    4.3 Mercruiser operating temps? Overheating?

    Hello, I have a 1990 Baja 190DSR boat with the 4.3 V6 in it. I just purchased the boat this spring and have had it out a few times this season. My question is related to the operating temp and whether or not the climbing temps I am seeing are normal? When cruising at either high or low speed...
