    MC-1 Drive Dog failure?

    Did some checking on the other two lower cases I have. Pulled the TN drive's impeller for laughs.. yeah, it was completly roached. Didn't take out the housing... but no wonder the guide tube was melted! Due to the case damage and stiff shifter, it's not favored for reuse. The Gary drive needs...

    MC-1 Drive Dog failure?

    Spent a bit fiddling with it. I already had it at 6"... I eventually found a setting (backed off helm cable 6 turns instead of 4) that allowed for full engagement both directions and not using up all of my slot adjust (still using about 70% of it). Here's a video of my current results: I...

    MC-1 Drive Dog failure?

    Redid the adjustment last night. I did have something wrong (forgot the 4 turns on the helm cable) but if anything (also using 5 7/8"), I now needed to use almost all of the slot to get reverse to solidly engage. I measured my helm cable travel at 3 1/6" on the new setting. It does very lightly...

    MC-1 Drive Dog failure?

    Did some more checking while getting the boat covered up tonight... seems there is some light ratcheting in neutral, so maybe I don't have it right. I did use 6" on the last adjustment... maybe I should have used 5 7/8" for the initial set point. I'll mess with it this week.

    Name or part # for MC-1 Hook Thing?

    All three MC1's I have for my 1976 (the original 1976, one that's the same age or a bit older, and one that's a later build, all 888's) have the hole. And I am very grateful for it (I've been in outdrive heck the last month, but that's my other thread's story). Probably was a pain to die cast...

    Still not working.

    MC-1 Drive Dog failure?

    Pulled the throttle... what a pain. For future reference, if one has a morse controls throttle like this, shift full reverse or else the shift cable lever won't allow it to exit the gunwall. The shift linkage had a second cable attachment hole that gives a roughly 1/4" greater swing of the...

    MC-1 Drive Dog failure?

    I tried it both ways. Little difference. And yes I did move it all the way in the slot to try to make it work.

    MC-1 Drive Dog failure?

    Back to square 1. Shift cable adjustment still not doable. I fiddled with it and got it a lot closer than it had been (both directions catch but just barely and can be pushed past). Seems the issue is the helm cable. I'm only getting 2 21/32" of throw (should be 3"?). The lower cable is much...

    MC-1 Drive Dog failure?

    Better news: it's on! Did some testing with the old input shaft and old gimbal bearing and determined the issue was surface rust on the new shaft hanging the bearing... Wasn't even hitting the o rings. I wire brushed the shaft until the old bearing slid on comfortablely and replaced the o rings...

    MC-1 Drive Dog failure?

    Good news! It's off! Used the 2x4 and trim ram trick. Bad news is I cheesed the second gasket a bit at the very top. Not completely torn but not great. Still ok to use?

    MC-1 Drive Dog failure?

    I've done it... Tried giving the drive some light dead blow taps and now have the shift jammed in the bearing. Having no luck getting it out in a way that doesn't skewer my other gasket. I'm thinking this input shaft still has rust in the o ring grooves. May be better off trying to swap the...

    MC-1 Drive Dog failure?

    My coworker had an expander tool... So the bellows are done. Shift cable fought like a stubborn mule but I made do there. But the drive install is not going well. Gets stuck 1" out... I suspect that's the o rings on the gimbal shaft. I installed the ones that came in the upper seal kit... But I...

    MC-1 Drive Dog failure?

    Of course... that's partially what deep sixed my upper gearcase! Bellows adhesive or aviation gasket maker (perfect seal)? I'd think the former since it's metal to rubber? Maybe slightly. The issue is that the plastic tube sticks out farther than a normal deep socket (with a ratchet plugged in)...

    MC-1 Drive Dog failure?

    Frustrating day. The theme is "messed over by tools" (what I wanted to type is a bit more colorful, if you like!) First issue was getting the shift cable threaded into the bellhousing. As it turns out, I erred by buying a cheap socket on eBay. (file uploads aren't working, so no pic) Notably...

    File uploads no good again?

    Seems for me today, that file uploads are failing in the same way they did back in August of last year: https://forums.iboats.com/threads/photos-not-saving-to-server.773767/ Had it both on my phone earlier and now on my laptop... both were on my WiFi so technically it could be ISP related?

    MC-1 Drive Dog failure?

    More work done today: Shift cable and bellows removed (I ran some coated wire rope to maintain the routing). Bellhousing tapped. Didn't cut metal; seems the threads were always all the way thru and the tap is just to clean junk from said threads? Per my prior posts, swapped shift shaft...

    MC-1 Drive Dog failure?

    Sloppy on the shaft.That said, from what I'm reading this is common/normal.

    MC-1 Drive Dog failure?

    Working on the bell housing and having an issue. Seems the new lower bushing is very sloppy compared to the old bushing. The upgraded upper bushing fits the shaft fine. Is this intentional? Or am I correct to put the old bushing back in?

    How do you trim?

    Well, trimming up historically didn't do that for me. No change.
