Unfortunately my relatively new (6 years) forward port engine mount is badly corroded, likely from allowing saltwater to saturate it as I change the heat exchanger zinc.
I have decided to have the professionals replace all 4 engine mounts and align the shaft, as having mounts of the same type and age will help quell vibration.

The new engine mounts are in, and they look very robust.
