Hi All I'm new here and it

Hi All I'm new here and it sounds like you all know your stuff.
Any how I have a 1977 470 w/ I think is an alpha 1 ( square top with lift ring) Had to replace the water pump and now the lower unit won't slide on all the way. it gets to about 1/2 " and then feels like it hits something. Must I have it in foward and how do I tell if the lower unit is in forward?
 
To put the drive in forward yo

To put the drive in forward you would turn the little shift shaft clockwise till the prop locks counter-clockwise ( and will rachet clock-wise )

So the drive will not go all the way if the shift shaft isn't lined up or the water pump tube isn't lined up.

its a little easier to do with it in forward but not necessary.
