    What's this thing in my bilge?

    What is this little puck in my bilge?
    There are two of them in the forward section of the bilge. same spot on both sides. Looks like a #10 screw coming out of it.
    There is no marking or any indactor in this area on the outside of the boat.
    What is it?

    Re: What's this thing in my bilge?

    it looks like some one left a grinding disk and covered it with resin

    not sure what the heck that is. I had to go check my excalibur to see if I had that there but I dont . its hard to say what previous owners had done to boats. I know I found a few odd things in the bilge.

    good luck

    Is it possible it's part of "Bonding System"?

    maybe a thru-hull transducer for a depth gauge? then again i don't know why there would be two.

    Looks like it was for mounting something else, rather than looking like some kind of transducer.

    I have never seen a transducer that looked like that.

    I have two... one is for the digital depth gauge in the dash and one is for the sounder.

    But one of mine hangs off of the transom.

    Might be a mounting plate for transducer with hole drilled and then sealed at factory for optional electronics package install.

    Could be a plug for a water intake port.

    Re: What's this thing in my bilge?

    They have been in there since the boat left the factory. The factory gray bilge paint was covering them when I got the boat.

    I'm looking for a place to install a shoot thru transducer so I'll need to remove coring to do that. I was kinda hoping I could just cut one of these out to do it.

    I was hoping somebody might have seen these before.
    Thanks!
