Not at all Bro. None of the gauges I've had on there are considered "waterproof" but they all did fine in the rain. These may or may not be alright but I could seal them up pretty easy if I needed to.
This temp gauge will read 1 degree at a time.
I realize that, but I recall a photo of your original analog guage reading about 210 at five bars and the new one is showing 197.
