Water pump engine mount 440

Well I just want to see what kind of shape its in. I read a post about the 440 source water pump housings having a very poorly design that restricts flow. I have been having a lot of the same symptoms mentioned so I decided to take a look. It looks ok to me but it and the fins on the water pump are pretty corroded so I don't know if that would make a difference or not. The pump still turns nicely
