Help Tip: If you have a question that has not been answered to your satisfaction in the archives, it is always best to start a new thread of your own. By starting your own thread, you will receive the maximum number of views by forum members.

Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

1. Please do not reply to old topics or hijack existing topics. Old topics of a technical nature are like a library book, Please do not write in them.

2. Old topics should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís topic (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new topic of your own.

4. If you have a question for the original poster (OP) and the topic is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old topic.

5. By starting your own topic, you will receive the maximum number of views by forum helpers that may not even notice your question when itís posted at the end of someone elseís topic. And those answers will be specific to your particular issue.

6. Please do not post to topics that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any topic that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old topic.

7. Posting at the end of any topic is considered to be hijacking the original posters topic which in turn subjects the topic to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive topic asking you not to reply to old topics. The Red banner will read: Please note this topic has been inactive for 90 days. For the best results, please start a new topic.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

    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..

                Re: What to use in place of OMC gasket sealing compound?

                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.

                  Re: What to use in place of OMC gasket sealing compound?

                  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...

                    Thanks, I think i'll check with Napa about the aviation sealer or try to find the BRP stuff online..

                    Thanks for the link also Lyndy

                      Re: What to use in place of OMC gasket sealing compound?

                      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.
