I have a 2021 Tracker 190 TXW with a stock Lowrance Hook Reveal 5". It uses a VESA 75 hole pattern. I am replacing it with a Helix 9 SI G4N. I did not want to drill new holes. I'm planning on using two of the Ram VESA 75 D size ball mount. One on top and one as a backer plate underneath. Then a short or medium extention to the Helix mount. I also custom ordered a spacer to mount underneath the VESA 75 mount for the wires so as to have a clean look. I'll post finished pictures of the install next month.
What do you guys think of this plan?
