Maybe I can help. Need serial and model number of outboard.
wish4fish can you tell me the serial and model number? I might be able to find an exploded view of the motor. I do advise buying the kit, especial from a local dealer so you can ask what needs to be taken off. I just did this repair for a friend except on a 1995 Mercury 25hp. We learned that on models with a starter (don't know if yours is electric start) that the starter needed to be removed to reach the linkage. Once the starter was off it was a breeze to undo the linkage and get the lower unit off. The retainer clip that held the shift shaft just flipped up, then we slid the shaft off the pin holding it, and voila the lower unit came right off. I do advise leaving at least one of the bolts that holds the lower unit screwed in just a little so the lower unit does not drop on your feet. Like I said, if you can get me that serial and model number, I can probably find some resources for you. P.S I found YouTube to be an invaluable resource.
