I'm looking at buying this 2005 Nitro. I'm not a big fan of drilling on boat hulls and transoms if at all possible. (I know..outboard, and other bolted items from the factory which is apart of it) So the owner sends a pic of the "transducer" (attached) when I asked about it. He said it came from the factory like this. When I first saw it I thought, I've never seen a transducer like that, but thats not always saying much. To me it looks more like a temp sensor maybe for a thru-the-hull transducer? Anyway, the whole point of the picture was to see, as much as possible, what the condition of the mount/screws were in. Again, I've never been entirely comfortable with drilling into a hull/transom. I immediately start thinking of filling/glassing/gel coating. But its not easy, apparently, to find a used boat without a transom mounted transducer. But this doesnt look bad. I'm just not sure what it is, if its not a transducer. The depthfinder is a lowrance. Thanks for any feedback!
