Ok , circled in yellow is the wire in question. Where/what does it connect to?

I can't find it on any of wiring diagrams anywhere lol.

Thanks

Looks to me like the thermistor-switch that closes when the engine overheats, this connect to the kill-circuit

Yup, but the problem is I need to know where it connects as I can't see/find it. That's why a picture would help immensely.

That is the thermoswitch, but I doubt it goes to the kill switch. Rather It usually goes to the overheat warning horn. The Thermoswitch wire is Tan and Green it attaches to a tan and Blue wire that goes to the #3 plug that goes to the front. Usually there is a horn either in the binnacle or under/in the dash. This switch grounds the negative side of the horn, The other side goes to the + 12 volts supply.

That is the standard wire color codes and if the horn is there or not the switch would be the same. Depending on the boat setup I would put one in where I could hear it if the motor were to overheat.

Usually a motor with electric start and charging capability's has a warning horn.
That part that's circled is called the thermoswitch.
The switch hooks into the wiring harness and then that connects to a buzzer.
Try grounding the wire/sender to the block(key on) the buzzer should sound off????
