    There are automotive gasket sealants. However, nothing quite like the OMC sealer. A can will last you years for about $10.00. I'd just get the real stuff and forget the rest.

    If no one already has it, this is a stock number to Triple Guard Grease, 8oz. Part# 508298. Have found a couple of E-Commerce sites that at least have it listed on their sites

    Thanks guys, I take it the aviation sealer is as good or better than the OMC sealer.
    I need to pick up the grease also..

    Plus can i use marine wheel bearing grease in the u-joints or is the triple guard better? The omc manual says to use wheel bearing grease in the u-joints and triple guard on the rest..

    Have you tried a BRP dealer? There is this belief current out there, that OMC stuff isn't readily available anymore. Yet I can get most, if not all my parts, directly from a BRP dealer.

    I also read in several places that the aviation gasket sealer is an appropriate replacement for the OMC gasket sealer. When I searched for the OMC stuff online, one Boating Parts Store even listed the aviation gasket sealer as superceding the original OMC sealer.

    Also heard that Johnson/ Evinrude (BRP, as above) has something very similar (if not the same) as the OMC stuff, and that there is a Merc product that is very similar as well...

    I did a bunch of searching on this last spring. The one thing I remember is that along with being a gasket material it is also a thread locker. Here are the notes I copied from different places around the net.

    "OMC Gasket Sealer is the same as Merc's Perfect Seal. In the automotive trade it is known as Perfect Seal #4

    Loctite 30517 is exactly the same as OMC Gasket Sealer

    Note that Permatex Ultra Black is an equivalent to OMC Gasket Sealing Compound."

    I used Merc Perfect Seal.
