I've seen this countless times. Few blades left on an impeller and the engine doesn't even run warm at cruise rpm. Each time it confirms two things to for me, 1 the "Lehman's are prone to over heating" statement I hear from time to time is an urban myth. And #2, it's good to run your engine up towards full rpm once in a while and leave it there for a few minutes or so to see if the temps climb indicating a possible water flow issue.
