in-line 6 overheating problem

[moneyhole]

I see now why my water pump is bad, as I was taking off the lower unit I noticed some areas that had been epoxied and painted over. Guess what, the whole trim tab casting on the upper half of the motor broke off. I traded the boat with a horse trader. Can this type of "pot metal" be welded or am I just up the creek wihout a paddle. I'm going to post a pic of it in my album. If any one has any ideas, suggestions, solutions or other ideas than sinking her, let me know. I've contacted the fellow I got the boat from asking to reverse our trade...doubt I get far with that one. Live & learn.
