A friend of mine was checking his lower unit for water while getting his boat ready for winter. Unable to get the drain plug out he removed a small phillips head screw and was able to drain some gear oil. Trouble is the screw won't go back in. THe screw is right next to the drain plug. I haven't been to see it yet but it sounds like what is described on a chart as PIVOT PEN, Shifter lever. What does it do and how do I fix it?I am a pretty fair shade tree mechanic but I have never been into one of these gear boxes. So I'm a little hesitant about taking it apart. Any information tips or help of any kind will be welcome as always. Thank you all for this great service you provide. Using a web page I got here I was able to determine this motor to be a 1992. Thanks again.....Hank
