I just converted a Framed Minnesota LTD. I have a post on it here on this forum. Looks like the Marquette is a very similar frame. Only issue I had was that I had to cut off one cable guide on the bottom of the downtube to get the BBSHD to snug up to the frame. That probably voided the warranty, but so does putting a motor on. Either way, a simple hacksaw was all I needed. This is my second Framed bike and you do get a lot for the price.
