Well #1 pull that off and mount a transducer mounting board (Cabela's has) of UHMW ”Starboard" plastic so you're not hammering all sorts of holes in the hull. #2 it's too low. If you're willing to get some thin aluminum you can fab a "forked" plate that tucks behind the transom and XDCR. It's like a "roof" over the place where the rooster tail sprays up. Not attractive but effective. Or put the XDCR mounting board on and do the installation properly, which is what I recommend doing. I used to service, install and sell these things so I've got a little experience with them. Lowrance does have a video online for the proper installation too.
