In last couple of seasons, my shift lever has started to get sloppy. Sometime of the time, it says neutral pull the starter rope it will start but is in forward, pull the lever forward and the rope will not pull. Neutral seems hard to find. Now the I am having a hard time shifting into reverse. Most of the time, just pushing lever into reverse will not do the job. If I slam the lever sometimes it goes in gear and others times not. If I put into forward and then reverse fast it will go into gear sometimes. When it is in gear it works fine. Looked at the motor, and the only thing a see moving when moving the shift lever is the black cam and the finger that engages the flywheel. No grinding when trying to move lever. Have not hit anything lower unit is full and clean. Is there some type of an adjustment that I cannot see or are we talking lower unit problems. Anyway tests that I can preform. I have a good knowledge of tools. Thanks
