Hi All. Just wondering if the water-cooled exhaust manifold on this engine has an anode somewhere? I know the heat-exchanger has one which I change over regularly but nothing obvious on exhaust. Maybe no dissimilar metal so anode not needed? Mine is in good (external) condition with no signs of corrosion. Thanks is anticipation of a response.

The manifold is coolant cooled.
Coolant is not an electrolyte.
Unless it's really old, and even then it wouldn't be anywhere near salt water level.
