The shaft is splined. Make sure all bolts have been removed. There is one under the trim tab on the housing. It is possible that the shaft has a little corrosion. Be careful and check. If all bolts have been removed, try pushing the lower unit back up and then pull down. This will get a little more movement.
Good Luck and have Fun on the Water "
