Flushmaster Outboard Flushing System – 2 Outlet with Two 5' Hose Kits – SM-FM2005
Keep your outboard engines running clean and corrosion-free with the Flushmaster SM-FM2005 Dual-Outlet Outboard Flushing System. Designed for convenience and long-term engine protection, this system allows you to flush two outboard motors simultaneously using a single dockside water connection.
The Flushmaster system permanently installs in your boat’s transom or splashwell, providing quick, hands-free freshwater flushing after every use. Simply connect the included hoses and turn on the water—no need for engine muffs or awkward hose setups. Regular flushing helps remove salt, sand, and debris, extending engine life and maintaining peak performance.
This kit includes two 5-foot hose assemblies, making it ideal for twin-engine boats or applications requiring dual water outlets. Built with marine-grade, corrosion-resistant components, the Flushmaster is engineered to withstand harsh saltwater environments and frequent use.
Perfect for offshore, coastal, and saltwater boaters, the Flushmaster SM-FM2005 delivers professional-grade reliability and ease of use while protecting one of your boat’s most valuable investments.
Key Performance Features
-
Simultaneous Dual Flushing: Features a 2-outlet manifold that splits a single dockside garden hose into two dedicated lines, allowing you to run both engines at once (or flush them while they are off).
-
Two 5' Hose Kits: Includes two high-quality, 5-foot lengths of reinforced marine hose. These are the perfect length to reach from a central transom-mounted manifold to the flushing ports on each engine.
-
Corrosion-Resistant Construction: The manifold and fittings are designed for the marine environment, utilizing materials that won't rust or "weld" together after exposure to saltwater spray.
-
Quick-Connect Ready: The system is designed for easy setup and teardown, making it much more likely that you (or your crew) will actually perform the vital engine flush after every outing.
-
Clear Flow Design: The internal diameter of the manifold is optimized to maintain high GPM (Gallons Per Minute), which is critical for modern high-horsepower outboards that require significant water volume to cool properly.

Best Practices for Flushing
-
Check Your Manual: Most modern outboards (Yamaha, Mercury, Suzuki) have a dedicated flush port. Ensure you know whether your manufacturer recommends flushing with the engine running or engine off.
-
Water Pressure: Ensure your dockside water pressure is fully turned on. Since the SM-FM2005 splits the flow, you need a strong source to provide enough volume for two engines.
-
Visual Confirmation: Always check that water is "peeing" out of the tell-tale or exiting the exhaust on both engines to confirm that the manifold is delivering water equally.
Protect your engines and simplify maintenance with the Flushmaster Outboard Flushing System – SM-FM2005, the efficient, reliable solution for dual-engine freshwater flushing.
