Re: shift rod disconnect 115 EL77S Johnson
I have a 1973 85 HP...but after reviewing the schematic for your engine, suspect yours is the same set up.
The shift rod extends up the exhaust housing, and connects to the engine just below the carbs.
I found mine when looking from the starboard side...look under and behind the carbs. I then removed a bolt holding the shift linkage to the block, which allows you to spread the arms holding the pin to the shift rod. I could then reach in with a long needle nose pliers to remove the pin/bolt which is holding the shift rod to the shift linkage. Good luck...not really difficult...just irritating.
