    Default Shaft packing upgrade

    So I need to replace my shaft packing due to the fact that it is laeking a steady stream of water. So I called AWS today and they said that they have a no keak fully sealed upgrade kit for that and it runs abou $150. Around $300 installed but I am just gonna get the parts and do it myself. I was just wondering if anybody has done this and if there is any part of this upgrade that is a headache? Other then the location of course...

    I don't have any experiance with installing one, but my boat (allegedly) has it already, but for some reason my bilge is always full. Dealer said nothing is wrong, but the dripless shaft seal sure seems to drip on my boat, lol.

    I only needed a 2nd person to help push the shaft when installing the seal. Couldn't get enough leverage from inside the boat.

    Six years ago, I replaced the wax cord with a graphite cord with no leaks since. They have since come out with the Teflon cord. Either way, these cords hold up much better than the wax cords and I still can't figure out why they still use it.

    stretch,

    I was initially going to install the dripless shaft seal like the new Moombas have but I learned that the new packing ropes are a lot more durable and drip a lot less than the old wax packing rope, and cost less than $10 vs $150 for the dripless seal. So I thought I would give the new rope a chance and if it doesn't hold up after a couple seasons, then I may spend the $150 on the dripless. But for less than $10 and about 30 minutes of work, it was a no brainer for me. I figure a have a lot better things to spend $150 on.

    Hope that helps.

    I have the same issue, I believe the water is coming from somewhere else. I do take some comfort in the fact that you are having the same issue as me.

    My bilge never had any water in it. Now I'm not so sure. I had it in the driveway today and started it up with the fake-a-lake plunger and water was streaming out of the shaft opening. I would imagine it goes the other way too??
    Not sure what to do other than try and get it on the water and check? Why the heck would it start doing this out of the blue? Supposed to be dripless?

    If the water was coming out of the shaft log, outside of the boat, it is because the seal system is water lubricated from the motor. Water is pumped to the seal and exits through the log down the shaft. The system is dripless as long as the alignment is good and the shaft does not wear one side or the other of the seal.

    If it is dripping in the boat then the seal itself is damaged. The seal can be replaced and the motor would need to be aligned.
