    Hello Everyone,
    I need to reseal 3 lower units. Does anyone know of a good substitute for the sealer 1000 that the service manual calls for? I’ve seen a video on the tube that says 3M 847. But that stuff isn’t available anywhere. I was hoping for a sub that I could pick up locally.

    Thanks in advance,
    Shawn

    3M 847 is what you want to seal lower units and you can order it on-line.

    I have also used Permatex Aviation Gasket #3 but that does not always seal properly. Best to use the 847.

    Some folks also use Permatex Ultra Black gasket maker.

    Go with the Permatex Ultra Black Silicone Adhesive. It’s easy to work with, readily available, and bullet proof if allowed to cure properly.

    Thanks for the replies guys. I will order a tube of 847. I’m going to do one with 847 and one with the Ultra Black just to see. Hey its a hobby so why not.

    I have used 847 for a while now. While up at Tomahawk this year, there were a group of *cough* fine gentleman* cough*, that were using the Permatex Ultra Black.
    While watching those, *cough* fine gentleman* cough*, use the Ultra Black, I noticed how much easier it was while sealing gear cases, than the 847.
    Other pluses include, the can of Ultra, did not puncture like the paper thin 847 tube, the Ultra black was also very easy to apply from the canister with the attached spout to control the bead and where it went. I have since bought a can of Ultra Black for future use when I run out of 847, which by the way, got punctured while in my tool case. 🙁

    The 847 can be pretty messy to work with so maybe I’ll try the Ultra Black on my next gearcase. If I remember correctly, doesn’t the Ultra Black need to cure for an hour or so before you fully tighten the case fasteners?

    Direct from the can:

    Apply a 1/16th to 1/4 inch continuous bead to one surface, surrounding all bolt holes.. Assemble parts immediately: finger tighten until material begins to squeeze out around flange. Let dry one hour, then tighten to torque specs, allow 24 hours to fully cure before filling with fluids.
    NOTE>>>>
    NOT to be used as a head gasket or in contact with gasoline!!!!!!!!!!!!!!!

    Thank you for the info and procedure Richard. I will do it just like you describe. But when you say a “can” of Ultra Black, does it not come in a tube. the “Ultra Black” I picked up was in a tube not a can. Just making sure I got the right stuff.
    Thanks again.

    It is available in either form, the can seems more logical to me…
