I have a lead on buying a used Imco set back box. This one is not the standard type of extention box this one is like the Land and Sea Sternjack. Yes ,Imco manufactured this several years ago. I would really like to purchase this because unlike the Sternjack the Imco unit has provisions to use my existing hydralic steering. The problem is the Imco unit is set up for a standard Bravo 1 u-joint, well I run a XR drive which has bigger u-joints that don't work with the Imco unit. What I need is a combination u-joint that has both the standard Bravo size and the XR size. I have called locally and haven't been able to find anything.

The sizes of the u-joints are:

Bravo 1 Merc part #75832T1
cap diameter 1.078" cap to cap 3.232"

XR Merc part #862132T
cap diameter 1.329" cap to cap 3.447"

both have internal clips. Any suggestions would be helpful.

Yes ,
I've tried several driveline specialists, and Imco. So far nothing. It seems that there is too big of a size difference. I guess the XR u-joint is larger than what they use on a 1 ton truck. Seems overkill to me.
I'm going to try one more place tommorrow , It's called Billet Marine and they specialize in Bravo/XR conversions.

Imco stoped making them because they had problems with them ,they seem to preload the gimble housing . I would look int getting a regular stand off box that mounts to the transom.
