I have an almost new 15.5 x 17 SS Mercury Mirage Plus Bravo One prop that the original dealer mistakingly (?) installed on my boat. I have replaced it with the proper 14.5 x 17 prop for my Alpha 1 drive(at my own expense since the dealer went out of business shortly after I bought my boat)--I have never sold a prop, so I'm looking for advice on where to sell it and how much to ask for it. Thanks in advance for any help.
