I am open for all suggestions. I will give a brief layout of my motor troubles. I took it to a mechanic for a water leak between the power head and the lower unit. The next time I took it fishing I went up river and it ran great. We fished until dark and it never started again. I replaced the CI box, disabled the saftey switch and disconnected the big red plug and tried to start from the sileniod. No luck. The only fuse that I found is fine and I believe I checked my stater Brown and Brown /Yellowwire. The volts only displayed after I stopped cranking and then it showed between 500 and 300 briefly. I tested all coils and there resistance is similar. new plugs and wires just for precausion. I have a three prong plug that goes to nothing and one solid brown wire that goes nowhere. It acts like a saftey switch but I am at a loss. The only other piece of the puzzle is that I had the oil injection system disabled due to the lake of trust I have in the injection technology. As I said any assistance will be great. Thanks
