I need to replace a worn out Quicksilver control. I want to have seperate controls for throttle / shifting but I do not have room for a pod to mount a typical 2 handle control. If think I'll buy 2 seperate single controls, build a spacer to offset one of them so the handles don't hit each other and mount them with the pivots close together. Do I need to have detents for the shifter cable to make sure the drive stays in gear?
