I have a 1996 24...it has a 502 magnum with closed cooling. The motor used to run at 165 degrees..lately going up to 180 degrees. I changed the thermostat and the raw water pump and had no change in temp. Does anybody know the normal operating temperature for this engine???

I would bet there is some build up on the sending unit giving you the different reading.
If it's not the sending unit, then maybe the heat exchanger is plugged up some.

Flush the heat exchanger... 99% of the time its a plug in there somewhere. As Pat said 180 is still in the green but a 15 degree jump is a little unusual.
