OK, well let’s start with is this a long or a short shaft engine?  The arrow is pointing towards the extension piece and the water pump/driveshaft seal tube.   I really don’t think this part is hold things together/stuck.  You have removed one of the brass shift rod connector screws competely (#50), correct?  Have you tried rocking the gearcase back and forth using two large/but dull/blunt screw drivers?  Again, please be careful, do not distort/gouge up those mating surfaces while gently prying.  I fear that the upper driveshaft splines may be rusted/seized into the crank splines, sure hoping I am wrong.  Keep working that gearcase with the two blunt/dull.   screwdrivers/pry bars.

If the splines are stuck, eventually the driveshaft will pull out of the gearcase through the impeller housing.  In other words, the gearcase will come down but leave the driveshaft behind/stuck into the powerhead.  Normally, I would see back away from this situation and just put it back together.  But, in your case, the engine has a cooling problem, so that water pump needs to be inspected/addressed.  So, there is really no other option than to get this gearcase off.  But again, take great care not to gouge up those surfaces while prying.  Perhaps you can wedge some wood shim stock up their so you will be prying against that.
