I have finished repair work on this engine and I am giving serious thought to selling it and buying something newer. What would you estimate the value of a 1973 Mercury 20hp, stainless steel prop, in excellent mechanical condition and good physical appearance?<br /><br />I have another 1973 Merc 20 that I bought for parts (with the original engine) but have not needed it for parts so it is still intact. I don't know anything about it because I've never started it. The guy I bought it from said it had a bad lower unit.<br /><br />If I put them on EBay, what would be a fair value for each one?<br /><br />Thanks for thinking about this.
