Has anyone else done this? I have been unable to knock the old one out through the hole in the hull and am nervous of applying too much force. Should I just drill it out and hack it into little bits? Or is there a scientific method? I have a like-for-like replacement which should fit the hole!
And I have a new Garmin "fish finder" set in resin as well which is a much better system, but I want my old Stowe system fully functioning!!
Thanks in anticipation
