Beschreibung
Zusammenfassung:	The present invention, in one aspect, includes a probe for sensing exhaust gas pressure in an exhaust path of a marine engine during engine operation. In an exemplary embodiment, the probe includes an elongate probe body and an engine engagement assembly secured to the probe body and configured to engage to the engine so that said probe body at least partially extends into the engine exhaust path. The probe body comprises a hollow, cylindrical shaped member, and at least one opening extends through a side wall of the cylindrical shaped member. A cap is secured to and closes an open end of the probe cylindrical shaped member, and a pellet is located, i.e., trapped, within the cylindrical shaped member. The engine engagement assembly includes a threaded portion sized to be threadedly engaged within an opening in flow communication with the engine exhaust path, and a tube connection portion sized to be inserted within a tube.
