The FLUSHMASTER gives boaters a simple, automated way to flush two outboard engines without running the motors or splitting water pressure. This 2-outlet controller includes two 9-foot marine-grade hose kits, offering extra flexibility for wider engine spacing, dock layouts, or trailer setups that need a little more reach.

Press the button and the system handles the flush cycle automatically. Each engine is flushed individually for a timed duration, then the unit shuts off and blocks water flow when complete.

Key Features

• Built to Handle Marine Conditions: Waterproof construction and rugged materials help it stand up to repeated dockside use.
• No-Hassle Setup: Comes with batteries and two hose kits, so there is no wiring, programming, or plumbing required.
• Walk-Away Convenience: Starts with one button and stops automatically when the flush cycle finishes.
• Proper Pressure Flushing: Flushes engines one at a time to avoid reduced flow from splitting water between motors.
• Added Hose Reach: Dual 9-foot hoses provide more routing flexibility without becoming bulky.
• Works Your Way: Connect through OEM flush ports, onboard water routing, or optional quick-connect fittings.
