Catalina 36 Olympia, WA
Addressing neglected maintenance on our 1987 Catalina 36. The boat was re-powered 2003. This weekend found the rear port motor mount was seriously corroded. (See attached images of the two rear mounts port and starboard.) The other mounts do not show the same signs of corrosion or failure. Is it necessary or recommended to replace all four mounts, or could I get by with replacing just the rear mounts, or just the one. I think I know the answer that if one, really need to bit the bullet and replace all.
