You still need water in the manifold and risers to keep them cool right?And the raw water goes through a heat exchanger to keep the coolant coil? Right? I’m really asking not being facetious

Yes your right the raw water gets pumped through the heat exchanger then through hoses to the exhaust manifolds outer cavities then back out to the lake. The anti freeze or coolant side of things stays in the engine block. in the intercooler there's copper pipes that the anti freeze passes through as the lake water passes around in the intercooler. Yes the lake water is always being expelled through the exhaust manifolds. I hope that helps?
