temp gauge Or sensor? took the Boat out tonight & my temp gauge kept fluctuating between 160 (normal ) 110 , would this be the gauge or the sensor ? Were is the sensor located on a 87 ford 351? Any info would be greatly appreciated. I Figure it is probably a loose wire!

would it be possible that it is your thermostat?

Usually, if the temperature fluctuates that way, it's because the impeller isn't pushing enough water or there is a blockage in the cooling system. Most of the time, when a tharmostat goes bad, it's stay open or have a hard time opening. If the gauge doesn't jerk from high to low and the changes are smooth, it's not the gauge.

Opened the T-Stat & examined the thermostat , It had small pieces of rust preventing it from closing.

Thanks so much!
