I have 2 props in near new condition. I was told at a boat shop One prop I have is a mercruiser prop but he couldnt tell me what engine it was for. It is a 48-7734-17... 13 x 17 with 15 splines. The other is a smaller 386909 12 1/2 x 13<br />with 13 splines. I would like to trade for OMC cobra 400 prop,19 pitch but need to know what they fit before placing my add. If anyone can help me I sure would appreciate it. <br />Thank You<br />Ron
