Any idea what this temp sensor looking little guy is here in my photo? Our boat doesn't have a temp gauge and we think the high temp sensors are the two at the top of each head.

Knock sensor on the right and thermosensor on the left.
Most every part used on your motor is in the applicable parts catalog.

What is the thermos sir as compared to the high temp sensors. Is it feeding the CDI specific temp info? Is it used for temp gauges?

dude
buy a clue here shortly.
your motor has two overtemp SWITCHES.
one COOLENT temp SENSOR.
one KNOCK sensor.
its a basic stupid motor.
always look at is it a switch, on or off, or a sensor.
