Today I overheated while running and shut it down, but it got fairly hot, over 200. I got the impeller out, and it was toasted, but strange only the back half was torn up. I looked and could only find 3 pieces of impeller (all 12 gone), pulled the t-stat housing, no junk there. Should I pull the risers? One of the pieces I found was in the t-stat housing where the water is distributed to the exhaust manifolds.
Replacement impeller filled the strainer, and it would idle for a few minutes under temp, then it seemed to go straight to overheating.
I picked up a new t-stat, even thought the old one appears to be working ok. It opened at 165-175 in the pan, maybe that's too late?
Other question is, if the sending unit nut is loose, would that make the gauge erratic?
thanks,
Jack
