quote VikkiP:

Dry (a few shots of fogging oil into those cylinders that sat dry for 50 years) reads 65 psi lower, 68 psi upper. I didn’t look up the optimum but that seems about 25 psi lower than I want to see. I’m thinking the rings are probably sticking a bit.

OMC didn’t tend to publish expected compression numbers.
From the notes I have, 70-75 is good for the TN/TD series:
it could come up a little after you’ve run it, so you’re doing well!

What are you used to working on?
