type of boat
My boat is a Merit 25... balsa cored.
So you think it's better to install a thru hull transducer to avoid a possible mess with the core? To me is somehow the same, I mean, with a thur hull you make a hole in the boat, with a shoot thru, you only digg from the inside to the outer layer.
I was thinking to epoxy the transducer and then fill the gaps with polyester resin to make sure there are no ways into the balsa.
Perhaps it would be easier to try the transom mount and find a spot where the thing gets wet always (underwater)
