Fifteen psi difference between highest and lowest compression reading spells trouble. This is usually due to having a carburetor foul which results in a cylinder to run lean. Suggest you inspect that bottom cylinder for scoring.

15 psi is the max that the OMC service manual says you can have. A good decarb may help it . Get a wan light and look into the spark plug hole and see what the cyl looks like.
