bravo,bravox,bravoxr?
 

i've got 89 bravo's and gimbal housings. i'm probably looking at replacing at least one drive b4 this season. i've found bravo 1 for $4000 including prop, bravo x for $4750, and bravo xr for around $7500. what is the difference between the x and xr and will either bolt up to the bravo 1 gimbal from 1989? thank you for the help, eric

I beleive you will have to change out the gimbal bearing with any of the new X or XR drives.
