The Flushmaster 4-Outlet is the ultimate tool for single to quad-engine maintenance — fully automated, fully portable , and built tough for life on the water. Just connect, press start, and walk away while Flushmaster delivers a full, hands-free flush that protects your investment and extends your engine life. Engineered for real-world marine conditions, the Flushmaster is built with marine-grade materials, 316 stainless steel internals, and brass screw inserts to stand up to harsh saltwater environments. It's IP67 waterproof certified and hurricane-tested, so you can trust it to perform — rain or shine, trip after trip. Designed for total convenience, the battery-operated system lets you flush anywhere your adventures take you. Whether you're on a boat lift, dock, trailer, high and dry, or marina, the Flushmaster adapts to your setup. Hard plumb it in permanently, or connect easily with a reinforced hose.
