Over the weekend I noticed something that I have never really paid attention to before. I have a 2018 Craz with the Raptor 400 in it. The normal operating temp when cruising around 25 mph, surfing, wakeboarding etc. Seems to be just above 160. However, we were on a larger lake and cruising around 35 mph (probably around 5000 rpm) for a few minutes. The temp got up to 179. As I backed down in speed, the temp would drop to mid 170's, but never back into the 160's until I got down to around 25 mph. Is that normal? I thought that seemed pretty hot. I replace the impeller every year, so it only has about 40 hrs on it. I am going to check anti-freeze to make sure it isn't low, but it was at the low line "cold" before we left for the trip. Just curious if everyone else sees that higher temp at higher speeds.
