I think I will run this by everyone...seems no one is familiar with this at the Irwin owners site. I am looking for information with regards to replacing the bottom rudder bushing in my Irwin 30...I have consulted the Irwin Yachts site, got some helpful info from Gene Gammon with regards to materials used and fit, but have yet to find anyone who produces this item. There is about 1/2" play at bottom bushing, and a bit more then that at the brass bushing in cockpit deck where the rudder shaft fits to the tiller. If anyone has any information regarding this issue, would appreciate any help. Thanks, all insights appreciated.
