Has any one ever come across an engine that has torn all four motor mount rubber pads up and partially out of thier aluminum enclosure cups ? None of the obvious possible situations seem to have occurred such as a trip on the beach, capsize, engine developing excess amount of torque, guess I'll reread the Perfect Storm and take up couch potato activities.

Re: CD25D engine mounts
Paul,
I just finished reading "The Perfect Storm" this past weekend, read it in two days! Good story, hope I NEVER run into those kind of conditions in Long Island or Fisher's Island Sounds.
As far as the engine mounts, look closely at the rubber itself. If you can stretch a piece of it between your hands and it appears to be full of cracks, the culprit could be ozone. Ozone is death to rubber. You shouldn't have a lot of it in an engine compartment unless you have a LOT of electrical equipment in there, but it will age rubber over the years. Of course, the other culprit could be shaft misalignment and the resulting excess vibration. Sounds like you have to replace the mounts anyway, and when you do that you will have to realign the engine to shaft. You can replace the mounts while the vessel is on the "hard", but you can only align the engine to shaft when the boat is in the water. Fair winds and following seas...
