I recently purchase the speed controller to control my trolling motor. I’m very satisfied with it except the speed dial won’t stay in high speed when you let go of it with your fingers. I have to keep constant pressure on the speed dial for the motor to run at the highest speed. Not good, is there any way you could send me a new speed dial (pot) or give me a good part number so I can replace it, maybe ASAP. Fishing is good right now in South Texas!
