Greetings, We are the owners of a 2001 50' Bavaria shallow draft version, 5 cabin. The time has come to service our rudder system, I need two replace the aluminum shaft tube, bearings, lip seals and hose, (all the serviceable parts). I contacted Jeffa with my year and model and say they have no info on my vessel. Has anyone here replaced these parts and how did you determine you ordered the correct parts? Thanks, SV/ Amy Renae
