Sierra 18-9009 Inboard Flusher, Universal Fit for Most Inboard Marine Engines

The Sierra 18-9009 Inboard Flusher is a universal engine flushing attachment designed to connect a garden hose to an inboard marine engine's raw water intake for flushing after saltwater or brackish water use. Regular flushing removes salt, sand, and debris from the cooling system, helping to prevent corrosion and blockages in the water pump, hoses, and heat exchanger. The flusher is built from metal with a silver finish for durability in the marine environment and connects via a manual, engine-mount style fitting. It is designed to fit most inboard engines, making it a practical addition to a boat owner's maintenance kit for routine post-use care. Each unit ships as a single flusher (package quantity of 1) ready to attach to a standard garden hose for straightforward use at the dock or in storage. As a Sierra product, it is engineered to meet the demands of the marine environment and is backed by Sierra's customer satisfaction warranty covering defects in workmanship and materials for the useful life of the product.
