Temperature sender

Post by broompisces »

The temperature gauge for my Mercruiser 120hp is not registering at all. The needle sits at the bottom stop all the time the engine is running. When the ignition is off, or if I disconnect the wire at the end of the sender, the needle moves to the middle of the gauge. The engine has just been removed from the boat and re-installed (after some work). I'm sure the sender has been dunted in the process of removal / installation as it is the most prominent part of the engine where the mechanics struggled to get the engine out of the very tight engine bay. Can anyone advise me - could it just be a case of me replacing the sender to get the gauge to work again?
