Re: Replacing engine mounts

I have had one mount fail under my 3HM35F Yanmar (front port). It was not the rubber to metal bond that failed, but rather the engine mounting bolt which cracked through just above the point where it joined the upper metal plate. It made a ticking noise when the engine idled. The surveyor heard it before we bought the boat, but he could not locate the source. We found it 6 months later. I replaced all four. Later when we had the engine rebuilt, I replaced all four mounts again with no indication that anything was wrong with the existing mounts.
