These guys are the best. Bought an acme 541 3 blade prop from them end of last. Ran it about 3 times. Then stored the boat all winter. This year I decide I didnt like the performance of the prop on my boat and wanted a 4 blade. I knew it was way past the time for there return policy but I figured I would give them a call. They gave me credit for the 541 minus a cleanup fee and said they would sell it as a one run prop. They are shipping me a new oj force 13 x 13 4 blade. After all said and done they only charged me $80 bucks including shipping. If you ever need a prop give them a call. They also price match if you find it somewhere cheaper
