    1972 Johnson 125 Power Tilt creeping problem

    1972 Johnson 125. The power tilt creeps down fairly rapidly (e.g., <2 min. to fully lower) after being raised. I'm not sure what position the release valve is in because there are no visible markings and it's just a slotted screw. How can I figure out the position of the release valve...

    Hydro Electric solenoid test issue

    Hi, I need to test the shift solenoids on a 1972 Johnson 125 hydro-electric lower unit. The powerhead has been removed. I've performed the ohms test which the manual says should produce 5-7 ohms on the green and blue leads. I get a reading of 6 ohms on the blue wire but over 8 ohms on the...

    Function of power trim/tilt buttons on1980 Merc 115

    Dumb RTFM question, but I don't have an operator's manual, the shop manual doesn't help, and I can't remember from years ago how this is supposed to work. Can someone explain how the three (3) buttons on a 1980 Merc 115 HP outboard power trim/tilt control are supposed to work? The buttons are...

    Installing lower unit on 1980 115 HP Merc outboard

    Having trouble installing a rebuilt lower unit on 1980 115 HP Mercury outboard. I have a 3/4" gap between lower unit and driveshaft housing and don't want to start forcing it. The prop shaft splines seem to be aligned, as I can turn the flywheel clockwise and the prop shaft turns. The water...
