Rubber Motor Flusher — Durable, easy-to-use flusher for larger outboards Key benefits Protects your engine: flushes salt and mineral deposits from the cooling passages to reduce corrosion and clogs. Simplifies winterizing: lets you run antifreeze through the motor quickly and reliably. Fits larger outboards: designed for engines with larger water intake openings and delivers better cleaning performance. Better cleaning power: dual-flow design increases pressure and improves flushing effectiveness compared with single-outlet flushers. Versatile hose connection: includes an adapter to fit other hose sizes so you can use standard dock or garden hoses. Main features Material: constructed from durable rubber to form a secure, flexible seal against the lower unit. Dual design: two outlets provide higher flow and pressure for more thorough flushing. Rotating muff ears: rotate the muff ears to position and seal the flusher over the water pickups on the lower unit for a leak-resistant fit. Compatibility: specifically designed to fit larger outboards with larger water intake openings; adapter included for additional hose sizes. How it solves common problems Removes salt and mineral buildup that can reduce cooling efficiency and cause overheating. Makes winterizing straightforward by creating a tight, reliable connection to circulate antifreeze through the cooling system. Eliminates the need for improvised adapters or awkward fittings that leak or slip off during flushing. Practical use scenarios 1) Post-trip rinsing: At the dock, attach the flusher to a hose and flush the cooling passages after every saltwater outing to reduce corrosion and extend engine life. 2) Winterizing: Before storage, use the flusher to circulate antifreeze through the motor to protect internal passages from freeze damage and corrosion. 3) Routine maintenance: Use during scheduled service to remove scale and mineral deposits that impair cooling performance. What you get A rubber motor flusher sized and shaped for larger outboards Dual-outlet design for improved pressure and cleaning Rotating muff ears for a secure seal over lower-unit water pickups Hose adapter to connect to different hose sizes Simple to use, compatible with larger outboard lower units, and built to help maintain cooling-system performance without complex fittings or tools.
