When you see the water flowing, put the cap back on and check where the temp gauge is at. That should be your normal operating temp. It should be around 180F according to the manual. It shouldn't get much above that even sitting still. Of course lack of flow during low rpm idling time does raise it up a bit.
Mine does the same thing. Winter/Summer/Summer towing the boat/sitting/moving -- it doesn't matter, once up to temp it stays right where it is in the photo, no real movement.Greybrick wrote:When this engine gets to operating temperature it's at about what the gauge photo shows and stays there without moving.
