Here is a picture of my Lowrance structure scan transducer mounted to a SternMate. I used the SternMate because it did not require you to scuff the gel coat to install the base plate. I installed this on a 2014 WX1900. There are many options for movement and getting your transducer right where you need it. I have also noticed that like the SternMate website says it will eliminate the rooster tail from your transducer it has done that. They are a bit spendy but I also did not want to drill any more hole in my new boat and this seems to work pretty well.
