I have a 1999 Bravo 1 drive, I have been thinking about upgrading to an XR drive. Does anyone know what year Mercruiser changed to a shorter inner gimbal bearing race, they also changed the aluminum bellows retaining ring to a narrower one making adequate clearance for the larger universal joints used in the early Bravo XR drives.

I think there is a kit to convert B1 to XR

Who makes the Bravo 1 to Bravo XR convertion kit

Mercury marine makes the kit.

Call Marc at Bam marine.

Prop inserts will also have to be purchased and changed. Simple to do though if its Merc props. The XR has a larger diameter shaft.

will the transom assembly and the gimbles take the XR? or the whole transom needs to be changed?

I am thinking about changing form Bravo 1 to ??? XR's?

Just need to change the bearing and sleeve thats in the kit from merc.

How much is the kit.

Around 100.00 or so.

I think your missing a couple of Zero's.
If not Ill take 2 lol.


When I checked into the above option it seemed like $7000.00 was the going price for parts for a pair just for the Uppers.
