I read a thread somewhere on here, but can't find it for the life of me. I specifically remember someone posting that they are looking for a 3-bladed prop for a 20-hp merc. I HAVE ONE and WOULD BE WILLING TO PART WITH IT. I just have to find out if it will work or not. Please respond and we can figure this out.
