Hi all, here’s my engine…
  • 1973 Johnson 50hp, long shaft, electric start
  • Manual shift with hydraulic shift assist pump (as far as I can tell)


As I disassembled the gearcase, I was expecting to find some detent springs and balls, but there’s weren’t any in there. I don’t really trust what was in there when I disassembled everything, based on some other signs of bad service in the past.

Here’s my question: how many detent springs and balls should there be, and where should they be?
  • The marineengine.com diagrams show 1 detent spring and 3 detent balls (items 69 and 70 in the diagram below)… Not sure where they would go.
  • The Seloc manual has a diagram on page 7-86 for this model, and everything looks like it’sa match to what’s in my gearcase - other than the fact that there’s no spring or detent balls. If I’m supposed to have them, where would they go?


Here’s the me.com diagram.

Attached is a photo of what parts were in there (mostly disassembled).
