I have a prop I believe came off a 40 or 50 hp Merc. I don't have the motor anymore but I found this prop in my garage. The number on the hub is 48-73144-17. I think that makes it a 17 pitch prop and the hub has 13 splines. The prop does not look like it was run very much if any at all. It is in good shape with no dings or corrosion. A few scratches on the paint, most of which probably came from being in my garage the last few years. Give me a call at 222-7898 or email me. $50 obo - I am using the money to take my wife out to Benihana so help me out here guys:-) Location: Anchorage it's NOT ok to contact this poster with services or other commercial interests alaska
