Hi, Marcelo,

If your stern tube has been replaced, I don't know what they did. 
Perhaps they replaced it with a fiberglass tube.

The stern tube should be held in place by caulk. If the caulk holds. 
then unscrewing the cutless bearing housing shouldn't turn the tube. Nor 
should it be feasible to pull out the stern tube with the cutless 
bearing housing.  That's the purpose of the caulk, not waterproofing.
