The needle position can be adjusted. There is/are a slot/s in the back of the temp gauge to adjust the needle position.
(I can't remember if there are one or two adjustment slots in the back)
The 6 dots on the gauge face, 2 under each of the C,N and H correspond to specific water temps but I don't know what they are.
My S has the needle slightly below the N when the thermostat - 180 deg F, starts to open.
The needle centreline is above the LH edge of the N. It has been this way since new.
Are you sure you have the correct sender?
There are a multitude of different senders out there, some genuine Smiths and some aftermarket.
Hope this helps

I bought the sender that John at MKO recommends. My old sender was doing the same thing. This is the one I bought.
https://minikingdomonline.com.au/produc ... -cooper-s/ Both old and new are the same sender marked B710.
As they sit now the one on the engine is 660 ohms @18 deg. The old one is 850 ohms @ 17 deg. To do a proper comparison i will have to take out the new one then compare the 2 using hot / boiling water.
I think i will try the adjustments on the gauge first.
That's interesting. My temp sender has the red centre too, but a few people have told me it's the wrong sender, should be black, but it works fine. Maybe the color means nothing and varies with brand. I think when I tested mine with hot water the beginning of the red was exactly 100deg. Somewhere on here there's a bulletin/post saying what temps should be on gauge.
