Re: destroyed impeller
Might be a good time to clean the passages. In my other life as a chemical engineer we find that as little as 1/32" of scale reduces the heat transfer by 20%.
If you suck 1 gallon of white vinegar (< $3 at a supermarket) into your raw water side and leave it overnight it should help de-scale the cooling passages.
I try to do this periodically with my raw water cooled engine.
