Posted a question a few weeks ago, didn't get nay feedback but wanted to try again. Planning on installing an Airmar B60 through hull transducer for Lowrance on my 20' Grady. Hoping to get some feedback from anybody currently using the B60. It is a flush mount tranducer pre-tilted either 12 or 20 degrees so it flush mounts (3/16" reveal for flange). My boat is a 15-16 degree deadrise. Main thing I am worried about is if the difference between my 16 degree deadrise and the 20 degree pre-tilt 9recemmended for 16-24 degree boats) will have any noticable effect on my fish arches etc.. Any input appreciated.
