413 marine industrial (E) engine, to, not so industrail......

Yeah, it's got a steel crank. Hope it can be used, if not, I have another, but it's 20under.... Prob just order new one. My 318 in the boat now is RH rotation with a auto crank. It doesn't leak too bad, but the RH crank I had was broken. I do wonder if I should pitch the oil cooler, todays oils are designed to run hot, and the t-stat in these marine engines are 160f... Should I pitch it? Or maybe run the bypass through it? I just hate the idea of running 50f water through the cooler like it was set up before.
