Need help on placement of water temperature sensor!

Hi I have a 2019 Mercury 115 4 stroke . From the 4 pictures below I was wondering if you could put a old school analog water temperature sensor in one of the two plugs not being used?

Unable to find the sensor next to the plug and assuming its a water temp switch maybe, if this is the case then I would believe a analog sensor could be installed.

To verify remove plug and see if water comes out with motor running.
Don't know the serial number

Serial number 2B723092 I would like to leave setup like it is with the warning horn. I’m just trying to see if I could add a sensor in one of the two places I found thanks for your help

Looking at the parts list I'm still not finding the sender in the first 2 pics, but do think that would be where I would try.

Did you install a temp gauge sensor there?
