Hello, so my head gasket repair on my 85 merc 3.0 was successful, no more water in the engine, good compression etc. now I’m battling this shift interrupter problem. At first the engine would die going into gear if the cable adjustment wasn’t right and die every time shifting into neutral so I replaced my lower shift cable. Only replaced the inner core due to not having the special tool. Now the unit shifts into gear without dying ever but will still die going back to neutral when in the water under load. I think that the problem is related to either A - excessive play in my upper shift/control cable, or B- wear in my HI-LEX POS control. I think that because the interrupter will not kill the engine when I shift real quickly back into neutral and give the throttle a jiggle once in neutral. There has always been some play in neutral where I frequently have to move the control a little I think usually coward sighing leaving neutral just on the front end of the play it has to start the boat because otherwise the neutral saftey switch won’t allow the ignition to work. So back to the interrupter when I shift quickly back to neutral after being in gear if I don’t find that same area within the play quickly the engine will die...could the interrupter interact with the neutral saftey switch? Controls are expensive so I have begin putting that off. Do you think a worn control cable could be causing this? I don’t think it is an issue related to keeping the lower shift cable jacket in place since the issue with dying going into gear has been resolved. I think it has to do with this play in neutral? Any suggestions or tips?
