I have a johnson v4 115 "93" bought new in "97" from omc dealer. I'm very maintenance conscience and service it myself. it runs great, turns 5400 rpm's with 19" prop and has maybe 150 hrs. a friend of mine had a compression meter and i tried it, facing rear of the motor the two left cylinders hit 125 respectively however, the two right cylinders hit 120 (top) and 100 (bottom). this REALLY concerns me for the fact of the variation of more than 15. why is that bottom cylinder so LOW?? I can't believe it's already starting to die!! please someone advise. Exaust hole on good side has good bit of oil residue after running however, weak side has no oil residue. please advise.......HELP
