Hi all,

The boat has previously had a transducer on the transom and I would rather not drill new holes. I have attached a photo of the penetration thru the hull and am hoping that someone will recognise the cable cover or hull penetration that would screw into the three holes that are already there. As I may leave the transducer there (semi-) permanently, I aim to fit it right the first time.

Maybe this? https://www.roadtechmarine.com.au/ve...-40mm/p/MHI015
