2) Temperature gauge or sensor may be wrong ... once again, if she is stable, then fine... can you swap the cables on the instruments around to check the insrument? ... if same, it could be the sensor .... but once again is she stable after 15 min + ?
What is your max RPM .... oh ... and are your RPM gauges correct, or do you have an un-even load on the engines ?
Is one engine heating water as well as cooling the engine ? ... if so, you will have difference in temp as the one heating the water have more liquid circulating, thus more cooling capacity and thus cooler liquid....
When we run at 1800 RPM (Max 2300), we run at about 87 deg C on port engine and about 93 deg C on Stb ...(Port engine is heating water).... at WOT we rise to just about 90 and 95 respective ... on the gauges that is.... but we have mechanical gauges near the engines, and they show 3 - 5 degrees less.... but all are stable once temp is reached..

I've stopped drinking water .... I have seen what it does to the bottom of our boat!
