Welcome to the forum
I have not had any problems with my Yanmar engine mounts, but I have met a few boats that have.
There is an Australian company that makes very good replacement engine mounts, that seem much better made for less money than the originals.
They are called Polyflex or something similar if you go to Google Australia you will find them.
If you have problems I will try a search , but my internet is very slow from the boat.
There was a article in PBO a few years back about a Yanmar owner that made the switch to these mounts ,successfully, after experiencing a short life with the originals.
