UNIVERSAL FIT: Our outboard motor muffs offer rotating ears and a U channel measuring 10.5" to rotate and adapt to almost any outboard motor and Inboard/Outboard I/O engines. Large ear muffs to flush away engine dirt while allowing easy flushing. DOUBLE SIDED: Increased water supply from two sides offers superior intake compared to old single sided boat motor muffs. The flexible water tight boat muffs measure 3 1/4" by 5" and bend to allow the flusher to snuggly pinch your intakes. STANDARD INSTALL: Our boat ear muffs outboard use connects to a standard hose with an included optional quick connect male adapter end and rubber washer. No tools needed. Use with or without additional marine salt flush kit boat parts. Review: Great motor flusher - This works perfectly on my 200 hp Mercury XPS. Review: Work great, very handy to have! - Work great, let me run my engine on land to make sure it was running ok. Used on a 42 year old boat, I/O engine, and they fit snug, and keep water flowing while you run the engine on land. Only had it running for 5-10 minutes, but the muffs worked great and kept the water flowing into the intake. ## Features - DURABLE DUAL FLOW CONSTRUCTION: Premium rubber ear muffs with flexible water lines and watertight seals built to flush, cool, warm, and winterize your engine. Works as a standalone flusher or as part of a complete winterizing kit. - DOUBLE SIDED FOR SUPERIOR FLUSH FLOW: Two intake cups supply water from both sides of the engine simultaneously. Single sided muffs restrict water volume and can leave passages partially flushed. Dual intake reaches more pathways in a single flush. - FITS MOST OUTBOARD AND I/O ENGINES: Rotating ears and U-channel adapt to outboard and inboard I/O engines including Mercury, Yamaha, Honda, Suzuki, and Evinrude. U-channel is 10.5 inches deep. No tools or modifications required. - SIMPLE MOTOR FLUSH SETUP: Connects to any standard garden hose in seconds with the included rubber washer. Quick connect male adapter included for quick-connect hose systems. No tools or extra parts required. - PROTECT YOUR ENGINE: Saltwater trapped in engine passages causes corrosion that shortens engine life. Flushing after every run takes minutes and prevents buildup before it starts.
