I suggest that you contact Shane Walace over on the main boad as he has a Neptune and seems to be the guy to talk to. I am going to lift my 24 off of the trailer tomorrow and drop the keel out (if I can figure out how/if it comes out). I don't think it is swelling but it seems that I might have a leak coming in from around it. I'll take pics of the process if it will help anyone. Have you found any info on how to remove the keel?
