GROCO 1" Engine Flush Kit & Adaptor

The GROCO 1" Engine Flush Kit & Adaptor is an essential maintenance tool for any serious boater or marine engine owner looking to extend engine life and maintain peak cooling system performance. Proper maintenance of the raw-water cooling system is crucial, especially after years of use in saltwater environments where debris and corrosion can accumulate.

This flush kit allows for the clean circulation of freshwater through the engine's cooling galleries without running the engine, effectively removing sediment, salt deposits, and other contaminants. It features a durable adaptor that threads securely into the engine's raw-water intake and a hose connection compatible with standard garden hose fittings. The design ensures adequate freshwater flow to flush internal passages without risking seal damage.

Ideal for inboard gasoline and diesel engines, this kit is perfect for cruisers, trawlers, and sportfishing boats operating in saltwater, brackish, or sediment-laden freshwater environments. Its marine-grade construction withstands repeated exposure to harsh conditions, making it a reliable choice for maintaining your engine's cooling system.
