I have severe rusting and erosion at the exhaust end of the manifiold, including the exhaust flange and the water exit flange. As you can see the tapped hole for the exhaust flange is almost gone.
Early Model 1965 in Alberg 30.
Had this manifold off 3 years ago, acid flushed and painted. Engine is SW (upper Chesapeake) cooled.
I have never observed any leakage around the water exit, or that these surfaces were wet.
I have a replacement manifold. It's a new model so required some replumbing.
What is likely causing this ???? Any ideas or wisdom would be appreciated.
