How much vertical positioning of the prop is there? ie. how low can
a prop go?

If the upper pulley is eight inches in diameter and the lower is four
inches the mininum distance is two plus four or six inches. That is 
for a 2:1 reduction ratio. That six inch space on top of the engine
is not very useful.

I don't understand the last part of your question?
