if your trying to pull the shaft and carrier by using a slide hammer attached to the prop shaft you have to remove the shift shaft first.
to pull just the carrier I use the puller legs from OMC and oxygen acetylene.
if its a left hand case the carrier and propshft come out as an assy after removing the shift shaft.

Rob, thanks for the reply. Yes we are using a slide hammer. We thought about using a little heat on the casing but was worried about warping the housing. We did remove the Shifting shaft and tried the hammer without luck. And you do think a bit of heat will help? Thanks for the help, Jereme
