Hi there, I just picked up a used Raker prop 13.5 x 24, when I compare it to my other Raker 13.5 x 22 I notice a few differences.<br /><br />My question is with respect to 2 sets of numbers stamped on the outside of the hub. More specifically 14546 and 12271, I'm thinking this indicates perhaps some "reworking" of sorts. An obvious change is that the vent holes are approx 1/2 inch in diameter, no problem with that, probably get better hole shot.<br /><br />The prop is in excellent condition with no signs of rework or modification and has the legitimate part number stamped on the inside where it should be and "Raker" on the outside of the Hub.<br /><br />Just wondering ???, maybe the older Raker's came like that. My 13.5 x 22 is from the early 90's so maybe the 13.5 x 24 is a little older or newer<br /><br /><br />Thanks in Advance<br /><br />Bruce
