Just put a new Mercruiser 260 in my Cobalt. newer inner plate and gimbal ring the entire works. I've got the front mounts about as far up as I can go and the alignment tool goes in with a little bit of a push and when I pull it out on the end of the tool I see good even spline marks in the grease all the way around for about a inch down then the spline marks are heavy on the bottom and bare on the top of the tool. I cant seem to figure out wich way to go here now.
