I have a Johnson 25 Horse Motor model 25RL69D

I replaced the water pump and I thought it tested ok in my bucket. But when I took it out to the lake the Neutral and Reverse worked but not forward. I read on the forum that I may need to turn the shift rod because it's threaded, is this the case? May not be for my model I didn't see it in my book anywhere but neither did the other guy. But I bet I turned it putting the water pump in. I moved the crankshaft just a little but I figure I'm ok because none of the gears would work. It ran fine all last year. Thanks for all the help.

Re: Changed water pump gears stuck in reverse

Hi Rosco, sounds like you did not get the gear shift conection back together correctly.
If you drop the lower unit about 3/4" you will see a small rectangular coupling that conects the shift rods together, you would of had to have taken this apart when you changed the impeller.
Remove the same bolt from this coupler as you did last time (normaly the bottom one) then move the shift lever into forward, the 2 parts of the shift rod should part company, take a look at the shift rod that comes out of the LU you will see a groove cut into it, this groove is for the bolt to fit through. What you need to do is pull the shift rod that goes into the LU up (you may have to turn the prop while doing it) there should be a noticable clunck when it,s pulled up far enough (you have engaged forward gear) now put the shift lever into reverse. Now when you reinstall the LU you will be able to get the shift rod far enough up into the coupling for the bolt to fit in the groove.
As you push the LU up to the mid section move the shift lever into the forward position.
Sorry this is a little long winded, I'm sure as soon as you see the groove in the rod you will understand.

Re: Changed water pump gears stuck in reverse


Hi I went home last night and worked on the gear shift rod and just couldn't get it. I have the model of 1969 25 horse that has a window and yes it does have 2 nuts and the bottom nut fits in the gear shift rod but the rod has a knuckle not a notch and I just can't get it right. I'm going to take off the LU maybe I bent the rod however I doubt it. The rod slips into the bracket ok and maybe it's me because I've never done this before. I'll see if
I can figure this out but any ideas would help.

Thanks
Roscoe

Maybe this diagram will help: Just make sure the "Indented" part on the shift rod is lined up with the bolt hole on the top and bottom of the connector..

Re: Changed water pump gears stuck in reverse


Thanks for the response Rick. It fits into the 2 nut
bracket fine. Do you know how the shift rod attaches
in the gearbox? Or is that a factor? Does it just slide
in place down into the gearbox? I tried to move the
shift rod up and down in the window with a pair of needle nose pliers.That's such a hard space to work in.
I worked on it all last night and all I could get is one direction couldn't tell if it was forward or reverse. But I bet it's reverse.

When shifting the shiftrod up and down, you need to turn the prop so the clutch dog lobes and the gear lobes will engage. You might be getting lobe on lobe for forward.

Turn the flywheel (always clockwise) and watch the prop shaft. If it turns clockwise, it's in forward and vise versa for reverse.

Re: Changed water pump gears stuck in reverse

Thanks OBJ for the help. I've read my manual for the last 2 weeks and I'm not getting anywhere. I'll go home tonight and try what you suggest. My gut tells me that it's just something simple,, but I'm missing it.

One of the guys told me that it sounds like the shift rod coupler in the gear case is out of position. It sounds like to me I'm going to have to take off the lower unit and put the lever back inplace in the gear case. What do you think of that? Let me know.

Thanks
Roscoe

Re: Changed water pump gears stuck in reverse

Oh one last thing OBJ. When I have it in gear I cannot turn the prop with my hand I tried last night. The only way I can turn the prop is by pulling my rope. I did'nt put a lot of force to turn the prop with my hand, did'nt want to break anything.

So do you mean I to need move the gearshit forward and pull the rope and then move it into reverse and pull the rope, I've tried this. Or do I force the prop to move with my hand after I shift. I need to just put a little more force on the prop with my hand and it will move after I shift? Just asking, Thanks

Scanning through the thread, didn't see anyone mention that you have to remove that lower fastener in order to get the shift rod in properly. It looks like it'll all work with it loosened, but you have to remove it entirely.

I kinda learned that the hard way.

Re: Changed water pump gears stuck in reverse


What lower fastener are you talking about? As you can tell this is all new to me and I'm just learning? When I changed my water pump I didn't put on a fastener. Are you talking about the coupler with 2 screw nuts that holds the gearshift together? I just loosened the screw nut and slid the gearshift rod in and out and tightened it down. Are you saying I need to remove it and put it back? I did'nt see that in my book, but I think it's something like that, that is my problem. Just asking. Thanks

Re: Changed water pump gears stuck in reverse

Review the part diagram above are we saying in order for the shift to work corrrectly I must take out part 6-7 and 8 realign everything and bolt the shift rods back up? When I did it, It looked like it will work but maybe this is what I need to do.

Re: Changed water pump gears stuck in reverse

You have to totaly remove the bolt from the coupling, then push the shift rod into the coupling untill the groove lines up with the bolt hole then replace the bolt. Part# 6

Re: Changed water pump gears stuck in reverse

iwombat and RPJS were right. You see my problem was it looked like it should work that was what was causing me the problem. I guess some of these things you just
got to learn the hard way. I lowered the unit removed bolt and work the shiter to get the gears right. Put it back to gather with the coupler and it worked fine. Thanks to everyone for the help. I'll be rebuilding my
the gear box this winter.
