner of the port bilge section, and / or from a crack about 2" off the bilge botom, and 6" from the bow vertical section of the bilge. I used an epoxy putty stick which worked pretty well, but the water was migrating around under it with just enough force to create "bubbles" in the putty. I let that harden, broke open the bubbles nd packed them with 4000, then smeared 4000 over the whole thing, and that has really slowed it down. Am thinking of getting in there after pullout this Fall and grinding the whole thing out to see what is going on in there. I have the feeling that it will take me into the centerboard trunk which means jacking it off the trailer.....fun, fun. fun!
