Style: Dual Sided Muffs


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. Better Boat, a family owned American company, Miami Beach, Florida.

  • Inexpensive andconvenient
Style: Round Muffs
Arrived in a couple of days. I have used it five or six times so that I can supply water from my garden hose to the lower unit and run the boat motor while it’s on the trailer in my driveway. Very handy inexpensive way to get the ball ready for the season.
