The 25 has a higher compression head than the 18/20s. If it has lived in salt water, you are lucky it has any compression at all. The cylinders usually develop separation between the aluminum and the steel liner and often will leak water into the combustion area. I bet if you get it running and recheck the compression, the numbers will be down a bit but still in the 125 range.
Long live American manufacturing!
