have a solid hub bravo 1 hydromotive prop I am going to try, see nothing for a lock ring on this, do they use a lock or just a lock nut ? thanks Rob

Had the same issue. They require a spacer that has splines and locking tabs like a torq flo. CP sells them by the pair???? Amazon has singles though, about $15.

thanks...ended up cutting down one from a bravo 1 mount worked fine

Here you go for future reference.

If it is propeller hardware, we have it. If it isn't on the web site we still have it.

Thanks,
