    I will add the corrosion protection

    I ran lots of aluminum parts including the intake and Edelbrock log style exhaust on my 1975 18’C but planning differently this go around.
    I’ll have either anodized or coated aluminum, cast iron, or stainless for parts that will have raw water running through.
    Yes, the boat will likely get flushed after using but...
    Thank you, Patrick

    Harden seems to be the least expensive at $1600 but charges an extra $200 for coating for salt water and an extra $400 for the longer stainless risers.
    Stainless marine $2700 for basic kit so most expensive other than tubular headers.
    Eddie marine is $2000 with anodized manifolds and long stainless risers.
    Imco similar to Eddie but $2300

    Leaning toward the Eddie Marine...

    Thoughts?
    Convert to fresh water cooling. plumb coolant through manifold and raw water through elbow; use a dry joint exhaust. mine is going to have FWC/heat exchanger.
