You will need to measure your plate from top to bottom for correct fit. If your plastic plate has a ridge or lip on it, measure between the top and bottom lips. If your plate is the newer model and does NOT have a ridge or lip, then measure the whole plate from top to bottom.
If you have a question concerning the graphs you want to mount, call the shop and ask - 706-217-6161
Each Triple mount comes with a replacement bow plate. We have also integrated a slider bar system for the Top and Bottom row to be able to slide the units to the left and right to help miss whatever brand trolling motor you have.
