  • AAA+++, GET THESE "ROUND" MUFFS🤟💪
Style: Round Muffs
OUTSTANDING!!! PLEASE PLEASE READ!!! I need to say that I bought a 22 ft center console with a 2000, 225hp OMC Johnson outboard and I have not been able to run my boat at all because it wasn't pushing water out the weep/pee hole... This was a huge issue being it's a new purchase and I needed to see how the boat runs before putting to much money in it.. Anyway I had the rectangle muffs to hook up so I could run the boat on land. THEY DID NOT WORK, so I almost spent 1000$ for a new waterpump.. Before I did that I was told to try the "ROUND" muffs like these. INCREDIBLY these ROUND muffs were all I needed. The water pressure is double vs. the rectangle muffs.... So blown away. These ROUND muffs probably saved me 1000$. I wish EVERY boat owner with an outboard could read this post because it is crazy how such a little investment changed my boating experience. Give these ROUND muffs a try!! ... show more

  • Cheap and flimsy material!
Style: Dual Sided Muffs
I strongly advise against purchasing these; I reiterate, avoid these products. As a Florida resident who uses my boat weekly, I've experienced significant issues. The rubber hose exhibits a propensity to bend, restricting water flow. This has repeatedly triggered my engine's overheat alarm due to insufficient cooling. Furthermore, the blue 90° elbows are constructed from flimsy, inexpensive plastic, rendering them prone to breakage. For optimal performance, I recommend sticking with the more economical metal-frame muffs. Cost and aesthetics should not be the sole determinants of quality. ... show more
