have removed my stern drive ( 1989 OMC Cobra) to grease the u-joints and it will not reinstall into the splines. The shaft will go as far as the splines, but it seems to not be alinged. I know there is an alignment shaft and a dealer said he would use this to adjust the engine on the mounts , but I don't want to bring the boat from the lake if I don't have to. Is there any method to check the alignment other than by eye and and adjusting the engine on the mounts.
