Keep Your Marine Engine Running Strong – Flush with Confidence
Every time you take your boat out, saltwater, sand, silt, and debris find their way into your engine’s cooling system. Left unchecked, they can cause corrosion, clogging, and costly repairs. Flushing after every use isn’t just recommended—it’s essential.
Our Heavy-Duty Rectangular Boat Ear Muffs are engineered to make that job quick, effective, and worry-free. Built from durable rubber with a smart, secure design, this flushing kit delivers maximum water flow directly to your engine’s water intakes—so you can rinse, de-salt, and winterize with complete peace of mind.
Compatible with Mercury & MerCruiser Engines
Compatible with 20hp Mercury and Mariner and higher 2-stroke outboards, 9.9-15hp 4-stroke Mercury BigFoot outboards, 2005 and newer 8-15hp 4-stroke outboards, all MerCruiser sterndrives and Mercury High Performance Torque Master gear cases.
Note: Always turn on the water supply before starting your engine, and never run the engine without water flow.

  • Perfect Compatibility: Our boat ear muffs are compatible with Mercury and Mariner 20HP and above 2-stroke outboards, 9.9–15HP 4-stroke BigFoot engines, 2005+ 8–15HP 4-stroke outboards, as well as compatible with MerCruiser sterndrives and Mercury High Performance Torque Master gear cases
  • Durable Rubber Motor Water Flusher: The boat water muffs are built with durable rectangular rubber cups that create a tight sealing around water intake ports. The larger sealing surface delivers strong and consistent water flow directly into the cooling system while minimizing water leakage during engine flushing
  • Boat Motor Flusher with Secure Rod Design: Our reinforced through-rod design securely holds the outboard earmuffs on the lower unit. Ideal for engine testing, maintenance, and outboard motor flushing without worrying about accidental disconnection
  • Upgraded Connection with Built-In Shut-Off Valve: Features a standard garden hose fitting for quick installation in seconds. The integrated water shut-off valve allows convenient flow control without disconnecting the hose, making marine motor flush easier and more efficient
  • Protect Your Boat Engine: Ideal for common water flush, removing internal salt, silt, foreign vegetation, and winterizing. Provides a reliable cooling water flow, helping to prevent internal corrosion, salt buildup, and blockages, extending the life of outboard or inboard engines
