I'm considering placing either the B175M or the Bl75HW on the starboard side of my 2320 as my Simrad transom mount is quite limited - was wondering what what degree tilt i should be using.
You are probably going to get a lot of different answers here on what others have done. I have a 2320 (2014) and installed one last Spring B175hw on bottom of Keel (Skeg) flat area about 12-16” from end of transom. I will attach pictures it is a 0 degree and have really been impressed with it. Completely clean screen no feedback. Reading clear at all speeds. I did have to take a small notch out of my battery tray to make the install.
