MC-1 Drive Dog failure?

[Eric 3.7LX Alpha 1]

How much more work we talking? When I had the drive apart to do the impeller last spring (2024) I don't recall that portion of the shifter feeling particularly sloppy.

Edit- nah, I'll check it when apart. If it it all is suspect, I'll replace. But if not, I'm reading it can be a royal pain to get the shaft out.

You can use a length of threaded rod and some nuts and washers to make a puller to pull and press the bushings out and the new ones in, not too bad.. the tough part is the arm with the roller at the top. The set screw can be impossible to remove with corrosion and it's easier to split it with a hammer and chisel and replace it with new.
I'd add a tube of 2-4-C grease to the list.

I replaced my cable last summer. '76 MC-1. Had the old style cable. Tapped the hole and installed the new style cable.

Had the old style shift shaft bushing, replaced that too. The old style seal on it was not a very good design and yours is probably failed or failing, which causes bad things. They went to the new style for a reason. You'll probably have to destroy the aluminum shift lever to get it off. This sounds scary and like a lot of work, but it's not. Cheap part. Drill some small pilot holes on either side of the set screw hole, and it will crack right off with a couple of firm chisel whacks.

Gotcha. Ordered Quicksilver 45518T1 which is a kit with the bushings and the lever. The lever roller may be shot anyway with as sloppy as my shifting was.

Grease: I have a grease gun with marine rated grease in it that I use for the zerks on the outdrive. That's what I planned on using for the cable.

That's the part. The one that's difficult is the shift shaft seal beneath the water pump in the drive, that may be the one that you were looking at.

Yep... the one that uses a special "prong socket" and is threaded.
