Need model/year for Evinrude O/B

[Brase Bear]

I have a 25 HP Evinrude that's missing it's ID plate, with the following info on the powerhead plug:<br /><br />25502B<br />E0004031<br /><br />It currently has NGK B6 S spark plugs installed as well (I've heard that can help narrow down the year). <br /><br />If anyone out there can assist with identifying the year and model I'd appreciate the help. Please send responses directly to my email listed below.<br /><br />Thanks, Mike<br /><br /> brasebear@yahoo.com
