I'm trying to find the year. I tried the Evinrude links with no success. Can't seem to get to docktalk. I took this # from the frost plug co420197, but my local dealer says it's meaningless--not a model #. The motor was stored for some years and is partially seized, at least, it takes all I have just to turn it over. Before I resort to a teardown, it would help to know if parts are available, cost etc. All suggestions welcome. Grumps.
