Hi I have a little trolling motor that is doing something strange. The motor will not shift into neutral. I took the lower apart and observed who it works.It is not you normal arrangement(clutch dog, spring and button) it is a coil spring that is on the shaft between the drive gear and pinion get the shift shaft protrudes in neutral and catches the end of the spring and does something to cause the gears to come apart into neutral. not sure what to do. Should I replace the spring or shift rod or both? Any advice will be appreciated. Any one else have this problem? Thanks....Robert
