That isn't exactly safe lol.
It was fine with a 400 lb brother in law standing on the hoist....
So far Ive only pulled the motor out.. I was in a bind, it was starting to rain , and my helper wasnt gonna be available for two more weeks if I didnt get this done "NOW".
I picked it out from over the passenger side fender with the equipment the way it was out of the box. It worked out fine, But I still would have liked the conventional "Out The Front Approach."
Anyway ..to answer your Q...Yes 1000 lb is plenty.
