I have seen similar items on the board and have tried the fixes but has not worked yet. The engine starts and runs great however I have no neutral or reverse. There is power going through the leads to the lower unit correctly when in neutral and reverse and the wires are showing about 6 ohms through the casing. I have put mineral spirits into the lower unit and spun it and let it set and spun it again and then flushed it again with the mineral spirits then refilled with Mercury Premium Gear Lube. I was told this is what to use at a local dealer. I was not able to find OMC Premium in the local area. Is the Mercury Premium the problem? If not, any suggestions? Also, shifting the throttle to reverse works like a kill switch.
