I have to replace my rudder bearings on a Jeanneau Rush. Has anyone done this before and can give me any tips? What to look for? What to avoid? I'm thinking to fit new Jefa self adjusting bearings but I'm afraid I cannot work from inside since it is simply not possible to crawl through the hull to reach the aft end where the rudder shaft is (I wonder what Jeanneau thought while designing the boat). Advice? Thank you.
