    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!

      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

    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.

    Thanks for the part numbers, but I heard they upgraded the top seals to a one piece assembly?

    • @605BOLT
      @605BOLT  Год назад

      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.

    • @605BOLT
      @605BOLT  Год назад

      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?

    • @605BOLT
      @605BOLT  3 года назад

      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

    • @605BOLT
      @605BOLT  3 года назад +1

      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. 🤔

    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.

      Oil obviously is coming from the drive case. If it's in the exhaust bellows area or the u joint cavity, something is leaking.

    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
