The temp stays at about 175 degrees but rose a bit when I picked up the revs. I really think it is an instrument problems so I am going to start there by cleaning all the terminals at both ends and then moving to the sensors. I will probably change out the coolant as well as I have no idea how old it is. In the meantime I had the frame for my new dodger built and I installed it so I could learn all the things not to do when drilling holes in gelcoat. And of course there was a lot of dropping tool and stuff over the side......but that is another story.

LOL.
I am a project engineer who works in heavy industry, chemical plants, paper mills etc.
I always tell the young engineers for check the instruments first.
