Hey guys, a while ago while installing my SI transducers, I had to fill in some old holes. I figured stay safe and just put in new stainless screws with some 4200. So far so good, but i'm resealing everything now and putting a new bracket on. I'm going to mount this one so it can kick up when it hits stuff, and a screw won't fit in the are under the bracket where the old hole that kept it from kicking up was. What is the best way to fill all of these unused holes in? Epoxy?
