What Mark said.....
I have flown my -6, 0-360 for 1100TT and my hangar mate has flown his -6, 0-360 with one for 450TT. We like the prop. Good value, especially in the used market.
One thing to watch when buying used props is history. If I am not mistaken a prop shop can straighten a blade and yellow tag it without disclosing any history. Also, if I am not mistaken a certified overhaul includes stripping the blades and re-milling them, then fresh paint. This process can only be done 3 times in the life of the blade. So it is best, if there is no damage to the blades that just an inspection and re-seal be done. Not everyone knows this information and the prop shops love overhauling them. And of course overhauling could be best as it allows a more through inspection, etc. Pretty sure an overhaul is about 2K and a reseal is about 800.
Not knowing the history, the 4500 is in the ballpark as a new BA prop is 7775 from Vans with no discount, shipping or spinner. The newer BA prop is said to be about 2knots faster.
Full disclosure: My hangar mate just purchased a new WW 74HRT at SNF. He will be selling his HC-C2YK-1BF, F666A-4 and shipping in about 7 weeks when the new WW arrives. 700hrs TT never overhauled but resealed in 2009 by H&H-Triad in NC. (KBUY). Prop comes complete with Van's spinner assembly as it is on the -6 now, painted green, with prop logs/history. He will be asking 4500.
