I had a similar experience right after I purchased Anne, first indication of issue with the impeller was as you said a different sound. We had no overheat alarms just a much more pronounced exhaust sound. This was with the TMD-22. Lesson for all is to listen to your vessel...she will tell you is something isn't right.

We had an overheat condition on our engine (Yanmar 4JH3-HTE) and the alarm light or buzzer did not sound. I checked the parts manual and the temperature sensor is a 100 oC sensor. I noticed the gauge was over 80 but close to 100 oC and quickly anchored and shut down the engine.
