I have the original Mercruiser exhaust from 1989 454-420. Apparently they are (gaskets) discontinued, according to 3 merc dealer here. I need 4 gaskets, those between the manifold and the riser.They are big rectangular gasket, maybe 1/4 thick, with many holes each one beside the other hole, all the way around the gasket. It's made out of a kind of rubber just like a tire tube.

This may be the reason a could not go to Lake George run next week and I don't feel like missing this for 4 gaskets...

Pm me if you have that, or if you know someone who could have this, or if someone even has a good used set!

Thanks guys for your help!

You can't use a new style riser gasket??

Can you post a picture?

How many bolts hold down this gasket, 4 or 6? Some dimensions or a picture would also help us in getting the right gasket for you.

i HAVE SOMEONE GONE TO PICK ONE UP AT MY ENGINE BUILDER AND i'LL POST PICTURES LATER.

looks like 6 bolts. Here is the picture. Could not find these on Bam Marine.
