Howdy! I have "come into" an old Mercury outboard and can't seem to be able to figure out how to get the cover off to start to service it (haven't got service manual yet). It's a 7.5 HP motor Serial No. 3456974 (based on this, I have determined that it is a 1972 model). There is a number 2 decal on the aft end of the cover. There are a pair of levers tucked under a frame that rotate downward, but I don't see that this immediately does anything. Any ideas? <br /><br />Thanks! -djm
