If you're referring to the little hole down at the bottom of the impeller in the crankcase cover (not the water pump cover), no that is not normal except to say that your water pump seal is gone. Plenty of posts to tell you what to do from here, just do a search. I just replaced mine but I did both inner and outer. Most people will tell you to just replace the outer which is much easier and less involved. Mine's a '98 so I wanted to upgrade to the '99 shaft anyway. Good luck.
