Guys,
I would like to install some type of water gauge on my boat, but I'm not sure which one. I thought water presure would be the most informative, however, based on the most common gauge sales, water temp seems to be popular.
1) Which gauge is most useful, and more important?
2) What temperature should I be looking for on my GT?
3) What water presures should I see on my GT both at idle and WOT?
Thanks all!!!!
