  • Water-lift muffler evacuation device
    Patent number: 5655937
    Abstract: A device is disclosed which allows water-lift mufflers, silencers or suppressors to be fully flushed, while in or out of the water, without running the engines. The device can be mounted between a remote access panel or control panel and a conventional fresh water flush valve. Fresh water flow provides fluid power to a primary section impeller or turbine, where power is then mechanically transmitted to an evacuation or secondary section impeller or turbine through a shaft on which both impellers mount. The inlet section of the secondary section impeller connects by hose to the drain plug universally present on marine engine mufflers, silencers and suppressors. The outlet section of the secondary section impeller connects by hose to an overboard drain. Fresh water, having sufficient flow and pressure, applied to the device drives the primary section impeller, causing the impeller to rotate.
