I have a 1973 Anthony's chaparral with a Oldsmobile 455 high performance.
I just got this boat and wanted to run it on the trailer. So I hooked up the water hose to it and let the water come out the exhaust before I fired it up. I let it run maybe 5 minutes then it started to die. I looked at the temp gauge and it read 240*. I called the previous owner and asked him what temp it ran and he said under 160# in the lake. He said it will get hot running it on the trailer even running the water hose. Is some thing wrong. Shouldn't it run with out getting hot like it did with the water hose?
