|Prop pulling normally only is problematic with some folding props. Almost any puller will do for a 2-blade fixed prop. The C-clamp style with a screw bearing on the centre of the shaft is preferable to the type you hit with a mallet.
I'd double-check that shaft diameter (not that it's particularly relevant to this task); most 27's have a 7/8" shaft.
