1. The spline top

stop (kind of) at the rear end of the groove, but further tightening of the prop nut, would chew the alu splines off at the propdriver inner...luckily no one has done this (the crankcase stops the movement before this happens)
2. The propdriver is splined right thru, i.e. the shoulder does not provide a stop.
