Yes, it has been done. Remember guys doing it a couple of times over the years. Best if you have a stand (not lift). This way you can get a floor jack under the motor to aid in lowering, and then repositioning. If you do not have stand, search 'home made' stands on this site. I and many others have built very strong, dependable stands out of common lumber for about 30 - 40 dollars.
