I have 80lbs on the top and 72lbs on the bottom. What should it be? Am I good here?

According to OMC, variation between cylinders should not be more than 15 psi. Sounds like you're OK.

It is good that they are close together like that, but not so good that it is that low. If it runs good, keep running it, but you will need a rebuild soon. That motor is pretty worn.
