While in the Navy I used to watch the divers remove and install propellors on the subs. They would have a crane lower a very large crows foot into the water and then place a 15 foot breaker bar onto it. They would then place an extremely large scale on the crane hook and run a cable off that to the end of the breaker bar. If the nut did not pop loose at the propper reading on the scale they would keep the strain on and place a small explosive charge on the nut. This almost always worked. Hope this helps.
