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.
