[C320-list] Perkins M30 motor mounts

[Alan Goodman]

Someone recently asked about replacing Perkins M30 motor mounts.  Torresen Marine (well respected shop on Lake Michigan in Muskegeon MI) replaced last summer the mounts on 1994 hull 67 after 975 hours.  One had failed and the other three were very worn.  The price was about about an even grand - $360 labor (approximately 4 hours) and $625 for the four mounts (UNIVERSAL 303062).  This part is known as an 'isolator' in Universal speak, not motor mount.  Also, the Perkins engine requires an isolator with an unusual diameter stud.  It literally took Torresen more time to locate the mounts than do the actual install. Interestingly (and contrary to general wisdom), the front and rear mounts are the same (I questioned this and Torresen says this is correct when using this particular isolator).  Hope this helps.
