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. Fresh water exits the outlet of the primary section impeller through hose and continues towards the fresh water flushing valve for flushing purposes. Being mounted on the common shaft, the secondary section impeller rotates with the primary section impeller. Rotation of the secondary section impeller creates negative pressure or vacuum at the inlet section and draws water from the muffler, silencer or suppressor. Water from the muffler travels through the secondary section impeller and then discharges overboard.
