Default Yamaha 90 gearcase, shift shaft O-ring

Pulled the gearcase off my 1997 Yamaha 90hp to sevice the water pump. When I put the gearcase on the ground I found a small O-ring lying on top off the shift shaft. Thougt that it should be in the groove beneath the splines on the shift shaft to seal off the grease on the splines.

But after looking at the spare parts list it looks like it should be right where I found it, on top of the splines. Please help me put the O-ring in the right place when I put it all together again. I have enclosed some pics showing it all.
