I am in the process of replacing the shift rod on a Johnson QD 19 and was about to put the skeg back on when I realized that I don't remember or didn't notice the orientation of the tab on the inside end of the gearcase head/bearing assembly. Neither the skeg nor the lower unit housing itself seem to have an indent for it to lock into. Anybody have any ideas as to whether the little tab should be pointed up, down, or to either side? Does it even matter?
