For some reason whenever I go out on my boat the next day my water pressure gauge (and only my water pressure gauge) looks like this.



Can I fix this or is the gauge bad?

I can't say for sure.. But the little resevoir spring thing inside probably has a tiny hole. I took one apart once and tried to fix it.. I always questioned it's accuracey after that so I scrapped it.

I had a problem like that and sent it back to the manufacture and they resealed it.

The seal on the guage is bad and its getting condensation inside it.
