  • Didn't work at all.
Style: Rectangular
Did not work for my Mercury 90HP Outboard, or for my friends Yamaha 115 HP. We both needed muffs as part of our spring motor startup. Would not recommend this product. Another friend recommended the hose supplying both sides of the motor compared to this one sided hose feed. Can't return since I'm over 30 days :( ... show more

  • fit very well
Style: Rectangular
These "boat muffs" work very well on my outboard Johnson 90 HP motor. The water flushes through motor with very little leakage.

  • The easiest to use
Style: Rectangular
These have been around for years and still no one has invented a better mousetrap. I tried some others that took longer to install and remove, leaked as much and were just frustrating all around. Use these.

  • Without a good seal the water leaks out and does not flow ...
Style: Rectangular
My only complaint is that it does not fit snuggly on my tramsom. Without a good seal the water leaks out and does not flow thru the engine. I fixed the problem by using painters tape to seal the edges. Works great with a little tape.

  • tight fit
Style: Rectangular
holds great on motor. I would keep it out of the sun. I think this rubber will crack in a few years or get stiff.
