If all nuts are loose and still won't drop it is seized up. That is why they say replace impeller every year, so LU is dropped regularly. If seized use a wedge to split them appart. When I had a 65 hp that was seized I got a wedge from lowes in the garden section made for splitting wood. Use a rubber mallet to tap at it. Just be careful not to damage anything internal. And leave the nuts on a couple threads to catch the LU when it falls free or place a block of wood under it.
