View Full Version : Cast Stainless Merc. Ex Elbows

05-05-2011, 09:13 PM
When I upgraed my old Formula 27 about 12-14 years ago I bought two Cast Stainless Steel Mercruiser 4 " center rise exhaust elbows along with new cast iron Merc manifolds.
These looked almost like the stock cast-iron Mercruiser elbows.

Are these 4" Cast Stainless Steel Merc exhaust elbows still offered by Mercruiser , or any other supplier?

I need a pair for my Donzi benchseat 18 Small Block project.

These cast SS elbows were indestuctable.
The best stock-style exhaust elbows I ever owned.

I should have swapped them out with cast-iron & kept them when I sold this boat five years ago.
Those elbows are still going strong today for the boat's new owner.
Typicaly in SaltWater use I find you need two sets of ebows for each manifold's useful lifetime.

Were these also made for the Small Block Chevy Merc manifolds ?

Will these also work on the Small Block Chevy Mercruiser manifolds ? I didn't think so.
The SBC elbow are smaller are they not ?

Yes that is what I had before building the 383.

Phil. Do u know if mercruiser still makes the SS riser an is
the elbow the riser? My manifolds are like new so I think
I will keep them for now. But SS risers sound nice lookin...
I have the 6.2l in my classic like Ghost is sayin about the
salt that is what is going to be my concern also
