Hi guys
This is a bit of a newer motor, but the question may interest others:
This is a 1992 6 hp Johnson outboard. This is the newer style with the one piece gear case and a one piece shift rod that goes all the way up to the powerhead and links with the front mounted shifter. The shift rod turns horizontally and appears to drive a cam in the lower unit for shifting.
PROBLEM : I got this from a guy who basically gave up when he tried to change the water pump and pulled the shift rod out by mistake. He put it all back together but although the shift rod will move, it does not engage anything down below and the motor is in neutral.I want to reset the shift rod, but I’m not sure how to remove it and reset it. I do not want to dislodge the drive shaft at the same time. My idea is to remove the water pump housing and slide the plastic lower unit housing up on the driveshaft so that I can leave the driveshaft in place while I check what’s going on with the shift rod because it will pull up with the plastic housing.Any suggestions would be appreciated.I have looked at numerous videos online but none of them seems to address this 6 hp lower unit ( 8hp is similar).Thanks in advanceDaveApril 27, 2023 at 2:22 pm #275662the shift rod is flat one side to fit in part #29 the cam shift
never done one myself but have you tried rotating the rod till it lines up the flat section and drops in the cam shift part #29 which then pushes on the shift dog pin #12

April 27, 2023 at 3:25 pm #275672OK, well I guess you do want to avoid pulling up that plastic upper gearcase cover. Cleaning up the old sealer, and resealing this part is a real hassle. The problem is that the gearcase is in neutral, so that big spring has most likely pushed the cam out of the way a bit so the hole in the cam won’t line up with the shift rod when you push it in. There is supposed to be a retainer clip on that shift rod under the upper cover to prevent it from coming out, but it could have fallen out I guess.
The other issue here is that this is one of those “ball shift” models as shown in this diagram:
Evinrude Gearcase Parts for 1992 6hp E6RENM Outboard Motor (marineengine.com)
So, if you remove the rear prop shaft bushing/seal hsg and prop shaft, those pesky little shift engagement balls are likely to fall out of place.
Are you sure the gearcase is in neutral? I would thought that the spring would have pushed the mechanism back into the forward position, but who knows. I guess I would drain the oil out completely, then try installing the shift rod again, while moving the gearcase to several positions that might help the cam fall back in alignment. You will need to be rotating the shift rod as well while trying to install it, the flat in the shift rod needs to line up with the flat inside the cam as well. Keep trying this buddy, perhaps have an assistant help you. You really want to avoid disassembling this unit if possible.
Let me know how you make out. Don

April 27, 2023 at 8:13 pm #275685Thanks guys. I will try rotating it back into place, because I really don’t want to dissemble the whole thing. Will post updates.
Ironically , the last guy didn’t line up the impeller drive pin correctly and then it still didn’t pump water and that’s what caused him to dislodge the shift rod on the second try ( and then give up)
April 27, 2023 at 8:49 pm #275690Good plan, avoid disassembly if possible. Tip that gearcase in every direction while rotating the shift rod inside, hopefully it will drop back in place….I would drain the oil out first though, the cam will flop around more easily without being in the oil bath.

April 28, 2023 at 10:52 am #275699UPDATE
I did try rotating the shift shaft but no change .
To clarify, the shift shaft is not out of the lower unit. The motor was totally assembled and the shifter easily moved the shift rod from side to side, so it is where it should be, but just not likely inside #29 the shift cam ( which must have been pushed aside). So that’s why it seems like my only hope is to slide that gearcase cover #25 up the driveshaft and peek in and see if I can re-set the cam and then set the cover ( with shift rod still in it ) back down to seat into the shift cam.
Is it that simple or am I just dreaming that it is?April 28, 2023 at 10:57 am #275701try anything that works …have a borescope to peek in ?? maybe try a smaller thinner rod to line up.. jiggle the cam…then push in the shift rod
that strong spring pushing #29 may may impeed all efforts but who knows ….

April 29, 2023 at 1:03 pm #275746Sure, it is easy to slide the plastic cover upwards, it is the resassembly/sealing that is a stinker. Trying to clean that plastic is near impossible, very difficult to reseal properly. You might get lucky and have the gasket either stay in place or stick only to the cover when you slide it up, but I wouldn’t know anything about that kind of luck. But, in the end, you may have no choice. Be sure to order a new gasket, and the retaining clip that is supposed to be on the shift rod to prevent it from pulling out of there in the first place.
PS: If you do have to replace the gasket, be very careful. The gasket is “almost” identical/symmetrical, but not quite. It will fit in place the “wrong way”, so be sure to make sure you have it right.

April 29, 2023 at 1:17 pm #275747must have designed by an antique Egyptian architec….. pull one piece out and the whole thing collapses to keep thieves out 🙁

There is supposed to be a retaining clip on that shift rod, underneath the cover, to prevent accidental removal.
