I have a 1979 OMC 140 IO in a Larson runabout. When adjusted

Customer Question

I have a 1979 OMC 140 IO in a Larson runabout. When adjusted correctly, it will start in neutral, engage in forward and run perfectly, including going back to neutral and re-engaging in forward. However, when reverse is selected, it works correctly and goes back to neutral. From that point on it will not start until all the cables are rearranged manually. I suspect the switch on the engine control cables??

Hi, my name is ***** ***** safety switch is in the control and is closed by a cam inside the control when the lever is in neutral.It doesn't sound like a bad switch to me, it works every time when coming out of forwards but stays open coming out of reverse.It think the cables are either maladjusted or there is one or more worn cables.You could test the switch with an ohmmeter if you wanted to.I suspect the rear cable from the engine to the drive.Do you need to overshoot neutral with the lever to get it out of reverse?
