So my rudder is water logged. Got a replacement rudder looking for help on how it is to replace rudder. Looks to need some fiberglass repair on area around the hole rudder shaft goes into will supply pictures later wondering how the bushing go onr there are three two larger and one smaller inner ring. Note I have a wheel steering installed and want to add emergency tiller. I see I have to raise the boat to drop old rudder and insert new rudder.
