Enertia Prop Hub Kit

[MPII]

Hello - I just purchased a Stainless Enertia Series Mercruiser Prop, 19 Pitch. I have an Alpha One, Gen II outdrive. The prop came without a hub. Does anyone know which Hub Kit I need to get for it?

I believe it is the MerCruiser / Mercury Prop Hub Kit Flo Torq 2 835257Q1. It has a somewhat squareish cylinder and from the photos this kit looks to be the same.
