building my first airboat

If you get the 52" 3 blade prop from Competition aircraft you will be fine. Get the 18 degree shims with it.

The hub from Arrow props does have both the bolt patterns, the Rotax and the3.5". The Ultra prop from Competition aircraft will use the Rotax pattern. The way it works, is for the Rotax pattern they are threaded holes to attach the prop. If you decide to go to a Arrow prop or 3.5 in (?? not sure of the number), you take the bolts out and attach the prop using nuts and bolts to the main hub and use the other part as a front plate.

Thanks for clearing that up Papee. The guy at Arrow had me confused. I will call today and order the hub.
