Re: Are all 1994 Johnson 15hp's difficult to shift?
Drain the lower and see what comes out, hard shifting can be caused by water intrusion, the oil should come out honey colored, darker is fine but white or milky is bad and means you have a bad seal and need to get it sixxed.
I would do this before you take it out again, every minute you run it with water in the lower you damage it, report back what you find.
