Agree with Ken. Chasing the old threads could work if enough is still left from your extraction. Or Drilling out the old threads and tapping a size larger diameter thread should work as well. A Machine shop can do this in their sleep.

The set screw on the Donut nut were seized so they got drilled out. The rudder post threads fared fine but the Donut nut needs to be changed. Does anyone have a source for these or an alternative? Sent an email to Holland Marine but am not hopeful. Thanks for any help, Carl
