Cast aluminum, by its nature, fails catastrophically with almost no deformation to warn you. Stainless steel will deform providing advance warning long before failure. We have made this part so robust it is unlikely to ever fail. In addition, a stainless
tiller head eliminates the corrosion problem inherent in having an aluminum head mounted to a stainless steel rudder post. With stainless against stainless any galvanic corrosion problem is eliminated.
For use on any Catalina 30 with wheel steering built before September 1986 through hull number 4725.
Remember that your boat was built by hand. Every rudder was installed in its hull and marked for length. It was then removed and trimmed. The
tiller head casting was fitted and holes were drilled individually in the rudder shaft to match the holes in the casting. None of this work was done by robots. None of it was digital. It was accomplished by guys carrying around tools and rudders. Expect some amount of misalignment that will vary from one boat to the next.
You may need to ream the holes in the tiller head or rudder tube to achieve a snug fit. We have purposely not made the holes oversize as this would introduce excess play into the system.
