No need to change prop "unless" it's a different ratio

All XR's have the same upper gear set, the lower is what changes
The others have different gear sets for upper and lower

Ok, really don't want to spend the money on a new drive. But I found a place that has new Bravo 1 drives. New style and old style. Any difference? One better than the other? Still holding out to find a good used one. But the season is moving on by.

Ok, update. I finally did find a nice clean used drive. I'm back on the water!
