The compression for a 1984 70 hp Evinrude outboard motor should typically be between 100 and 130 psi per cylinder. It's important that the compression is relatively consistent across all cylinders, with no more than a 10% variance between them. If the compression is significantly lower than this range, it may indicate issues such as worn rings, damaged pistons, or other mechanical problems. Always refer to the specific service manual for your model for the most accurate specifications.
