I'll go ahead and fly the flag on this one

My factory-trained mechanic said the compression numbers should be within a few pounds of each other-- which is more important than the number itself. He declared my old Evinrude 150 in "new" or recently overhauled internal condition with compression just over 100# in ALL 6 Cylinders. If one had been several pounds lower, that would have indicated problems with rings or valves, etc.
