My C152 has about 7500 TT logged but the hobbs shows about 3900. Does
this make any sense? Perhaps the hourmeter was replaced?

Exactly. My Cessna is on the third Hobbs, but the tach keeps going just
fine. Tach shows about 4400 and Hobbs is 150. Just go back and look at the
logs. Hopefully you will find entries recording the change of the Hobbs
meter.
