I was using my riptide st 24v from 2011 when it became unable to change speeds, I did some research and determined the control board to be bad. When I found the part number, I determined minn kota has discontinued the board and there is no alternative. Would the 2017 riptide st board possibly work? The lights seem different but the other connectors are the same. I just bought this motor used 2 months ago and would really like it to not be money wasted.
