Telling the difference between Volvo Penta 270 long hub vs short hub

[Uneducated]

As a person who in uneducated on sterndrives I have a 1977 Bayliner with an Aquamatic 270 sterndrive. I was wondering how to tell the difference between a short hub and a long hub sterndrive. Also does anyone make a quickchange hub for volvo penta to cut down on prop cost so I do not have to spend so much for a new prop and a spare. Thanks for any help.
