    • fits perfectly, well made, good value
Style Name: Round Muffs
I like to flush out my motor after each trip to the lake. The ear muffs I used for years finally gave out. This has made an excellent replacement for it. It is well made. I expect to get many years of use from it.

    • Great for your post boating trip motor cleaning needs!
Style Name: Round Muffs
Worked ok, but did not grab suction on my boat Motor. Probably need a rectangular shape to get better grip for shomax 175. If it had been a different shape, i think it would have worked well. Easy to attach, decent quality, great for the price!

After wrestling with flimsy, poorly fitting outboard flush muffs, I finally found a gem with this set. These ears are a cut above the rest, blending smart design with rugged durability that makes engine testing a breeze. I need them very rarely (for a dinghy), and in between uses they are not stored in the best of conditions (on a sail boat). What sets these muffs apart is their versatility, fit, and ease of use. The rectangular pads pivot from horizontal to vertical, adapting seamlessly to various water intake designs. They snap on with just the right amount of tension: secure enough to stay put without slipping, yet not so tight that you’re fighting to attach them. The rubber grips like a champ, covering intake ports completely, and the hose connection locks in tight. Recommend 👍🏽 Helpful?👇🏽 ... show more

Fits my Mercury 50 and works like it should. No issues here. Good build quality. Only ran it once, but did the job. Easy to use, good value for the money.

I saw that a neighbor had one of these and he got his "a long time ago" so I have been filling a can with water for my outboard. This is much better. A tremendous time saver and value.

    • Very good quality flush muffs
Style Name: Rectangular Muffs
I very much like this style better than the circular muffs. It can pivot to vertical from the horizontal position to match up to most of the water intakes you hook it up too. It's tight but not so tight it's a pain to get on. The rubber doesn't slide around once you get it in place and the hose connection doesn't pop out of it very easily so that makes it top quality in my opinion. I've had tons of these through the years that are cheap and just don't last or don't even work. This is the best set I've tried so far and it was priced pretty much what I paid for all the other ones that were not good 🤷. I work on outboards so I've used these on multiple engines- a Yamaha f115, a Suzuki df150, a Yamaha 250 SHO and a Mercury 115 4-stroke and it worked and fit awesome with each one of them and yes even on the Yamaha 250 SHO it actually is able to be secured to the nose cone high speed pick up and provide plenty of water ... show more
