Has been running great for many years now. But now when in forward gear, a hard vibration starts and pushes the gear lever back toward neutral. In reverse however, there is no vibration or shift problem. I have opened the gear housing and things look good with no excessive play or wear anywhere. There is no prop damage and the motor/prop has not hit anything. Any ideas? Thanks for any advice you can give.
