I know ....another lower unit question. I have all the bolts out of my 66 650 merc lower unit, except for one. I am an aircraft mechanic by trade and as such it pains me to see such crappy manuals out there for folks to use. All I lack to drop my lower unit is the bolt at the rear of the unit that holds the trim tab into place with the lower unit. Any one have a size on the bolt that does this? Its about 6" inside the hole and I can't for the life of me see that far into it because my glasses wont focus that close (it sucks getting old). I can see daylight all the way around the unit except for this place so I am reasonably certain that this is the part that is holding me up. Thanks for any help you can throw my way!
