I posted this a few months ago, but I'll try again.... Last year I bought a 15 hp evinrude that <br />looks to have been the victim of abuse. Mechanically the motor isn't bad... it needed a few <br />things done (which I have taken care of), but aesthetically it's a bit beat up and scratched. <br />In keeping with this general "unloved" look, the I.D. plate is missing. On the frost plug, there <br />is a number (presumed serial number) stamped, but there are no letters etc. in that, like should be <br />in the model #.<br /><br />I've read things that say that the ignition systems changed from say '76-early 80's. Is there<br />a way to tell by looking at it whether it has a newer ignition system (and then be able to figure out<br />approximate year), or whether it has an older ignition system? So far all the parts I've needed are<br />the same across these years, but I realize that some things might not be, that's where it'd be nice<br />to have a good guess as to what model it is.<br /><br />Thoughts?<br /><br />Brent
