    How do you trim?

    Nothing much added from stock in terms of weight. That's a 302 in a 16' boat... the biggest engine Starcraft offered for this model and length. I'm told the whale tail helped a lot as it did have issues getting on plane originally. In current form, I wouldn't say it handles "bad"... although...

    MC-1 Drive Dog failure?

    I've begun the reassembly work (after cleaning all the metal chips out of the case, three times over... that stuff is persistent!). I did use aviation gasket maker (permaseal) on the case side of the water pocket gasket to address the gouges in the surface. I also used it on the driveshaft seals...

    MC-1 Drive Dog failure?

    Ideally one would use a metal block. Based on how much of a fight the other bolts put up, I figured helicoil was going to be a given. Not to mention I didn't have high hopes of the aluminum threads being in good shape based on how much likely had become corrosion. Helicoil is theoretically a...

    MC-1 Drive Dog failure?

    No, if there isn't a reason to expect trouble, don't mess with it. The reason I pulled it was partially because I already installed the new pipe seal in the other pocket (and was too lazy to try to move the seal), and partially because having noted what is likely a severe impeller failure in the...

    MC-1 Drive Dog failure?

    Well.. that's what I did. Using the old water pocket! And spoiler alert, it did work. First, here's the tooling I bought: Milwaukee Shockwave 17/64" drill bit 12" DeWalt locking 1/4" hex extension 1/4-20 Helicoil (Note- you want a name-brand install tool for clearance reasons- "other" brand...

    MC-1 Drive Dog failure?

    I haven't tried to pull the pocket from the gary drive... I'm going to try another home solution tonight or tomorrow. The plan is to use a water pocket as a drilling guide and a Milwakee Shockwave 17/64 drill bit (which has a 1/4" hex shank) with a 12" drill extension to drill the holes for a...

    MC-1 Drive Dog failure?

    Against my better judgement I tried to weld some nuts to remove the broken bolts... nope, the bolts just kept breaking internally. Once it got below flush I stopped. My nuts messed the surface up a bit, so that may need to be decked while it's in the mill. The things I do to try to get out of...

    MC-1 Drive Dog failure?

    Got the drive back... they did have to helicoil it. But... more broken bolts, this time in the water pocket: I used my impact on its lowest setting. The two that didn't break I used a 1/2" drive 11mm shallow with an extension (my SAE impact selection isn't too hot). The two that did I had to...

    MC-1 Drive Dog failure?

    I have the shop working on it... no luck welding, it's going to the mill. They weren't comfortable trying to free the trim cylinder pin (without machining it out, more trouble than I think it's worth), so it's just going to be a captive part (makes installation a bit harder, but whatever). Based...

    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)...
