I have a couple or more of these to work on so I started with the probable parts candidate. I intended to get the lower water pump housing out . The old original gaskets were hard and bound to stay in place. The bolts holding the top of the water pump were a challenge by themselves but were removed with penetrant, patience and some heat. I figured the same plan for the lowerwater pump base but noooooo. I broke the darn thing. I was careful , I saw that to much prying could break it. It broke anyway. So on the others : is there a practiced way to remove the base.? These are salt water motors so there is that consideration. I am cautious and, capable and patient just would like to know what if anything I am missing . Besides training .Thank you.
