I noticed the same play when i got my bellhousing off the other day on the lower part of the shaft. Must be normal. I ordered a kit anyways because the upper seals are SHOT! Once again you have a video for it. Thanks again man. Slowly getting through my project!
Definitely possible. These parts were ordered through Ron @ JR Marine. He can hook you up if you are wondering about the latest and greatest. This video of mine isn't super recent so I would believe you if you said there has been updates since.
I recently just replaced the bushes and seals in my gen 1. Can confirm the top is a one piece and I would highly recommend sourcing this. It is a superior design than the separate bushing and seal.
Interesting. Well hopefully viewers see this comment but I anticipate this fix even with the two piece will last the life of the boat from here on out.
Verry cool and good videos! Helped me a lot. But I have one question: in Mercruiser detailed drawings for the Alpha One Gen 2, the installation order for the bushing and the two seals is the other way round. Form the exaust side the bushing comes first and then the two seals. Do you know what's the right arrangement?
Hi Jens. Glad this helped you out! I put the seals back in the way I found them on my outdrive. I think possibly either way would work but as far as I know the way I did it in this video is correct. But if you find different information in some Mercruiser documentation I definitely could be wrong. I used a SELOC rebuild manual as reference on my boat. Do you have a link to the image you're referencing? I'd like to take a look out of curiosity.
Oil is coming through my upper shift shaft seal. Does anyone know where it might be coming from? Doing this would probably fix the external leak but I'm worried that the problem is from some other seal internally
Interesting. The upper shift shaft keeps the driveshaft area from mixing with the exhaust and water exiting the engine. Pretty tough to imagine you have that much oil in your exhaust so I would guess that maybe the upper half of the outdrive is leaking near the u joint and letting gear oil into the u joint bellows. Assuming I understand you correctly. 🤔
Whatever works is best. I'm sure every scenario can be different. The threaded rod helped me keep everything straight and lined up but I'm sure there are alternate methods. Glad to hear you got it freed up.
Cool video but unfortunately a few things were done improperly the seals are top an bottom with brass in the middle an should not ever used all thread to drive them in because of possible tearing i use a old shift shft cut it an i drive them in with a hammer an never use break clean on rubber its to harsh i understand not everyone works on boats for a living otherwise great job
Just did this job after watching your vid!
Hey!!!! That's what it's here for. Makes me feel good someone is finding it useful! Thanks for commenting!

Right on. Ya I made the assumption that play like that was bad just like you but I guess that's normal like you said. Seals were toast on mine wow
A big thank you, will have 0 worries doin this myself now!
Glad to hear it! Thanks for watching and commenting!!!
If water got past those seals it shouldn't reach the driveshaft, but it's still good to keep it from getting into that cavity.
Ya i felt like while I was in there it would be good to take care of.
Yes water could come up and reach the drive shaft
@@Patrick-dy7lg Only if there was also a leak between the upper gear housing and gimbal.
Thanks for the part numbers, but I heard they upgraded the top seals to a one piece assembly?

@@TM-cz9tg Yes the upper seal is built into the gen 1, it is different than the Gen 2.
Good info.

Do you have a video on how to properly re-install all of this onto the boat?
Yep. If you check out the playlists on this channel they're all there in the order I did it. 👍
Great video sir
Thanks for the kind words. Glad you liked it. 👊🍺

Mine is leaking lower unit oil from here empty my resivor out
@@samuelbermudez2971 ya. Better replace it if you think it's questionable.
Do you have to take out the bell housing to replace the seals? Or can it just stay on
I don't remember to be honest. I could see it being done in the boat. I took it out because I was doing everything at the time.
@@605BOLT oh ok thanks
Instructions plus really annoying electronic sound track?! Yeah, that's perfect
Either that or listening to my overweight heavy breathing. You pick.
I like the music!
If the upper shift shaft rod seals are bad does water come out or oil? I got oil coming out
Sorry I need a little more context to your problem. Where do you have oil coming out?
@@605BOLT the upper shift shaft what your replacing. my seals are bad and oil is coming out
@@Elite_Eli_Editz oil shouldn't be in there. Sounds to me like something else is leaking.
Oil obviously is coming from the drive case. If it's in the exhaust bellows area or the u joint cavity, something is leaking.
@@605BOLT I’m gonna pull off my lower unit tomorrow
What length 3/8 threaded rod is needed ? I’m about to do this job
I don't know exactly. 18" would be a great plenty though if I remember right. Might get by with just 12" or so.
These bushes are in tight so hard to get out
I had to give a good hit with the hammer.
Got it out eventually. Some people say they can tap them back in or should I use the threaded rod method

Appreciate your feedback. Been 3 years now with no issues.
You sound like casey aflek
Haha. I have never heard that before. I hope that's a good thing 🤣
10:05… 🙈
I don't know what you're talking about.
Very informative, do you fix boats for a living?
Lol. It costs me a living to fix boats. #blessed.
