Try the Johnson Evinrude forum at The iBoats forums Quote the model details, you'll only be asked if you dont, including the year, if you know it, and the model number (not the serial number).

You'll have to register but it may well prove to be useful any way.

You'll find patrs lists and exploded engine diagrams on the BRP website It may give the Champion plug number.

Otherwise you may be able to find the NGK plug type from This site

BTW your Avatar does not show because you have not uploaded to the forums or put in a link to it on a photo hosting site. It is trying to link to your own computer. I guess you can see it for that reason!
