I have a 175 Evinrude FICHT model #E175FSXEL serial # 4439333. I launched the boat last Wednesday and when idling the tempature was at 140 degrees. By the time I got to the end of the channel the gauge read close to 200. I increased the throttle alittle to around 2000 rpm,s and the tempature gauge went to 175 degrees. When I returned to the marina while idling the temputure went to 200 degrees again.

Is this normal for this motor? Last October I installed a new waterpump and the water is pumping good. The motor has 160 hours on it, pinned heads, new oil pump and software upgrade #5001212. Any help would be appreciated. Chris
