If your exhaust gets to 1800*F you do not need to worry about corrosion.

As to the compatibility issue, my zincs are in good shape. The elbow is bolted to the cast iron exhaust manifold with a gasket between. The original gasket was a fabric (asbestos?) sandwiched between two thin sheets of stainless. I don't know what the new one will look like. Might just be a single thickness of stainless, so we could have three different metals in contact with the water. The other end is isolated by the 3" exhaust hose, so it shouldn't be a player.

The elbow cam in at noon today. $195 for the welded exhaust flange. $195 for the cast elbow. $20 to ship. $410 total, and received 48 hours after ordering. Well done, Trans Atlantic Diesel! After hunting up a wrench large enough to put it together, it went on like a glove! The aluminum casting is an exact match. The threaded flange piece is longer than the original, but not so long as to be a problem with the hose. The two parts were loose, so you have many options as to alignment of the elbow. Since the flange is square, you only have worry about the final 90 degrees of your location. For you ex military types, we're FMC and Code 1. On to Cleveland in the morning!

Nice, Bilgewater. I'd use anti seize on the bolts if it was me.

RTF - Yeah, I'm slackin' with the followup. If time wasn't an issue, I would have painted the inside with RustOleum Zinc Cold Galvanizing spray, like I did on my props. Then painted the rest RustOleum blue. Maybe in the fall.

Capthead - Funny, I have Lock Tite in my toolbox, but no anti seize. Have to get some in there. Luckily, they came off with no effort.

Does this really work, RustOleum Zinc Cold Galvanizing spray on my props?
Thanks,
