Attention users of Mercury Flo-Torque "square"bushing prop's,

[popeyebob]

There is an extra bushing needed for high performance, and surface piercing application's. This added bushing is supposed to help center the prop, and reduce the chance of failure of the square hub bushing. Cost is around $20.
See attachment.

thanks for the info,will the bushing reduce vibration, my chopper has a lot more than the trophy,andhave to constantly keep tightening this prop. the flo torque 11 was shipped with my chopper 11, i have been told its best to have a hub pressed in this prop.

I didnt know the bushing exsisted till yesterday.It look's like it center's the hub better. I have hot had a chance to try it yet.
Look's like I paid $12 for it, according to my receipt. Seem's like it cant hurt !
