    How do you trim?

    Depends on the boat. I'm lucky... my Starcraft Montego (with a 302 mercruiser and a whale tail on the outdrive) doesn't need trimmed when running- just leave it down and run. The only time I trim it is when in shallow dock water. I'm told before the previous owner put the whale tail on it was...

    MC-1 Drive Dog failure?

    Got the drive home. A mix of good and bad news. First, I drained the oil... looking really nice: At the end a bit of moisture, but hardly anything: Tearing the drive down had some issues... first, bozo here hit the wrong spot with the mallet and broke the lower: The shifting was...

    MC-1 Drive Dog failure?

    Cheapest I can get quality bearings (SKF) is $197 shipped... yikes. I'd spend about that (or less) that in gas fetching the other drive. We'll see if I can get a day off... The drive does legit look better than this one. I've attached the pictures from the listing. No corrosion, just lost...

    MC-1 Drive Dog failure?

    I just don't want a failure on the water or to destroy the rest of the drive. Although given what I know about my lower (possibly worn-ish shift dogs), maybe I shouldn't care. Just throw some bearings at it and be done... and if it blows, SEI it in the offseason. The cheapest I'm seeing gears...

    MC-1 Drive Dog failure?

    The other case the guy offered for free (was $100). It's just a long 4.5 hour drive away. Clearly an older one since it has the older "888" logo. I can get gears, but that's a fair bit of $ (plus bearings and a speedy sleeve) and then I have to get all the shimming tools and the like. I'm...

    MC-1 Drive Dog failure?

    I bought an anchor... The gears are worse! Didn't spin smooth. Like at all. Now what? Reuse my old gears and use new bearings? Or fetch the other drive I found this coming weekend?

    MC-1 Drive Dog failure?

    Good news: the oil coming out is water free but looks like generic yellow/orange gear oil. Bad news is the u joints are bad and the upper case damage is worse than I thought: Both sides are cracked. There also is corrosion in the bell housing gasket area. Making a case and joint swap with...

    MC-1 Drive Dog failure?

    Got it. Not as good cosmetically (lower unit has corrosion) under the paint) but no leaking u joint. Plan will be to swap my lower over... Maybe reseal the upper since I have the parts? Obviously I'll have to keep the case and gears together since I don't have a shim kit... Edit: maybe I want...

    MC-1 Drive Dog failure?

    Got the cups pulled too. Lower one was loose (got stuck, but slide hammer popped it out). Upper one put up more of a fight, but I used a light amount of heat to get it out. That said... I was able to arrange a pickup tomorrow afternoon for the unit in Gary. Guy blew his engine last year and...

    MC-1 Drive Dog failure?

    Got the bearings off. The trick for the big bearing (if using the Harbor Freight bearing splitter set) is to cut the cage and rollers off, then pull using the upper lip on the race. I also heated it with a poly torch but it wasn't all that warm by the time I actually pulled it. The cups dont'...

    MC-1 Drive Dog failure?

    Got the seal out. Had to modify a harbor freight seal puller: Also got a bearing splitter for the vertical shaft. How does one remove the bearing cups from the case and cover? Slide hammer? Special tool? Edit- Bearing splitter too small for the large bearing (haven't tried the small)...

    MC-1 Drive Dog failure?

    I showed the worst... but it's like that on several teeth on each gear. If I just need to replace bearings and knock that stubborn seal, then sure. I found another 888 drive to the north of me (Gary, IN 😬) for even cheaper. Worn skeg though.

    MC-1 Drive Dog failure?

    You think my gears are still worth using? I don't recall a lot of gear noise... but the pitting is concerning. If it was just one pit (or a few in one spot), I'd think nothing of it (the cam in my truck was like that when I rebuilt said engine... still going strong). But several teeth on both...

    MC-1 Drive Dog failure?

    My luck may be turning... digging on Facebook Marketplace, I found somebody with a supposedly good MC-1 that happens to be off an 888 like mine (different year due to different stickers, but whatever) for cheap (reduced for not selling in nearly a year). Even has a stock prop (but not likely the...

    MC-1 Drive Dog failure?

    Having issues. First, I'm having no luck with the upper driveshaft seal. I've curled the metal but I can't get purchase, at least with the strike-cap screwdriver I've been using (the lower came out easy since I could use a socket to pop it out). Need to get a different tool that can catch more...

    MC-1 Drive Dog failure?

    Got the drive apart... Funny, the part of the yoke that rides on the seal looks fine... Unless that rusty groove under the shine is the surface in question. Sleeve it? The gears have some very light pitting: Nothing massive... But still ok to use? The bearings feel great... Smooth as silk.

    I may have some sitting... or is it emblem cement? In any case, nothing that one of the LAPS's wouldn't have...

    MC-1 Drive Dog failure?

    Ah. So likewise, I'm not off my rocker for only doing the shift and exhaust bellows... honestly the shift may be OK but since I have the part in hand, I might as well? Per a chat with a previous operator (Brother-in-law of the previous owner who did a lot of the maintenance on it), this sort of...

    Best "low effort" towable?

    Nope, as of yesterday, Airhead says parts for that tube are no longer available. This is on the back burner due to the boat having mechanical issues that'll has it off the water and my boating budget locked out. Unless I stumble upon a deal or something.

    MC-1 Drive Dog failure?

    Coworker loaned me the gimbal tools. Pulled the bearing this evening. It clearly isn't original (as it's the later retainer style, not the original snap ring style). But it had been receiving grease from the zerk, so at least that part was working correctly. Did not remove the seal as I couldn't...
