Non-Hardening Sealer for Rebuild?

[Mik]

I've got my 1985 V6 150hp Evinrude block bored out and ready to start re-assembly (all new pistons, 1 at .030 over) and the manual that I have tells me to use a "non-hardening" sealer on the gasket surfaces and the threads of some of the screws.<br /><br />Can someone fill me in on exactly what I can use for the "non-hardening" sealer?<br /><br />I do have the Permatex anarobic "gasket-maker" for the crankcase.<br /><br />Mik

OMC/Bombi sells the stuff. It comes in a small can with a brush in the top. Sealer 1000 is another and should be avaliable at an auto parts place. I would get the OMC stuff. It is cheap compared to the possible consequences of using the wrong stuff.

The correct sealer is OMC Gel- Seal, The surface has to be proparly prepared for this sealer. All old sealer has to be removed. When you have the old sealer removed with a sharp scaper, clean with acetone, or lacquer thinner, then prime the surface with loc-tite primer. Before you aply the Gel-Seal, wash your hands with soap & water. This sealer has to be free of any contamination or you will have a blow-out between the case halve's.

That's not what you want to use for the crankcase halves. You need the stuff R.Johnson mentioned, or the substitutes Loctite 518 or Permatex 51813. I could be wrong about the permatex number, but its something like that.

Permatex #4 aviation gasket sealer, this is the same stuff, also called Gasket Goo. It's what I use on all my gaskets (except head gaskets), never had a problem.

I do have the Permatex 51813. I'll have to find some of the locktite primer.<br /><br />Thanks for the help. <br /><br />Mik

Mik, I've never used primer and have never had any sealing problems. Just clean the surfaces very, very good and wipe with acetone or even alcohol.

I noticed that the instructions on the 51813 mention to spray one side with the primer and coat the other side with the gasket maker. Apparently it hardens it.<br /><br />Mik
