Is it possible to remove the original muffler on a 89 Catalina 30 without removing the galley. I took a long look today and I really do not want to take it apart unless it is absolutly neccessary. I will probbly replace the original with a Vetus, which I believe is much smaller. Now, how hard is removing and installing the new muffler. I managed to remove all but one screw, and I noticed it is fastened with some type of adhesive or epoxy.
