Gaskets for marine exhaust
 

What's the collective wisdom out there wrt joints between exhaust manifolds,
risers, and elbows ... use a sealant (e.g. Permatex) along with the gaskets,
or just the dry gasket alone?

I've never had a problem with dry gaskets. If you've got an exhaust
problem the sealant isn't going to help much. Plus, if you have to
replace one, and the gaskets have slots instead of holes for the bolts,
replacing one that did not have sealant is easy, just loosen up the
bolts enought to pull the old gasket out and slide the new one in. If
you have sealant you have to remove the manifold and clean the
surfaces. We all know how much fun it is handleing those heavy
manifolds, while trying to get the bolts started, while trying not to
distroy the new gasket in the process.

There just isn't enough water pressure to be an issue, so dry gaskets are
fine Dave...just make sure mating surfaces are clean and flat. And there is
never a need for any type of sealant on the dry exhaust portion.

Good luck.

When I replaced my manifolds and risers, the shop guys in the marina gave me a
tube of what they called "gasket glue". It's purpose was only to hold the gasket
in place while assembling the parts. It was *not* a sealant like Permatex, but I
don't remember the name of it.

Anti-seize compound makes an excellent exhaust gasket sealer. While
you're at it, use it on all the fasteners as well.
