This was in bilge near pump.

Could it possibly be a high water sensor? Johnson controls makes one like that that is flat and about 2cm x 5cm. Any markings or approximate size? What's the wire go to?

 

[Ingram]

look like it goes forward maybe foot or so, in front of the bilge pump. Their a round pod at the end of the wire, maybe old depth finder transducer?

Doubt transducer. Can you trace the wire back all the way. Never saw anything like that

... maybe old depth finder transducer?

Even new transducers are quite a bit larger and thicker than that.
You have two user names: @Ingram and @ingramsail ?

The wire leads to a round black pod 1/12 to 2 inches wide and 2" tall. It's out of my reach and glued to the bottom.

That does not help me

One side of that object has countersunk mounting holes for flat head screws. The other side has a fuzzy or brush like surface that covers the entire bottom and the mounting holes. The top side with the screw holes visible has what appears to be two electrical contacts. My guess is that the bottom is velcro or some similar means of attachment to the bilge bottom instead of the screws. The top probably had some kind of snap on device maybe for batteries. Send photo of other end if possible. Love puzzles.

I'll try too get a photo of it week.

Was the prior owner a rower? It's a mounting bracket for the Nielsen Kellerman rowing display called the Speed Coach (nksports.com). I'd guess the PO was mounting the NK impeller under his boat to use as a speedometer?

I once had the display unit stolen out of my car by some thief who probably thought he had a pager.
