What does this symbol mean?

Hi, new to the forum. We are having problems with our mercruiser 5.7. Trying to diagnose what may be causing our boat to go into guardian mode. Engine temp is fine. Oil pressure looks fine. This reading seems to be stuck at 40.5. Thinking we may have a bad water sensor.

Hey TIC. Welcome to the Cobaltchat forum. So glad you found us!

Are you sure that’s not the hours on the boat or the top speed reached in that display?

Your dealer can hook up to the ECU and read why it’s going into guardian mode.

Keep us apprised.

Again welcome aboard mate!

Thanks for the welcome. There is another display that shows hours. Not sure about top speed. We are trying to diagnose before pulling it off the lift and out of the water to take to the dealer.
