Stock compression on 1984 Johnson 75hp?

[kryan2]

They had two heads available...high compression and low.

My 3cyl put out 150psi on all 3. What was the original out of crate compression?

I think OMC never published compression values for their motors, just tolerance from each other.
The 150psi on all three certainly looks excellent. I would not worry.
