Clutch dog?

I have just purchased a 1974 evinrude 9.9 for 50 bucks. It runs but is stuck in forward. I finally git the lower unit removed, it was a pain because with it being stuck in forward the shift linkage was near impossible to disconnect. Got it off and the problem is in the lower unit. I can get the linkage to move up and down but only with extreme pressure in each direction. But I can get the lower unit in forward neutral and reverse, so it works but only when basically hammering the linkage up and down. Im thinking maybe the clutch dog is acting up one way ir the other? I should be able to move the linkage up and down fairly easily correct? I drained the oil, no water or milky oil just very very black. Refilled it but to no avail. Was wondering if there are any known solutions to this problem besides taking apart the lu? I was thinking of maybe draining it and pouring some seafoam in there in hopes cleaning and freeing things up? Any help would be greatly appreciated! Its also a long shaft but don't think that makes a difference.

Re: Clutch dog?

Look at this diagram:
http://www.boats.net/parts/search/BRP/JOHNSON/1974/10E74G/GEARCASE/parts.html

The shift rod just goes down into the gearcase and pushes on the shifter lever yoke assembly to move the dog. It's possible the yoke is having issues and won't move freely. It seems more likely that if your dog were worn out then you'd be having trouble staying in gear rather than getting into gear.

I'd keep the seafoam out of there personally.

Re: Clutch dog?

Yea that's the same diagram I was looking at on marineengine.com. After looking again I realized that it was the shifter yoke I was looking at not the clutch dog. I jusr must have gotten the part name mixed up. So that's exactly what I was thinking, maybe its binding up somehow or has partially seized up. Any suggestions as to fixing it other then taking it completely apart?

Re: Clutch dog?

I'm afraid you're going to have to tear into the gearcase to see what's going on. Could be a number of things, including a broken yoke, cradle, or corrosion. You didn't pull the Phillips Head pivot pin, did you?

Change the shift rod seal. Clean shift rod and seal groove.

Re: Clutch dog?

Alright so I un screwed the shift linkage from the LU I then turned it upside down and ran some gear oil threw the fill hole until it came out if the shift linkage hole. Basically trying to flush any thing out and run some fresh gear oil over the joke. Cleaned ands reinstalled the shift linkage and it moves pretty freely!! It will go up and down with much much less force then before. I can actually move it up .and down by hand. I put it back on the motor but must have not ran it correctly because it wouldn't move again. Took the lower unit back off and I can still move the shift linkage by hand so im sure I ran it wrong. Thanks for all the help. Luckily I didn't have to take it apart.

With the amount of force you describe I wouldn't be surprised if you bent the fork. Best of luck. Rick.

Re: Clutch dog?

Not really sure, what is the fork exactly? I did apply a lot of pressure, just tried again to install the LU but again it wont move. It'll still move with it off the motor though. Maybe I did bend it, what is the fork though?

Re: Clutch dog?

Is the lever moving freely on the engine with gear case removed?

SHIFTER LEVER AND YOKE ASSEMBLY is the correct part description. Sorry about the confusion. Pulling the gear case apart isn't that difficult a task really. LeeRoy gives a good description and pointers on how it's done here. http://www.sschapterpsa.com/ramblings/Ramblings.html Rick.

Re: Clutch dog?

I don't think I bent the yoke I mean it will shift freely when removed from the engine. Or could istill have bent it? I think I might just be running theblinkage wrong. Im an idiot though, I struggled to remove the lower unit originally for about two hours do to the shift linkage being stuck down and not being able to remove the pin because it sits down in that hole in the engine bay. I didn't realize until now that I could have just dropped the LU down the half an inch it falls and unscrewed the shift linkage from the LU via the little brass connector! I guess im still learning as im going. Only have removed the lower unit of a motor once before. Was sighting there wondering why the he'll they designed the shift linkage in two pieces! I guess I know now.

The shift lever does move freely on the motor. Ill connecting it again today, hopefully itsbsomething im doing running the linkage!
