What parts do I need to run switch from a Bravo 1 prop to a Hydromotive? I've not been able to find clear documentation on it.

Thanks, Cole

The hub insert is shorter on the hydromotive. You can purchase just the insert with the round rubber pieces. The insert for the bravo is longer and the hydromotive prop will not tighten up if you try to use the insert out of the bravo prop. I went from bravo to P5X hydromotive.

I'm looking to mount a Quad-IV.

Got a part number?

Boom! Thank you. I still haven't been able to get them on the phone.
