can it be wired to an alarm buzzer on a boat?

This does not have an alarm prior to shutdown. image.png

Will this work on an older Mercedes marine diesel engine, 1970s?

works with any engine that has a port for 1/2" pipe thread, Mercedes were metric, you would need to make your port threads to 1/2" NPT. Also, To work this gauge right you need a tattletale relay to shut engine off when temp gets to high.

Which one has the single wire terminal post to activate the shutdown? That is the one I need.

They're all the single wire. The last few digits are the length of the capillary tube. Its a 20t series (gauge mounting size 2"), 250 degrees max and the rest of the numbers are the length (6ft) and pipe thread size (1/2).

You can use on virtually any DC voltage. It just grounds 1 wire when tripped. It must be used in connection with a Murphy switch or you could wire through a relay using the n.c. side for normal operation and this will ground and open the circut.

GAUGE EXACTLY AS DESCRIBED

This item was exactly as described and was "plug and play" to replace the same gauge on a Kubota generator on which the original supplied gauge capillary tube was too short to reach the new remote gauge panel - We have a couple of hundred hours on the new gauge now and it is working perfectly!
