Two years ago when I got my 2001 185 the system was defective. I found that it did not make that much difference to the control of the boat with or with out it this year I removed th system completely no problem. If you want to fix the issue then take off the housing and see if the magnets line up with the switch and are close enough to activate the switch also check the wireing at the switch. After I took mine out I found the wire had broken due to corrosion and that was the problem. Good Luck Shasam
