Beneteau 393 BOHM
I have a 2005 Beneteau 393 and cannot read what this is. I was out today and the red light came on and I’m not sure what it is.
The 1st pic is the gauge. In question it is the 2nd gauge on the left on the 2nd pic.

The gauge you show is the water temp gauge as the scale is not linear. Oil gauges are linear. Here's mine shown below :

If you've got a red light as well, you've got your work cut out for you.
