Water Leak - W111 M180 pump or housing?

[ScooterABC]

I am replacing the water pump in my 1963 220Sb. Looked to be straight-forward enough until I found out that the bracket for the York AC Compressor was in the way of two of the bolts holding the pump on. So I removed lots of bolts to move the compressor and bracket slightly out of the way. Then I discovered that water is leaking out of one of the holes that previously had a bolt going into it holding part of the compressor bracket in place. Should water be coming out of this hole? Should there be some sort of gasket or seal on the bolt and/or bracket that is sandwiched between the bolt and the housing? Or is this "normal"???

Please see attached pictures.

Thanks
