Just above the lower unit on one side of the exhaust housing, you will find a small metal plate with two screws holding it on – take that off and you will find a 2nd similar plate under it in the next housing – remove that too and you will find a coupling on the shift rod that has to be undone to get the lower unit off. You may have to move the gearshift lever to get that rod coupling bolt lined up with the access hole so you can remove it – you have to take the bolt out all the way because it goes into a curved slot in the rod. Be careful not to drop the bolt between the housings. When I reassemble, I use a small piece of duck tape to tape the bolt head to the outside of a socket wrench – this makes starting the bolt without dropping it very easy.
