I have a 1989 Evinrude 200XP that I bought used. It's a very strong engine and runs great. I'd like to know how the XP models differ from non-XP models.<br /><br />I've read the OEM and Clymers manuals, and I've searched this site. The most I've been able to gather is that the XPs have different carb jets. Any additional info would be appreciated.
