    Default 1977 Johnson 115 water impeller replacement

    I am looking at replacing the water impeller on my johnson, are there any tips to unhooking the shift shaft from underneath the power head without having to pull the carbs off?

    You don't have to remove the carb. I use a long extension and a flex socket.

    and I assume the same thing on the other side to hold the nut in place, thru the wiring and such?

    Unless you have a rare extra long shaft 1977 115, the shift rod is released by loosening the screw that forms the fulcrum of the bellcrank and spreading the fingers at the shift rod end of the bellcrank so that the pin releases.

    If you disconnect and move the control cables it's easier to reach.

    Be careful not to loose the nylon bushing in the swivel barrel at the top of the shift rod.
