Yes, the spinner on the Quest 90 in the picture is a smaller size at 2 1/2 inches and has two screw holes. I use 3 1/4 inch diameter spinners on my OS 1.60 2-strokes and they have 4 screw holes. I have had absolutely no problems with any of them.

If you feel uncomfortable about widening the cutouts in the spinner cone to fit the prop you might want to look for a different spinner. I use a Black&Decker rotary tool to bench the spinner cone cutouts.
