After having enough troubles in a lifetime with a standard points distributor for my 305 GM block OMC, I had the points removed and an electronic ignition system put in. OMC’s are known for their difficulty to convert. The conversion was great in terms engine performance but the electronic shift assist would not work post conversion due to the non-triggering of a reduction in RPM’s when shifting gears from drive to neutral. I had to turn off the engine coming into dock because you could not move the shifter out of gear. After doing some research on this problem with OMC I found CDI makes a ESA module to help with the problem. After the mechanic placed the module, the shifting problem was solved. Boat works great, shifts great. However, I found a new gremlin. Whenever I use an accessory that draws power ie. my downriggers or sustained raising or lowering the motor, the engine cuts out. It would appear that since the ESA module was placed, there is too much resistance to the coil and the coil is losing needed power. Does anyone have any experience with this OMC phenomenon? The mechanic working on my boat does a lot of head scratching lol. Thanks in advance.
