Mystery Part on a Yanmar 6lypa-STP

I have twin 2005 Yanmar 6LYPA-STP 370HP diesel engines. We purchased this mostly fresh water boat last year from the original owner.

On the port side of the starboard engine, directly aft of the coolant reservoir, there appears to be a sensor or unknown part.

Here is a pic of the part: http://i258.photobucket.com/albums/h...ery%20Part.jpg

There are two large gage wires and two smaller wires attaching to this part. On the starboard engine, the large gage wire that is aft is heavily corroded, as is the nut that connects this to the part.

You can see the pic here: http://i258.photobucket.com/albums/h...Close%20Up.jpg

On the port engine, the wire, nut and stud is pristine.

I will need to replace the heavy gage wire by snipping the corroded wire down to the good wire and extending it (a lead) to the part with new hardware. There is not a lot of wire to work with as it goes into a wire case and harness.

Does anyone know what this part is and what it does?

Any ideas of connecting a replacement lead to the heavy gage wire?


Thanks,

JimL
