## Description

Product description

Review: Outboard Motor Muffs - Works great and good quality. Good price and works as designed.
Review: Great motor flusher - This works perfectly on my 200 hp Mercury XPS.

## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Outboard Motor Muffs
*by B***E on May 30, 2026*

Works great and good quality. Good price and works as designed.

### ⭐⭐⭐⭐⭐ Great motor flusher
*by R***P on May 6, 2026*

This works perfectly on my 200 hp Mercury XPS.

### ⭐⭐⭐⭐⭐ They look like quality muffs
*by T***T on May 5, 2026*

I bought these to clean the salt water out of my outboard motor on the back of my yacht tender. They did not work for me but I don't think it was the muff's fault. I think it's the design of my motor. They look like high quality muffs and will probably work on a different motor. I have a 2025 30 horsepower Mercury outboard.
