Merc 120 comp ratio?

[kurb]

Looking at picking up an older boat to do some winter salmon fishing in.<br />Compression ratios: #1 110, #2 110, #3 115, #4 115. Spark plugs are a little dark but, not fouled. Engine runs smooth in driveway. Are the ratios too low? thanks, pk.

Not too low but gettin' there....It still has a little life left esp. with readings that close together....Welcome to iboats, BTW ...JK
