    Alpha One Gen 2 - Driveshaft Seal - P/N: 26-864319

    I see a very subtle undercut shape on one side. Here is another picture showing the side view. Is that the slight flange that you are referring to.? Thanks very much.!

    Alpha One Gen 2 - Driveshaft Seal - P/N: 26-864319

    Question about the Double Seal that goes into the bottom of the upper drive housing. The two seals appear to be identical (one seals OUT water, and one seals IN gear lube). But the outer portions of the two seals are different. Please see the attached pictures. Which direction does the seal...

    Valve Lubricant

    1996 MerCruiser 4.3 LX Gen+ Operation & Maintenance Manual # 90-807795962. On page 51 it states: "To maximize the life of valves and valve seats on your MerCruiser engine, use Quicksilver Valve Lubricant (92-90131A12) regularly." It appears this P/N has been superseded by P/N-826259A12, but that...

    Question About Speedi-Sleeve Installation

    Update: I found that a 2" PVC Coupler has an inside diameter of 2-3/8". That worked perfectly as an install tool for tapping the Speedi Sleeve on. And it only cost $1.56 at Home Depot... :) A new question regarding this same topic: Do you guys normally try to remove the tearaway installation...

    Alpha One Gen 2 Shaft Seal Choice

    Engine is a 1996 Mercruiser 4.3 LX Gen+. Outdrive is an Alpha One Gen 2 (S/N: 0F709127). I am currently replacing all the seals in the upper half of the outdrive. So the "drive gear assembly" and the "driven gear assembly" have now both been removed. I did not remove any shims or bearing cups...

    Alpha One Gen 2 Shaft Seal Choice

    The outdrive serial number is 0F709127. Along with the driveshaft seals, I plan to replace the yoke seal. So won't I need to reset the rolling torque after that.? .

    Alpha One Gen 2 Shaft Seal Choice

    I do have Service Manual #14 and I am following the procedure there. And I am replacing the yoke seal as well, so I will need to reset the rolling torque. I thought I had read that the double seal design change did not change the seal cavity. Which would mean that either seal configuration...

    Alpha One Gen 2 Shaft Seal Choice

    Hey, thank you for the reply to my question. The seal I'm referring to is actually #5 in this assembly drawing: https://www.mercruiserparts.com/bam/subassemblydetail/46516838/28171024 Our outdrive is slightly older than that (serial number 0F709127). So ours came with a pair of seals in that...

    Alpha One Gen 2 Shaft Seal Choice

    My effort to recondition our Alpha One outdrive continues. One of the kits I purchased is Sierra seal kit P/N-18-2644. It came with both types of double seals for the driveshaft. One is a pair of seals, and one is the combined double seal. (the seals I removed were the two separate opposed...

    OK. Sounds good. I will use that method. What do you mean by "prep the tool"...? .
