I bought a used boat last year and it came with an extra prop. Its a 5 blade stainless steel. It's in very good shape and I am thinking of selling it but the only numbers I can find on it are 48-816612-20.<br />It fit a 90 horse merc(6 cyl). I did a search on that number but not much came up. how can I find the specs on that prop and how much it cost new new. Thanks
