Hello. I just bought a 1968 Ericson 30. when i got her the rudder was laying on the foredeck. I have the tiller the rudder and the rudder shaft, but none of the internals. Just so happens a friend of a friend is hauling out a 1972 Ericson 29 for salvage. Hopefully i will be able to get my hands on it. my question is will these parts be interchangable and what is a fair price. I have no idea what all of these parts are or how much labor is associated with pulling them off the 29 and putting them on my 30. if anyone could shed some light it would be greatly appreciated.
