Just purchased a duck hunting boat and it has a 78 Evinrude 55hp motor. I am having trouble getting the actual shifter/ throttle into neutral and backwards into reverse. I disconnected the linkages from the motor and it shift fine (motor linkage) but the actual shifter seems to get stuck. I took it apart and figured out how it worked but did not fix the issue. Any suggestions? I greased everything especially part #64 on the manual. It looked like it jumped the shifter teeth so I put it back on and it will only go forward about 3 inches but will go all the way back in reverse (should be opposite). Any help would be much appreciated. Thank you.
