  • Works great
As advertised. Tight fit and works well. Naturally,under pressure some water will escape from the muffs but there is plenty of flow to cool the engine.

  • Provides great water flow
worked great to provide more than adequate flow, but they have a tendency to vibrate away from the inlet ports after a while

  • Worked Perfect
Worked great. Used it to winterize Mercury Pro XS 175 4 stroke. Some leakage but not enough to matter.

  • Doesn’t apply enough pressure
I wish I would have splurged for the thicker one. The rubber is a bit flimsy and water just spills right out.
