You need to start by removing your prop and looking for size (diameter), pitch, or a manufacturer and part number stamped somewhere inside the barrel. Prop could likely be re-hubbed and blade repaired by a good prop shop for considerably less than replacement cost or you could replace with a comparable aluminum prop for not too much once you know what to look for. You'll need a standard rotation prop, reverse rotation is only for one of a pair of twin engine setups.

Without a starting point, one can only guess at what you need so that starting point is the prop you have now. Look for numbers such as 12-1/4 x 13 (12-1/4 inches in diameter and 13 inches of pitch). I'm guessing, but I feel thats what you currently have and will be close to what you need.
