I swapped to a 52″ minn kota from a motorguide. The holes do not line up. There are 2 sets of holes in a minn kota, one is for mounting, and are reinforced holes, and the other are not nearly as sturdy looking. I drilled 5 new holes, reinstalled with aluminum plates that came with the motor guide, and fabricated 1 new plate. The mk needs 6 bolts, mg only 4. I also use a short arm ram mount to hold the motor down securley when travelling in rough water. It keeps it from bouncing up and down.
