I have a 1996 Sea Ray with a Mercruiser MCM 5.7L. I have been troubleshooting the temperature by following this guide (https://itstillruns.com/test-water-t...t-7949115.html) because my temperature gauge is essentially stuck on ~190'F. It does not change when the engine is on before or after warm up. Key off it goes back down. Infrared readings indicate normal temperatures.
My gauge appeared to be in working condition as it pegged high and low as expected. I replaced the sender unit as the ohm readings were not in range. The new sender unit still causing the gauge to get stuck ~180'F now.
Any ideas on next steps?
