Has anyone replaced their rudder with the "Newrudder" of Florida. The time came to replace the rudder that had split because of freezing as best we could tell. Rusty drip coming out for days. One other question, the top of my rudder post (Catalina 30) is open and I could see water in the post. Should there be something to prevent water from entering at this point. I do not see a drain for water that makes it through the cockpit access to the steering quadrant (other than my rear bunk). Where are the rudder stops located? Have not found a picture on the net but I recall seeing one once. thanks
