With navigation electronics on, the water temp will climb and max out on the gauge, max indicated 220deg F. Which occurs with 2 VHF, 2 small MFD, 18" radar, auto pilot on. If I power off electronic items the water temp gauge will drop to approx 190deg, which is 10-15 deg above actual. The oil pressure gauge has the same issue, but indicates very low pressure.
Actual engine temp is normal, monitored with heat gun. Water coolant tank temp is approx 175 deg.
What is happening and what can I do to remedy?

Thanks in advance
