Possibility of bits of rubber from failed old pump in the cooling

Possible if the previous owner had an impeller give out, or this one
is getting ready to go. At this point I may go ahead and replace the
impeller on general principles. All of the other easy stuff has
already been checked as far as I can tell.


But if the engine checked out with a heat gun as you say, confirming a
normal reading on the helm temp gauge, it wouldn't seem to be an overheat
problem caused by impeller bits or any other cooling system malfunction.
