Reply To: Shift shaft ”O” ring. installation technic on OMC lower units

[jeff-register]

In the past I removed o ring , spacer & shift rod. Next I clean all mating surfaces, then lube the o ring & shift shaft & with inert lube &install shift shaft in the upper case then slide the o ring down the shift shaft until seated in the case. slide the retainer bushing down & tap into place. This way I can adjust the o ring tension with shift rod in place.
