Hello All,I have 1981 Catalina 30' that has fairly significant movent in rudder shaft causing gelcoat to crack where emergency tiller attaches. I dropped the rudder about 5 inches in the yard last weekend to get a better look and it appears that where the rudder shaft enters the rear transom there is a fibberglass tube it fits into? The shaft does not rotate freely in the tube and I beleive that the tube was originally glassed to the outer hull but has come loose and ceased to the shaft? This might also explain a creaking noise that I am hearing while underway. My question is: has anyone had similar problem with Catalina rudder and if so what is fix? Can I get new bushing(original fiberglass tubing) and if so is this supposed to be glassed to the hull? Please help. Thx
