I need help... I have a 98 Nitro 700lx, I am looking for a new prop. I found two different numbers stamped on the prop... 48 77350 A15 23P was on the side, and 48 77350-C1-23 is where the retaining nut goes. These are the only two numbers I have found, and I can't find anything like this on the web.. Any ideas??
