Lowers are the same on regular Bravo and X drives.

Thanks guys,I will inspect the 1,50 before I use it,its for a 27 Rib with a EFI 500,I dont like the idea of using the 1,36 and go down on pitc on the prop,I did use a 1,50 with a 26P Bravo prop last year and it was Ok,this drive is worn out,and I got a x drive 1,36 and a spear 1,50 lower to use.

there are a couple places on web to check gear ratios, but i am pretty sure 1.36 and 1.5 take same upper gears. some of higher ratio drives use diff upper gear tooth counts.

The ratio is controlled by the upper gear set in Bravo 1's X's and XZ's. The lower gear sets are the same.

XR's use the same upper gear set and use the lower to control ratios.

Ok,so now we are sure the gear difference are in the upper gear,so its no use to change the lower.

What pitch to use with my 1,36 drive when I used a 26 Bravo with my 1,50 drive ? Can I make it with a 24 P ?

Thanks.
