The FLUSHMASTER is a portable, marine-grade flushing system designed to make routine outboard care faster, cleaner, and more consistent. This 2-outlet controller includes two 7-foot marine-grade hose kits, giving standard twin-engine setups a practical balance of reach and easy hose management.

With just a push of a button, FLUSHMASTER flushes each motor one at a time for a timed freshwater cycle, then automatically shuts off and blocks water flow. It eliminates the need to stand by the dock, swap hoses, or guess how long each engine has flushed.

Key Features

• Engineered for the Marine Environment: Built with waterproof housing and marine-ready materials for dependable dockside use.
• Connect and Start Flushing: Includes hoses and batteries so you can begin flushing without wiring or extra setup.
• Hands-Free Flush Control: Runs the flush cycle automatically and shuts off when complete.
• Sequential Engine Flushing: Flushes one engine at a time to maintain strong water pressure and avoid split-flow flushing.
• Balanced 7ft Hose Length: A smart choice for standard twin-outboard layouts with moderate spacing.
• Quick-Connect Ready: Works with OEM flush ports and optional quick-connect fittings for flexible routing.
