Just bought a new TI2 12 inch and looking to install this weekend. Looking and researching I've found a lot of guys running their transducers under the Motor transom having them bolted to the hull pad where the bilge drain is located also seen guys just mount it regularly directly off the back of the transom but nobody ever says if it was a correct location or how it turned out. Anybody can give me some in-site into this. Pic of my transom and areas in question included w post. Thanks.
