Re: Johnson 130 lower unit
It may be a clip or it may be a bolt depending on your model. The best thing to do is have someone shift it from forward to reverse while you look under the carbs. If memory serves me correctly you'll see the linkage move up and down and that's what you need to connect. It's a shaft that you'll only see the end off coming up from your midsection into the lower engine cover through a rubber grommet (provide the grommet is still there). It's tight in there but you can get to it and it's easier to disconnect wiring and give yourself room instead of trying to work around everything.
You'll likely need a friend to help bolt it back up because you have to have I think 3 things lined up perfectly in order to reconnect.
You might also be able to see the shaft move by looking on the port side of the motor under the upper cover where the midsection connects to the upper cover. Right by your steering arm. Although to disconnect it you have to be inside the cover of course.
Good luck. If you really need a picture take some of your motor, under the carbs, post them for us and we'll point it out.
