Is a stainless worth the extra money, it has an aluminum on it now? There is a lot of rocks to hit in the shallow parts.

Yes, 11P = 11 Pitch. Stainless is more durable than alum, but also costs more. Too many variables to say for certain what pitch to use. I'd try to borrow a prop from your local marina or prop shop to check before I actually bought. Stainless flexes less than alum, so an 11 stainless will give you more bite in the water presuming everything else is equal (like cup, dia, rake, etc.)
