HYDRA-FLUSH Inboard Engine Flusher Kit

HYDRA-FLUSH™ is a patent-pending modular marine raw water flushing and service platform engineered for modern marine propulsion, HVAC, generator, and auxiliary cooling systems.

Originally developed through real-world field use in Northern Michigan’s demanding marine service environment, HYDRA-FLUSH eliminates the fall-offs, blow-by, poor sealing, and unreliable engagement commonly experienced with traditional static-locking flush devices such as “Fake-A-Lake,” “Flush Buddy,” and other adjustable inboard flushers.

HYDRA-FLUSH’s patent-pending Continuous Upward Force Design maintains constant sealing pressure against raw water pickups and cooling inlets, creating a more stable and reliable flushing connection during maintenance, diagnostics, descaling, winterization, and system commissioning procedures.

Unlike conventional engine-only flush devices, HYDRA-FLUSH was designed as a broader marine systems service interface capable of supporting multiple raw water-cooled onboard systems, including:

• Inboard and sterndrive propulsion systems
• Generator cooling circuits
• Marine HVAC and chilled water systems
• Water-cooled condensers and heat exchangers
• Auxiliary seawater-fed systems
• Raw water priming and circulation applications

The patent-pending modular manifold architecture allows interchangeable inserts and future expansion across varying marine raw water inlet configurations, enabling adaptation across multiple vessel classes and onboard system types.

At the core of the system is a rugged 6061 machined aluminum manifold manufactured in the USA using predominantly American-sourced materials. Unlike plastic-threaded flush devices prone to stripping, cracking, and cross-thread failure, HYDRA-FLUSH is engineered for repeated professional marine service use in demanding environments.

Designed and manufactured in Traverse City, Michigan USA.
