I have a 1984 catalina 30 with an m-18 in it with the recommended 13x10 prop. after only running it for several minutes the temp goes up to and over 215 deg. I've checked the raw water pumps and hoses the heat exchanger engine water pump exhaust system replaced hoses etc. Although I have found a few things wrong along the way which I did correct I still have the hots, help!
