Unusual Over Heating Problem on Opti

I have a 2000 135 optimax 90 hrs, engine is super, but has an unusual overheat problem, which does not show up on the computer read out. After running across the bay and then to idle,and also at troll speeds of 15oo to 1800, the temp will shoot up to 165 and above on the smart gauges, and will when trying to get up on plane abain put motor in slow mode, idle around until temp drops, and no problem. I have a new water pump,and flush with salt away, just change the thermostats, which probably did not need to be replaced. I have heard there is a restrictor some where in the system and a screen/filter below the powerhead that may cause the problem. Any one have or had any info or a similar problem.

The most important sentence in your post is mangled. Sounds like you need to replace the sensor that is used to put it in slow mode. 165 degrees is far from overheating.

I see my problem in writing cannot believe I would do that.
I know 165 is not an extreme temp but I think 165 is the point where opti engines go in to slow mode. I will check manual again for this. I have had it my friends in the Merc service center and they found nothing wrong, and the computer shows nothing. I do believe it is a sensor problem some where.
