Elbow‑to‑Manifold Gaskets

There are two styles of elbow‑to‑manifold gaskets. Gaskets with open water ports are used in seawater‑cooled systems.
Gaskets with blocked water ports are used in closed‑cooling systems. Indicator tabs around the perimeter of the gasket allow
easy identification of the gasket style when the gaskets are installed.
