I just bought a 1997 Johnson 115 hp ocean runner. its a OIS ignition 60 degree looper v4. the seller took it in trade off a pontoon boat where the owner ran into a dead battery problem and was jump starting the motor often... then from what I understand he bought a new battery and connected it while the motor was running( info I was told) and he killed the motor and now it doesn't have spark.... he replaced what looks like the coils and the trigger sensor(optical eye im guessing) but still no spark.....so I don't have a control hooked up to it, but we turned it over to check compression..120 psi in all 4 holes!..thus I bought the motor. im sure I have a set of controls to hook up and Ill give it a shot at starting on my own once Ive rigged it on the stand.....but it sounds like he fried something....because the motor was running before he connected the battery...so maybe there is a common thing that's gets fried when underinformed people start troubleshooting things!! anyone know of a possibility?? from reading a lot , Im thinking the stator might be fried..ive never replaced one of those... I have many of these motors and have replaced most things...but have never removed the flywheel and then put it back on!!!!!! thanks bob
