I would say you overheated it too. I did it once when I put the raw water pump on backwards. I won't do that again. Luckily the motor wasn't hurt at all, I changed the hoses around and the next day everything was great.

If you got a look at the water pres guage before it "locked up", that may be able to help you (or maybe the oil temp...if it was really hot). Any clog in the water line can disrupt flow and if that impellar gets hot enough it will shut the motor down. Happened to me when my water line clogged. It about gave me a coronary! I know you said the impellar looked fine, but maybe it heated up without ripping apart. Not likely perhpas, but that squeeking/squealing sound seems like that to me. Just my .02, alotmore knowledge on this thread than I got.....

sure sounds like it was getting hot. I'd bet the squeal was in fact the impellar. What about your water pickups are they all clear? Are you sure it is actually getting water?
