Motor Mounts

Motor Mounts

The red mount on the right is an older style Westerbeke/Universal engines factory motor mount. They are well designed, robust and do a very good job of isolating vibrations despite their rather expensive price tag. That red one has 2782 hours on it and the two failed mounts to the left are low hour mounts that had already been replaced once before. There are features of the Westerbeke/Universal mount that make them well worth the money:


1) You can not twist the stud inside the mount because it is welded directly to the mount cap.


2) The feet are encapsulated in molded rubber helping minimize noise and vibration transmission.


3) The metal cap prevents engine oils from eating away at the rubber by shielding it.


In short I am not a big fan of the two mounts to the left and I have seen the same type of failures repeated prematurely a number of times.

Points well made, but don't think the Westerbeke won't break. I had one break after about 250 hours on it. No doubt caused by a severely imbalanced Max Pro, which was no doubt caused by heavy barnacle growth and loss of nternal grease. In the meantime, Globe urethane mount literally turned to dust. No longer manufactured by Globe- I wonder why.
