Hi Boiler70, You probably have an older boat that never got the rudder mods that solved all the old problems years ago. Rick has not sailed a newer Mystere so is still under the misconception that current Mysteres have rudder problems. That has not been true for several years; in fact, the rudders are excellent now. You should contact Mystere (see the link at this site) and describe the year boat you have and let them know about your problems. I will not be surprised that they send you the parts you need for free because Mystere has excellent owner service. If you need any help, contact me directly and I will assist you. Take care, Mike<br><br>
