Hi all <br />I have been reading through the forums for the last couple of days to find an answer to my questions with no luck, si I thought I would ask the experts here<br />I have just picked up an old evinrude part of the front cover is missing but I can see the word sport, the motor is a little direct drive and it looks like you fold the handle and spin it around for reverse. The covers are painted blue aluminum <br />The motor itself is a one piece single cylinder with no separate head <br />There are no info plates anywhere on the motor but there are the numbers 550590 stamped on the cylinder <br />any info would sure help a lot<br /><br />Thanks <br />Rob
