Re: 1982, 35HP Lower unit philips screw; ? re-insert ?
you've managed to remove the screw that is the pivot point for the shift lever. you'll need to fix that.
if you look at the screw you removed, you will see that it probable only threaded towards the head
if you use a awl, dental pick, or something else, you may be able to manipulate the shift lever enough to see the hole in the shift lever that will allow you to put the screw back in. if not, if you remove the rest of the bottom screws that cracks open the lower gearcase housing, you'll figure out what you've done real quickly, but I'd work with that awl for a while, before going whole hog on the lower unit.
you might be able to get some movement of the shift lever by jiggling the f/n/r. good luck.
