I'm new here and have searched, but can't find exactly the same problem I'm having. I've got a '79 or '80 (ser #5086064) merc 20. It ran well last time it was run 5 or 6 years ago. I just finished new jon boat and rebuilt carb on motor to be safe. Got to the lake and the motor ran great the pisser wasn't pissing. At first I figured just dirt dobbers as always, but after cleaning pisser and tube, it turned out to be be the impeller. Should've known after sitting that long.:facepalm: I ran into town and got a replacement impeller and had it installed in no time. I've changed it before on this motor with no issues years ago, but this time when I launched the boat I had three fwd gears. I've disassembled the LU probably 50 times and reinstalled with the shift shaft/shift lever in every possible combination and no matter what I do I come up with multiple fwd gears. The best luck I've had yet was a neutral and two fwd's. I successfully got it installed with both shaft and lever in neutral tonight and all was well until I cranked the motor and it only stayed in neutral a second or two before returning to fwd in all three shift positions. Any ideas? I suspect I'm missing something really simple, but the manual is pretty vague(clymer) and I'm just not that familiar with outboards. I've built and run many race jetskis(standups), but their drivelines are much simpler. Thanks in advance!
