I don't think there is one site that has that, FH.<br /><br />'Rudes have had three different model number systems.<br /><br />There is no code to the first. You just have to look them up. That site is http://www.marinshopen.se/ <br /><br />The second, which I think ran from the early 60s to about 1980 has the year in the model number.<br /><br />The third, which started about 1980 uses the "INTRODUCES" code.<br /><br />Hope that helps.<br /><br />Moving to General Outboard.
