Is it not pre-wired for a trolling motor? On my 1999 KW 1720, I just had to mark and drill holes for the rubber trolling motor mounts. The deck is reinforced, and you should not need a backing plate. I have the exact trolling motor on mine, and have had no issues with the rubber mounts pulling up or becoming loose. The entire process took about 30 minutes, and I took my time and measured everything 3 times.
