I am removing the lower shaft from an OMC Cobra 3.0L to inspect the dog clutch and gears. I have a service manual on order but wanted to get some real world feedback on this process before I started. I have the outdrive removed from the transom bracket. Looking at the lower shaft it appears I'll have to use a puller to remove the bearing housing, is that correct? Will I have to split the upper and lower to get the bottom shaft out? What else does this involve in order to pull the vertical gears up enough to slide the bottom shaft out? Any tips and tricks would be greatly appreciated!
