Mercury MANIFOLD 4 Cylinder (118-1955-1)

Isn't it true that exhaust manifolds have an infinite lifespan? Even if they stopped working, it shouldn't be a big deal. These are common responses when asked about their boat's manifold. Unfortunately, exhaust manifolds are critical, and no attention to them can result in costly issues like an engine rebuild.

A manifold is a complex metal casting that serves as a pipe within a pipe. It collects extremely hot exhaust gasses directly from the engine into an inner "pipe" or long chamber, frequently cooled by raw water flowing through an outer casing.
