E380 Replacing the Engine Mounts

When I purchased my boat I didn't like the look and condition of the engine mounts, particularly the port side ones that were badly rusted. The Yanmar 3J2HE engine has the integral heat exchanger and water pump impeller access on the port side above the engine mounts. So over the years those mounts appear to have had their fair share of raw water splashed over them and had rusted badly. The replacement of the engine mounts was the last thing on my winter lay up "to do list" as I could see it...
