OMC Adhesive M

[stanky]

Okay, I've done my homework and found that OMC Adhesive M is the same thing as 3M's #0847 sealer, Marprox Sealer 1000, and Boat Armor Sealer 1000. The problem is that I can't find ANY of them - not even on the internet! <br /><br />Somewhere in my search, I came across Permatex Gasket Dressing & Flange Sealant #25249, which was alleged to have "replaced" OMC Adhesive M. I think I can find this stuff, because many auto parts stores sell Permatex products.<br /><br />So my question is this: Have any of you heard of this Permatex stuff and is it at least as good as the OMC Adhesive M? Does anyone know of a place that sells any of these products (Adhesive M, Marprox, etc) online?

Well, I removed the gearcase on a 1998 Evinrude 9.9 4-stroke to search for a missing shift rod grommet on the lower motor cover that I thought had fallen into the gearcase housing. Not finding it, I am now just replacing the gearcase without the grommet. I was going to use this sealant on the water pump impeller housing o-ring and on the water tube grommet.

Re: OMC Adhesive M

All you need is a little grease in the water tube grommet to make the water tube slide in easier. No sealant really neccessary<br /><br />If your talking about the oring on the impeller housing, same here. If this oring is really flatened out, you may condiser replaceing it. Cheap part...PN 319085. Right around 83 cent.<br /><br />While we're in there.....when was the last time ya' replaced the impeller?

Re: OMC Adhesive M

The original owner replaced it about a year before I bought it. I don't think they used it much after that, but I don't think they ran fresh water through it on those occasions when they did use it in the bay. I had about a year's worth of use on it.<br /><br />The o-ring does look flat so I will take your advice and get a new one. Thanks!

Ishopmarine.com sells it. Just click on the Index for Genuine Evinrude/Johnson in the middle of the page. Scroll down, it's in the left hand column of the list.<br /><br />Since you have the leg off, might as well rebuild the water pump anyway. Cheap insurance.
