When I was on the lake yesterday I got shocked when I touch the throttle box and the box only. I know its a short, but can anyone tell me where. I have a busy week and need the boat for a big weekend. So I don't have the time to chase wires. It only did every once in a while and I have own this boat and motor for three seasons and has never done this.

It is likely a wire that has lost its insulation, inside the MerControl. It should be the white or red, since they are the ones with power when the motor is running.
