2006 GSX-R600 - Water pump doesn’t come off the engine

I am replacing the water pump of my GSX-R.
I drained the engine oil and the coolant, disconnected the hoses, undid the two 8 mm bolts. But the water pump does not come out. I can feel the pump moving a little bit, when I pull on it, but it doesn’t come out. Part of problem is that is difficult to get a good grab on the pump. Also, I don’t want to damage the pump, because I plan on overhauling it and keep it as a spare.
Any suggestions?
Thanks

Double check everything is truly out via the number of pulled bolts and comparing it to the service manual, then use a rubber mallet and keep tapping around it until it comes out.
I'm thinking that the O-ring on the pump's nose has somehow stuck/bonded to the crankcase and you're just going to have to keep fooling with it.
Just_Nick, BillV,

Thanks for your suggestions/recommendations. The pump has just come out after tapping around it with the rubber mallet for quite some time. I was expecting to see a damaged o-ring, but the o-ring apparently was fine. Certainly the o-ring had been there for a long time, the bike is a 2006 model. I am not really sure about what caused the problem. There was a build-up of dirt behind the pump, but I wouldn't think that the dirt was holding the pump. In any case, the important thing is that the pump is out....
What was the reason you decided to change the water pump.
Leaking ? From where ?
Overheating ?

I am replacing the water pump because it was leaking oil for sure and it was possibly leaking coolant too. I did not investigate the coolant leak in depth, because to me the oil leak and the 15 years of service were already sufficient reasons for replacing the pump.
