Go to http://www.marinshopen.se/ , click on Modellguide, then select Mercury, then find your Hp and serial number. The site is
non-English speaking, but you'll figure it out.

Hi all, how do I determine what year my Mercury motor is? There's no
year printed on it anywhere; I need to buy a book on it. Is the year in
the serial number by any chance?

Thanks
Rog
