I am lookin got buy a 20 ft DC with a 115 Johnson OB.<br />The compression is 125 on cycl's 1&3 and 115 on Cyl's 2&4. Is this something to be concerned about? It is a 1994 Johnson. <br /><br />Thanks for all the help!

Thanks Byrd.<br />Not evena big deal with the 10 difference? I thought i read somewhere that a 10+ difference was a concern??? I will be verifying those #'s with my own two eyes before buying that's for sure.

Hey crab what is important is that each bank has the same compression. If #1 is 125 and #3 has 115 your still ok but its not as good as the cylinder banks being the same. Ddbyrd is right on
