Solvation should only be done at the very end, after a few dozen rounds of 
shrinking.  Are you working through the tutorial or a system of your own?  If 
you're doing the tutorial, the amount of water molecules is far too high.  Water 
molecules within the hydrophobic core of the membrane should be obvious upon 
visualization (there should only be a few, at most, if the system is constructed 
properly).  Methods for dealing with these stray molecules are described in the 
tutorial.
