The FLUSHMASTER is an automated outboard flushing system built to deliver a proper timed freshwater flush to each engine without running the motors or splitting water flow. This 2-outlet controller includes two 15-foot marine-grade hose kits, making it a strong fit for wider transoms, larger boats, or dockside setups that require extra reach.

Once activated, FLUSHMASTER flushes each engine one at a time, then automatically shuts off and blocks water flow. It helps take the guesswork out of flushing while making engine care easier to do after every trip.

Key Features

• Marine-Ready Construction: Waterproof housing and durable materials are built for real use around docks, boats, and saltwater.
• Everything Included to Start: Comes with batteries and two 15ft hose kits for a ready-to-use setup.
• Automated Flush Control: Runs a timed cycle and shuts off automatically, so you do not have to watch the clock.
• Sequential Flow Efficiency: Flushes each engine separately to help maintain full water pressure.
• Extended Reach Capability: Dual 15-foot hoses make routing easier on wider transoms and larger dock layouts.
• Adaptable Connection Options: Works with standard flush ports, onboard fittings, and optional quick-connect setups.
