[C320-list] replacing motor mounts

[HOLLY DAVIS]

Rick and John,
Here is the response from Westerbeke about the motor mounts for my Westerbeke 30B three engine on my 1995 Cat 320.
Good Morning, There was an issue with some engine isolator adjusting studs (12mm diameter studs) fracturing (front engine isolators). This was attributed to excessive tightening of the stud’s lock nuts and engine vibration. We are unable to determine if the previous owner had the front engine isolators replaced without having the engine serial number. Original front isolators had 12mm diameter adjusting studs and the replacwements were 16mm diamater. Measuring the diameter of the front adjusting studs will quickly tell you if these were replaced with the larger diameter. The isolator with the 12mm studs is pn#040621 for front isolators and pn#303062 for the rear. The front isolator with 16mm adjusting studs is pn#036339. Rear isolators were not changed. Replacement front engine mounts to accept the large suds are pn#040565 and #040567. All the isolators mentioned are still available.

I will go down to my boat this weekend and get the serial number of the engine and/or measure the adjusting studs and try again to get a couple of comped isolators.  Otherwise I will purchase and keep you posted.  The more I look into it, replacing the mounts doesn't look too difficult, but aligning the prop shaft with the engine looks tricky.  Is it?
