So today I fake a laked my boat. All was good, but the oil pressure was zero. The gauge pod which includes gas, voltage, engine temp, and oil pressure. It seems that the gauge is actually bad. I could not short out the oil pressure sender (signal to ground) and get the oil pressure gauge to go to full. It just stayed on zero. Then I tested the pressure sender. I had 12 volts on the signal wire, and 2.2 volts with the key on. Then once the engine was running the voltage would change with the RPM's, therefore I believe the sender is working and the gauge has failed. I hope you all agree. I will take the boat out tomorrow and enjoy. Then Monday I will order a new pod gauge from whoever and also a new oil pressure sender.
