Yamaha - Shift Rod Link Lower Unit Control Component 6L2-44124-00-00. Overview. Shifting problems don't always come from inside the gearcase-sometimes it's the linkage that's worn or out of spec. This shift rod link is what transfers your input down to the lower unit, so when it's loose or worn, you feel it right away. I've seen motors that wouldn't fully engage gear just because of this piece. Replace it, and the whole system tightens up and shifts the way it should.. Key Features.
