Has anyone ever had a leak from the bottom of the rudder post? If so how do you go about fixing it? It's a decent size leak on a 1984 Catalina 36 just launched it the other day and I couldn't figure out why the bilge was filling with water, I tore the whole boat apart trying to find the leak and I finally found it at the stern where the bottom of the rudder post is. Any help would be greatly appreciated.
