In my world that prop still has plenty of life in it but in my world its life span would only be a couple more days because whatever caused that ding would end up eating it in short order. If you can feel the vibration when you are under power or if you notice a drastic drop in top speed then get it fixed otherwise use it until the end of the season or until you do a better job of eating it up. BK has a picture somewhere of a prop of mine that has one day of use on it. By the way—you can get that one rebuilt much cheaper than getting a new one. Believe me I know—I get them rebuilt two or three at a time.
