I have an 89 150 and was looking to install a temperature gauge. The engine has the stock sender, what modestly priced gauge and supplier would yall recommend? My other question was what is a good way to test the overheat sensor? I had the misfortune to find some muddy bottom shallow water with the LWP and I know it got hot but no alarm. I get the beeps when I turn the key. After a lot of work and headaches the engine's been running great, special thanks to w2f a vking for the timing advice. It hasnt missed a lick since :D
