I know all the bow lifters are higher rake props. I believe Low rake props provide more sternlift . . .
Tim is right on here.

High continuous rake props provide lots of bow lift. Low continuous rake and Progressive rakes props tend to provide more stern lift. Generally speaking, 4 blades also provide much more sternlift than 3 blades.
In general, one of the rules is that the greater the proportion of forward thrust created near the point of rotation, which is the hub of the prop, the greater the stern lift.

Of course there are a great many other factors which affect all of this, which is why there is no substitute for putting a prop on and giving it a try. The experiences of so many members here on CSC who have tried so many different props is a great resource.
