M_Boats: keel is getting stuck

I have not posted in a while and was not sure how to, so i replied all to a rececent thread. I hope it works. I have a 2013 M17 and have been having trouble with my keel getting stuck and not dropping down. It's in the shop now. They made sure there was not debris causing the issue. It seems to be making contact with the trunk behind the pin.  Can anyone suggest a fix for this? Thanks,Ron McNeilPhoenix AZJackpot  M17 #675
