    Very, very nice...but no-one likes a show off 🤑

    STILL no word on " our " area opening up,
    the CSIRO boat was out today taking samples, apparently has to go to Sincity to be tested, min 2 weeks so not looking like we will be able put our own pots out for chrissie dinner

    And not dragging a Swiftcraft Stilleto dressed up as a wakeboat a 100ks up the road and then out into the Tasman for an overgrown yabby,

    Could buy a lot of crays, even at retail prices, for what petrol or diesel costs to take either bigger boat out,

    so will probably just walk down to the marina and get one or two of a commercial boat closer to the day,

      hey Chris - nice to know bad stuff happens to the pros too haha.. curious - whats your take on scuffing the cap surface and using bearing retainer sealer, they have various ones depending on the wear.. and a new race of course.. i guess it would not be shimmed correctly? but might get u thru? if the back lash on the drive / input yoke is within spec it shd be ok? or not?

      For example loctite 609 retaining compound

        I did this with my top race last spring. After setting the driven gear height, shimming for preload/rolling drag/rolling torque. (International forum here, gotta respect the colloquialisms). Then I pulled the race, cleaned up with acetone and pushed it back with whatever Loctite 6xx green bearing locker I have in the shelf. My race hadn't spun, but it had a weak press on the cover. I patched another less-than-press fit joint with the green stuff. I was in a hurry to get on the water to salvage the last 1/4 of the season.

        I'll tear it back down this winter and replace the suspect part$. That top end works fine if everything is w/in spec. I don't want an outdrive explosion in front of a 15 barge consist, or a lock and dam.

          Last week was March-like warm, so I finally built my outdrive cart/stand. I had to back the trailer tires on a pair of 2 xs to get the boat 3" up so drive would clear the garage floor. My sore old back thanks to all who showed me examples of their carts.

          Good news is alignment is good. Bad news is my drive shaft bellows is also full of lube. But I think I know why. I did a reseal job last winter and I guessing I installed the yoke shaft seal backwards - garter spring out. Dyslexia. I'll know shortly.

I can replace the shaft along with the seal, but if the sleeve is a thin (w/in seal tolerance) slide on, loctite on repair, I may go for that instead. Any thoughts and references? Thanks.

                  You have a couple of options. If the area forward of the seal isn't rusted, then you can set the seal about 40 thou deeper into the carrier. It will then ride on a 'new' surface (I do this routinely)... If the shaft surface is not really good enough, use a speedi-sleeve. I have used these on many occasions and they work very very well. With this particular surface, you just drive the sleeve on and you don't even have to remove the installation section of the sleeve. Just drive it on, assembly it...

                  Speedi-sleeve is now owned by SKF, it was Chicago-Rawhide.

                    For setting the seal deeper, I made a tool... (Of course I did... )

                        I've got 3 pre alphas all used on GM 120hp engines.
                        I've already been moving those seals around finding a clean spot on the yoke shafts. I have pressure and vacuum now but it's only a matter of time.
                        Can I use those Speedy Sleeves you mention ? I went to the link and got real confused (which is normal for me)

                        If these pre alpha yokes are the same as yours can you give me the sleeve part numbers? for the new seals too ?

                        I always knew there was a way to do this, just assumed the only way was to mill and custom seal

                        Great thread by the way !!!

                          If what you have is an MC-1, then it's the same size as the Alpha one and the Alpha One Gen-II... They all use the same sleeve..

                          From memory, the sleeve is for a 2-1/4" shaft and almost 1/2" long... (That's a 99227 for the standard sleeve, and a 99838 for the 'Gold')

                          The seal part number is 26-823894

                            BTW: Didn't mean to offend with the Merc name. Around here ( SE MI ) whenever I mention Mercruiser, everyone chants "Alpha Alpha Bravo !!!!! " Seems no one realized there was anything before the alphas, let alone EZ Shift, MC-1, R or MR and a TRS is only a myth.
                            I only try to cut off at the pass " are you sure ? " question.
                            All my drives are 259XXXX to 425XXXX Serial numbers. With 20-24 upper gears.

                            I'll be sure to watch my language in the future

                            Thanks for the part Number. There's a distributor nearby.

                              Easiest way to deal with that is to post the actual model (MC1, R, Alpha One gen II, Bravo III, etc), the year and the complete serial number... Posting partial serial numbers is useless, nobody can do any parts or service information searching on partials....

                                I had that puddle of lube in my new DS bellows, after a seal job last spring. And my suspicions are verified. "Assemble the oil seal into the oil seal carrier by pressing it with the lip of the seal facing away from the stepped side of the carrier" does not mean the pic below. If they would just say "Garter spring to the bearings" I probably wouldn't have screwed it up.

                                Also my yoke seal surface looks like it could use some help. I've used achris 's method at least once. I've got some time to ponder the sleeve or a new gear yoke. Thinking I'll take the plunge with a new yoke. I want to button this thing up and walk away for a long time.
