Cracked Transmission Mount. Could this be the problem?

I hope you know the answer to that. The engine really puts pressure on the mounts. Take any powerful electric motor and hold it in your hand. Turn it on and you feel that snap as it kicks on. Many are hard to hold. Some old drills would literally jump out of your hand. That snap and the cracked mount let that engine move too much. I have had a mount fail on an old honda and the axles will pull out easily. Have it welded or brazed or replaced and the problem dissappears.
