I purchased a used 2001 MInn Kota Maxxum bow mount 74 pound thrust trolling motor for my 1990 Astro 18FDX bass boat. I used the trolling motor ove the weekend and noticed that the speed control does not seem to be working properly. It goes from slow speed, about half way between off and 10, to full speed between at about a 20 setting. I am looking for parts to fix this problem but I am having trouble finding what Im looking for. Does anyone on here know how to go about getting the part to fix the speed control. the part looks like a typical potentiometer from radio shack but there is nothing like that in the exlpoded view that I can see. Any ideas???
