G2 200HO over heat

Hi, I have a new G2(H200HXAHB) sn 05536460. I have put about 50hrs on her and she has run perfectly untel yesterday 10/12/19. she runs about 150degrees at idle and has run 175degrees when over 3000rpm and yesterday when i ran over 3800-4000rpm the overheat warning light on my rpm gauge came on. I slowed to idle and the temp droped down to 150degrees again so i tryed running around 4000rpm again and watched the temp climb above 175-185 on my garmin then again the warning light came on so i idled to the dock.  Any ideas?

Thanks

I have a G2 250HO and it normally runs at about 185 degrees when turning around 4000 rpm.

Thanks for the reply derelectrk, I wondered what the normal opperating temp was. Did your warning light ever come on? How many hours do you have on your motor? Mine never went into safe mode but i reacted as soon as the warning light came on.

What instrument gave the warning light?
It could have been a Garmin overheat warning which would be adjustable in the instrument.
Evinrude has both an "engine temp above range" which is warning only and an "engine temp over range" which sets a warning and S.A.F.E. mode. I'm out of town and don't have the service manual with me to check the temps at which those set. I think temp above range is over about 193F.

Thanks Rick, both the garmin and the evenrude analog tach gave warning but i didnt run it long after the warning light on the tach came on so it didnt go to safe mode. It has run fine since day 1 and i have run it to test props now turning 5700rpm wot. I had the side cover off to check and top off oil tank (.5gal xd100). I thought i read somewhere about a pinched water line? I took the boat to my dealer so they could check to see what they can find. Im sure its nothing catastophic as the temp would drop to 150degree when i ran at idle speed (500rpm).

Temporarily connect up a water pressure gauge if you do not have one and monitor the readings at idle, full throttle and evry 1000 rpm increment and compare it to the factory specsl
