I have just bought a Garmin 540S GPS/Sounder. It came with a transom mount transducer. The dealer told me and the Garmin instructions confirm that the transducer can be used as a shoot through the hull mount. This is done by using epoxy to attach the transducer to the bottom but the location is important.
My question is, has anyone had good luck mounting a transducer in such a method? If not, then the second question is about how well the transducer will work mounted on the transon? I have heard for years that I/O boats have to much turbulance at the stern for a transducer to work well.
Any help would be great.
