I'm leaning toward low flow due to crap built up, but probably because I've had that this week myself.
What? Do you need some pears in your diet??

Hi there

Had the same issue , replaced a few parts as you have done , but it ended up being a bad earth on the back of the gauge .
I would check all the gauge connections .

good luck

Kevin

I had similar temp gauge issues and tracked it down to bad grounds. It was primarily the blower motor ground. My temp gauge would rise 20 degrees anytime blower motor was engaged, I ended up running a separate blower ground to the engine block. Rock steady and consistent temp readings thereafter.

Went with an abundance of cheap beers. Cleared it right up.

Here is new information which I think is not good. Skied tonight and my wife abruptly stopped the boat while in flight. The engine temp climbed to to 210. When she idled down, I noticed that very little exhaust/pressure was coming out of the port side of the engine exhaust. Other than checking for a banana in the tailpipe, I have no clue where to look. Something is plugged and I no longer think that I have a cooling system failure. Any thoughts on this twist.

Flushed the engine and installed a 160 degree thermostat yesterday. All intake houses to and from RW pump and Circ Pump are fine.

It took me a couple of days to try all of the suggestions above. This is a little embarrassing, but I found the problem: a bad temp sending unit. I'm a little ticked because I replaced the thermostat and sending unit two years ago as preventative maintenance.

I'm ready to close this out and get back to skiing. Thanks for your help.
