I would try to call the manufacturer, they could probably give you a good recommendation. Just know what you plan to do, what's your RPM's (to know if you can go up or down in pitch, and to see if you have any prop slip).

Definitely Stainless over aluminum.
The dealer should have some recommendations on blade pitch. I can't imagine a 5 blade prop on a boat that size.
Also, if there are underwater obstructions to worry about I'd got composite or "breakaway" before aluminum.
