I think my 23 actually came with a 12" prop and not the 11" "small blade" prop. I'm wondering if I can get a little bit better load carrying with the smaller prop? my current prop is somewhat worn and has a couple of small cracks in it (i run this motor pretty hard). FTR my motor has a carb and exhaust. Currently getting around 3500-3600 rpm on the worn prop with two people and safety equipment.
