Looking for a prop to fit my model 40, 4hp Merc. Serial # 9148150. The numbers I was given for the prop are: 48-70453a1 or 48-86903a1.<br /> Thanks, chet
ChetJS - try over at The Marine Doctor's website. Just because it's NLA doesn't mean you can't still get it. Mercury dealers have access to a NLA parts finder that searches the inventories of other merc dealers, but some of them don't know about it.<br /><br />My brother's got the same engine pushing around his boat. But he needs the prop I think. <br /><br />The first number you give is for the old part. The second number superceeds it (plastic prop).<br /><br />PS - it doesn't look like Iboats has a prop to replace it...<br /><br />EDIT: If you haven't done so already, try to locate and check your local outboard graveyards for the prop. You have a very good chance of finding one there.
