I've had my '98 Model: J4 / E4, gearcase apart several times- (2.5hp & some 3hp are the same). Yes 2-cylinder, 2-stroke of course.
What's happening; propeller is slowly turning in neutral and in gear, ("barely engaged") but does not engage any more than this when shifted in forward gear. Yes the shear pin is good, and the prop is not the type to spin the hub.
I've studied how it works and the shift rod is not bent. (it moves up, out of the way to engage)
I might need a new set of eyes on the problem. Only possibility I can see at this point is the spring broke, (perhaps) just a little length off of the non engagement end- and is not as thick as it could be, despite looking normal. I'd kind of like to figure out for sure if this is the issue before throwing a $50 replacement part (spring) at it, or starting a hunt for a used lower unit.... So in desperation I tried a shim, 1/10" (~2.7mm) thick washer in there on the non engagement side of the spring, and the result- engine was fully stuck in gear no matter f/n, etc.
Is there anything I can look for on this model? or tips from experience (some other johnson evinrude 's use this same system going further back in vintage). - I've compared the parts diagrams, thinking someone previously left something out (I picked this up as-is) = it's complete, looks brand new so I doubt wear is the issue, but checked anyway..no play on that shaft etc either as far as bushing wear or similar movement goes.
I guess I'm going to try another shim half the thickness, But ANY input or encouragement/experiences would be greatly appreciated! thanks in advance
