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, South Florida.

  • Muffs that apply water to both sides.
Style: Dual Sided Muffs
TheseMuffs are a great product. Well put together and they’re split in the middle to take water in on both sides. Which is a plus you want to get as much water through to the system as you can when doing it with a hose. I recommend those over one sided ones speedy delivery very happy with them.

  • Very nice product! Love the compatibility of it.
Style: Dual Sided Muffs
Works wonderful! No leaks, fits my Suzuki outboard perfectly, very easy to slip on after it’s wet, love how you can adjust it too fit your water intakes! Very compatible with my outboard or even an inboard out drive! Very portable, keep it in my center console of the boat . Highly recommend this product, love how water comes out both sides! ... show more

  • Do not buy, get the metal version
Style: Dual Sided Muffs
Horrible product, should have known better than to buy a plastic set. Broke immediately trying to put on. Do not buy. Broke at the hose connection.
