Isn't engine TBO driven off the engine tach-time and not Hobbs meter
time? Since I don't have a hobbs meter in the Mooney does that mean my
engine is not recording any wear? ;-)

Heh Heh, if it only worked that way. I have customers come in from Mexico
for overhauls at "TBO" with probably twice the actual hours on the engines.
Not very many twins have the recording tach like the Aztec.
