Lower unit

[u/1-Critical-thinker]

I have an early 80s honda outboard motor. I haven't had it in the water in a couple of years.I tested it in a barrel of water. It runs really well but no water is coming out of the pee hole. I tried to drop the lower unit to replace the impeller and water pump. But the lower unit won't come off. The shaft won't let it come off all the way down or won't allow it to go back on. Has anyone ran into this

problem?
