1998 Evinrude 50 E50ESLECC..clutch dog disintegrated so I’ve overhauled the lower unit. Now, upon reassembly, I can’t get it to shift properly. Motor starts well and while in neutral all seems well. It will go into either forward or reverse and then I can’t get it back to neutral. I’ve had this apart a few times now and while on the bench, it seems to perform ok. When I take off the lower unit, I can’t manually operate the shifter until I take it all apart and reassemble. Feel like I’m missing something here. Nothing changed on the controls and the motor had worked well for many years until the clutch dog ate it’s lunch. Any hints or suggestions? New parts include clutch dog and pin, spring that holds the pin in place, indent balls and new spring, new gears, bearings and seals.
