I have a 1982 Johnson 75 HP. I recently changed the water pump. After it was changed my temperature was running about 150 degrees. All of a sudden it has been running at about 175 degrees. The tell tale spray is working and water is coming out the back telling me it is pumping. Can someone tell me why the temperature has gone up and is there a way to flush out the system? Also, if I wanted to hook up a water pressure gauge, where on the engine does the hook up connect?
Thanks
