1976 115 h.p. evinrude compression info.

[raveon]

Going to do a compression test on the 4 cylinders. Would like to know at that age of motor what the P.S.I. should approximatly be? Also in what P.S.I. range should all 4 cylinders be in before I sh. consider re-build or "good anchor"?
Motor has sat a couple of year but before that started & ran as it was out of the showroom.

compression guages are all a little different, procedures are different. i would want to see atleast 100 psi, and all cylinders within 10% of each other.
