ya funny im starting quite the collection of johnson 70's, still going to try and make one from the three , but like trendsetter said, without boring it out it will probably run like a bag of crap, yet to be seen because we are still waiting on gaskets and rings.., funny how my buddy was all excited saying this motor was running.. what he meant was it was running 6 years ago when it sunk tied to the dock and was submerged for 2 days then sat for 6 years to seize up...kinda funny how the story gets misconstrued to guy who needs the motor..lol
