I am trying to find info on the location of the water gauge sending unit and access so I can replace it.
It appears Mainship is no longer in business to give me this information and since I have a friend with the same problem it is not uncommon and someone may have info.
Thanks for any info.
Is this a sending unit on the engine (temperature) or for the potable water supply?
If the engine, it's probably on the head or one of the heads. If you're talking about the potable water supply, look for something mounted on one of the water tanks with wires connected to it.
