My 2004 PClassic came with TE82 installed. I replaced with MaxxumPro and more recently a Fortrex and I was able to use all six bolts in the existing holes; guess I was lucky! I did have to take the side faceplate off of the Fortrex mount to access the bolt heads, but it only took me about ten minutes to swap trolling motors both times. As mentioned previously, I did cut a piece of rubber mat for a spacer between the topcap and base of the Fortrex mount. The Fortrex has been great. My only issue is that when retracted its slightly higher than previous motors and is a snug fit for my Deans cover.
