are they fixable at all?

Yes it is a piece of cake. Replace the temperature gauge.

Depending upon the gauge it will cost you $25-$50.

I think you are right, it is the gauge. Some day I will replace it. But
the electrical system in my boat is such a mess that I don't want to
even touch the box now that I am not prepared to spend few days to
re-route everything that can fall off when I push that bunch of wires
out of the way to see the back of the gauge

Hate these computers, they do what they want... that was me.
