Abstract
A moisture inhibitor system for wet exhausts as utilized in marine applications such as boats and other watercraft. The preferred embodiment of the present invention contemplates an exhaust manifold having an inner exhaust passage which has situated therein a collection barrier or raised pocket situated to collect moisture migrating from the exhaust port, generally at the stern of the vessel. The collection pocket is heated by the exhaust stream, and is formed to collect and retain the migrating moisture, while simultaneously the heated walls of the collection barrier evaporate the collected moisture forming moisture vapor, which moisture vapor is urged through the exhaust passage and the exhaust port, where it is leaves the system. The system thereby prevents moisture migrating up the exhaust passage from reaching the engine. In the preferred embodiment of the invention, the exhaust pipe includes a generally vertical portion emanating from the engine, and an elbow at the top of the vertical portion communicating with an exhaust conduit situated generally horizontally, but with a slightly downwardly angled path leading to the exhaust port at the stern of the vessel. In this embodim…
