    Default "Greetings, wish I was coming

    "Greetings, wish I was coming here under better circumstances, but unfortunately I need help with a fix instead.

    I have a 1986 Johnson J40ELCDE. While duck hunting last fall I had an unfortunate encounter with a log or something hard while up on plane. The collision knocked the motor up out of the water locking it in the tilt up position. The resulting inspection revealed that the prop would not turn freely, with light pressure it will skip along the teeth of the gears. The shifter still shifts between F-N-R with no problems. There is no visible damage to the lower unit housing. I've been told by a friend that I've done something to the lower gears. Is that a correct diagnosis?

    Secondly, I've found a reconditioned 1982 lower unit from a 50 hp OMC. By the information I've been able to gather, this should be compatible with my motor. Can anyone verify that?

    "Thanks guys.

    I got a really good deal on the other lower unit, actually less than what a new set of gears cost. It has been completely gone through, new seals, water pump, pressure tested, etc. Got it from a guy who is reducing inventory in anticipation of retirement. His son indicated to me that getting the shift linkage loose and hooked back up can be a real pain on these motors. Anyone have advice on how to best go about that and minimize that pain?!?"
