What does it look like ?<br />Blue band ? <br />1 or 2 shades ?<br />Silver "Mercury" text or white?<br />What sort of cowling cover ?<br />1 piece wrap or other?<br />These all help ID the year as well as Ser No's

Bkusa<br /><br />I reckon it's a 1982.<br />Serial no's are tricky as Australian, European, Canadian, and USA all start with different no's so the charts mean very little.<br />I have been trying to find my year for ages as it's an Aussie no.<br />This is a reply I got from a Merc site and it seems to be the most accurate. That is the reason for all the questions.<br /><br />"Have a Merc 50 (not 500) Australian ser 8055895<br />4 cyl - 2 blue bands. Elec start.<br /><br />Clymer manual says the 1978 model is still called a merc 500, So I would say it's between then and 1980 but not sure. <br />Any ideas ??? <br /> http://www.myfishingpictures.com/img/003940.jpg <br />"Unicorn..<br />Looks like an 81 or 2. 1984 started the brown decal and 1979 still had blue with splattered black. 81 Mercury was in silver and 82 in white. Hope that helps."<br />Mercpro"<br />Bkusa upload your pic to the above site or similar.
