This is what I use on the boat for oil pressure and coolant temp. (Autometer pro lite warning system)from jegs or summit. You can buy the sensors in the pressure and temp range you want. I have it mounted in my field of vision and it shows up in bright sunlight. Plumbed in on a T with my guage sender. You don't want a boat shutting down on a pass.
