I have a Minn Kota maxxum with a broken variable speed switch. I cannot get the serial number because the housing was replaced and it did not get transferred off the old housing. It is a 2002 model. I have searched the net and not having any luck. Every site i go to wants a serial number. The switch wiring runs into the module and cannot be unhooked. It doesn't look like it's replaceable so i guess I need a module. If anybody could help me it would be greatly appreciated.
