Need help what year and size motor?

[ntoracn@yahoo.com]

My fater in law purchased what I think is a 1998 6 hp 2 stroke 2 cyl Evenrude outboard for $250. The dark blue paint was covered with a camo paint job. The previous owner removed the id sticker. I have only been able to guess at the year based on the date of MFG stamped on the flywheel (10/7/97) and a date of 10/17/97) on a sticker attached to the carb. That sticker also says "made in mexico" and has a "102797" number below the date of MFG. It has a cotter pin holding the prop on, if that helps. <br /><br />The problem he's having is it won't plain his 10' infatable at lakes over 7,000'. I pulled the carb and found a "38" stamed on the main jet. the motor runs fine at idle, but runs way too rich off idle and starts missing when you try to open the throttle.<br /><br />Just trying to figure out if it's a 6 or 8 horse motor so I can order the proper jet for high altitudes. Is there anywhere else I could find the motor numbers with out the sticker?<br /><br />Thanks in advance.
