Got a '86 BlackMax 175. Trying to put in a new water pump, but I can't get the lower unit off. I have removed the anode and bolt underneath, the two nuts underneat the cavitation plate, the front nut, and loosened the two side nuts. It will drop down about 1/8", but the front keeps binding on what looks like that front stud. The washer underneath had rusted out so I figure the rest of it can't be in too good a shape. Soaked it down with WD40. Tapped on it with a hammer, tried heating it with a torch, still won't budge. Help?
